# SemVer
The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
[![Stability:
Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
## Parsing Semantic Versions
To parse a semantic version use the `NewVersion` function. For example,
```go
v, err := semver.NewVersion("1.2.3-beta.1+build345")
```
If there is an error the version wasn't parseable. The version object has methods
to get the parts of the version, compare it to other versions, convert the
version back into a string, and get the original string. For more details
please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
## Sorting Semantic Versions
A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
package from the standard library. For example,
```go
raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
vs := make([]*semver.Version, len(raw))
for i, r := range raw {
v, err := semver.NewVersion(r)
if err != nil {
t.Errorf("Error parsing version: %s", err)
}
vs[i] = v
}
sort.Sort(semver.Collection(vs))
```
## Checking Version Constraints
Checking a version against version constraints is one of the most featureful
parts of the package.
```go
c, err := semver.NewConstraint(">= 1.2.3")
if err != nil {
// Handle constraint not being parseable.
}
v, _ := semver.NewVersion("1.3")
if err != nil {
// Handle version not being parseable.
}
// Check if the version meets the constraints. The a variable will be true.
a := c.Check(v)
```
## Basic Comparisons
There are two elements to the comparisons. First, a comparison string is a list
of comma separated and comparisons. These are then separated by || separated or
comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
greater than or equal to 4.2.3.
The basic comparisons are:
* `=`: equal (aliased to no operator)
* `!=`: not equal
* `>`: greater than
* `<`: less than
* `>=`: greater than or equal to
* `<=`: less than or equal to
_Note, according to the Semantic Version specification pre-releases may not be
API compliant with their release counterpart. It says,_
> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._
_SemVer comparisons without a pre-release value will skip pre-release versions.
For example, `>1.2.3` will skip pre-releases when looking at a list of values
while `>1.2.3-alpha.1` will evaluate pre-releases._
## Hyphen Range Comparisons
There are multiple methods to handle ranges and the first is hyphens ranges.
These look like:
* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
## Wildcards In Comparisons
The `x`, `X`, and `*` characters can be used as a wildcard character. This works
for all comparison operators. When used on the `=` operator it falls
back to the pack level comparison (see tilde below). For example,
* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `>= 1.2.x` is equivalent to `>= 1.2.0`
* `<= 2.x` is equivalent to `<= 3`
* `*` is equivalent to `>= 0.0.0`
## Tilde Range Comparisons (Patch)
The tilde (`~`) comparison operator is for patch level ranges when a minor
version is specified and major level changes when the minor number is missing.
For example,
* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
* `~1` is equivalent to `>= 1, < 2`
* `~2.3` is equivalent to `>= 2.3, < 2.4`
* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `~1.x` is equivalent to `>= 1, < 2`
## Caret Range Comparisons (Major)
The caret (`^`) comparison operator is for major level changes. This is useful
when comparisons of API versions as a major change is API breaking. For example,
* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
* `^2.3` is equivalent to `>= 2.3, < 3`
* `^2.x` is equivalent to `>= 2.0.0, < 3`
# Validation
In addition to testing a version against a constraint, a version can be validated
against a constraint. When validation fails a slice of errors containing why a
version didn't meet the constraint is returned. For example,
```go
c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
if err != nil {
// Handle constraint not being parseable.
}
v, _ := semver.NewVersion("1.3")
if err != nil {
// Handle version not being parseable.
}
// Validate a version against a constraint.
a, msgs := c.Validate(v)
// a is false
for _, m := range msgs {
fmt.Println(m)
// Loops over the errors which would read
// "1.3 is greater than 1.2.3"
// "1.3 is less than 1.4"
}
```

Specifically it provides the ability to:
* Parse semantic versions
* Sort semantic versions
* Check if a semantic version fits within a set of constraints
* Optionally work with a `v` prefix
Parsing Semantic Versions
To parse a semantic version use the `NewVersion` function. For example,
v, err := semver.NewVersion("1.2.3-beta.1+build345")
If there is an error the version wasn't parseable. The version object has methods
to get the parts of the version, compare it to other versions, convert the
version back into a string, and get the original string. For more details
please see the documentation at https://godoc.org/github.com/Masterminds/semver.
Sorting Semantic Versions
A set of versions can be sorted using the `sort` package from the standard library.
For example,
raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
vs := make([]*semver.Version, len(raw))
for i, r := range raw {
v, err := semver.NewVersion(r)
if err != nil {
t.Errorf("Error parsing version: %s", err)
}
vs[i] = v
}
sort.Sort(semver.Collection(vs))
Checking Version Constraints
Checking a version against version constraints is one of the most featureful
parts of the package.
c, err := semver.NewConstraint(">= 1.2.3")
if err != nil {
// Handle constraint not being parseable.
}
v, _ := semver.NewVersion("1.3")
if err != nil {
// Handle version not being parseable.
}
// Check if the version meets the constraints. The a variable will be true.
a := c.Check(v)
Basic Comparisons
There are two elements to the comparisons. First, a comparison string is a list
of comma separated and comparisons. These are then separated by || separated or
comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
greater than or equal to 4.2.3.
The basic comparisons are:
* `=`: equal (aliased to no operator)
* `!=`: not equal
* `>`: greater than
* `<`: less than
* `>=`: greater than or equal to
* `<=`: less than or equal to
Hyphen Range Comparisons
There are multiple methods to handle ranges and the first is hyphens ranges.
These look like:
* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
Wildcards In Comparisons
The `x`, `X`, and `*` characters can be used as a wildcard character. This works
for all comparison operators. When used on the `=` operator it falls
back to the pack level comparison (see tilde below). For example,
* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `>= 1.2.x` is equivalent to `>= 1.2.0`
* `<= 2.x` is equivalent to `<= 3`
* `*` is equivalent to `>= 0.0.0`
Tilde Range Comparisons (Patch)
The tilde (`~`) comparison operator is for patch level ranges when a minor
version is specified and major level changes when the minor number is missing.
For example,
* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
* `~1` is equivalent to `>= 1, < 2`
* `~2.3` is equivalent to `>= 2.3, < 2.4`
* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `~1.x` is equivalent to `>= 1, < 2`
Caret Range Comparisons (Major)
The caret (`^`) comparison operator is for major level changes. This is useful
when comparisons of API versions as a major change is API breaking. For example,
* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
* `^2.3` is equivalent to `>= 2.3, < 3`
* `^2.x` is equivalent to `>= 2.0.0, < 3`

# Sprig: Template functions for Go templates
[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
The Go language comes with a [built-in template
language](http://golang.org/pkg/text/template/), but not
very many template functions. This library provides a group of commonly
used template functions.
It is inspired by the template functions found in
[Twig](http://twig.sensiolabs.org/documentation) and also in various
JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
## Usage
Template developers can read the [Sprig function documentation](http://masterminds.github.io/sprig/) to
learn about the >100 template functions available.
For Go developers wishing to include Sprig as a library in their programs,
API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig), but
read on for standard usage.
### Load the Sprig library
To load the Sprig `FuncMap`:
```go
import (
"github.com/Masterminds/sprig"
"html/template"
)
// This example illustrates that the FuncMap *must* be set before the
// templates themselves are loaded.
tpl := template.Must(
template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
)
```
### Call the functions inside of templates
By convention, all functions are lowercase. This seems to follow the Go
idiom for template functions (as opposed to template methods, which are
TitleCase).
Example:
```
{{ "hello!" | upper | repeat 5 }}
```
Produces:
```
HELLO!HELLO!HELLO!HELLO!HELLO!
```
## Principles:
The following principles were used in deciding on which functions to add, and
determining how to implement them.
- Template functions should be used to build layout. Therefore, the following
types of operations are within the domain of template functions:
- Formatting
- Layout
- Simple type conversions
- Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
- Template functions should not return errors unless there is no way to print
a sensible value. For example, converting a string to an integer should not
produce an error if conversion fails. Instead, it should display a default
value that can be displayed.
- Simple math is necessary for grid layouts, pagers, and so on. Complex math
(anything other than arithmetic) should be done outside of templates.
- Template functions only deal with the data passed into them. They never retrieve
data from a source.
- Finally, do not override core Go template functions.

/*
Sprig: Template functions for Go.
This package contains a number of utility functions for working with data
inside of Go `html/template` and `text/template` files.
To add these functions, use the `template.Funcs()` method:
t := templates.New("foo").Funcs(sprig.FuncMap())
Note that you should add the function map before you parse any template files.
In several cases, Sprig reverses the order of arguments from the way they
appear in the standard library. This is to make it easier to pipe
arguments into functions.
See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.

goconfig [![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/Unknwon/goconfig)
========
[中文文档](README_ZH.md)
**IMPORTANT**
- This library is under bug fix only mode, which means no more features will be added.
- I'm continuing working on better Go code with a different library: [ini](https://github.com/go-ini/ini).
## About
Package goconfig is a easy-use, comments-support configuration file parser for the Go Programming Language, which provides a structure similar to what you would find on Microsoft Windows INI files.
The configuration file consists of sections, led by a `[section]` header and followed by `name:value` or `name=value` entries. Note that leading whitespace is removed from values. The optional values can contain format strings which refer to other values in the same section, or values in a special DEFAULT section. Comments are indicated by ";" or "#"; comments may begin anywhere on a single line.
## Features
- It simplified operation processes, easy to use and undersatnd; therefore, there are less chances to have errors.
- It uses exactly the same way to access a configuration file as you use Windows APIs, so you don't need to change your code style.
- It supports read recursion sections.
- It supports auto increment of key.
- It supports **READ** and **WRITE** configuration file with comments each section or key which all the other parsers don't support!!!!!!!
- It supports get value through type bool, float64, int, int64 and string, methods that start with "Must" means ignore errors and get zero-value if error occurs, or you can specify a default value.
- It's able to load multiple files to overwrite key values.
## Installation
go get github.com/unknwon/goconfig
## API Documentation
[Go Walker](http://gowalker.org/github.com/unknwon/goconfig).
## Example
Please see [conf.ini](testdata/conf.ini) as an example.
### Usage
- Function `LoadConfigFile` load file(s) depends on your situation, and return a variable with type `ConfigFile`.
- `GetValue` gives basic functionality of getting a value of given section and key.
- Methods like `Bool`, `Int`, `Int64` return corresponding type of values.
- Methods start with `Must` return corresponding type of values and returns zero-value of given type if something goes wrong.
- `SetValue` sets value to given section and key, and inserts somewhere if it does not exist.
- `DeleteKey` deletes by given section and key.
- Finally, `SaveConfigFile` saves your configuration to local file system.
- Use method `Reload` in case someone else modified your file(s).
- Methods contains `Comment` help you manipulate comments.
- `LoadFromReader` allows loading data without an intermediate file.
- `SaveConfigData` added, which writes configuration to an arbitrary writer.
- `ReloadData` allows to reload data from memory.
Note that you cannot mix in-memory configuration with on-disk configuration.
## More Information
- All characters are CASE SENSITIVE, BE CAREFUL!

goconfig [![Build Status](https://drone.io/github.com/Unknwon/goconfig/status.png)](https://drone.io/github.com/Unknwon/goconfig/latest) [![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/Unknwon/goconfig)
========
本库已被 [Go名库讲解](https://github.com/Unknwon/go-rock-libraries-showcases/tree/master/lectures/01-goconfig) 收录讲解,欢迎前往学习如何使用!
编码规范基于 [Go 编码规范](https://github.com/Unknwon/go-code-convention)
## 关于
goconfig 是一个易于使用支持注释的 Go 语言配置文件解析器该文件的书写格式和 Windows 下的 INI 文件一样
配置文件由形为 `[section]` 的节构成内部使用 `name:value` `name=value` 这样的键值对每行开头和尾部的空白符号都将被忽略如果未指定任何节则会默认放入名为 `DEFAULT` 的节当中可以使用 ; # 来作为注释的开头并可以放置于任意的单独一行中
## 特性
- 简化流程易于理解更少出错
- 提供与 Windows API 一模一样的操作方式
- 支持读取递归节
- 支持自增键名
- 支持对注释的 **** **** 操作其它所有解析器都不支持
- 可以直接返回 bool, float64, int, int64 string 类型的值如果使用 Must 开头的方法则一定会返回这个类型的一个值而不返回错误如果错误发生则会返回零值
- 支持加载多个文件来重写值
## 安装
go get github.com/Unknwon/goconfig
gopm get github.com/Unknwon/goconfig
## API 文档
[Go Walker](http://gowalker.org/github.com/Unknwon/goconfig).
## 示例
请查看 [conf.ini](testdata/conf.ini) 文件作为使用示例
### 用例
- 函数 `LoadConfigFile` 加载一个或多个文件然后返回一个类型为 `ConfigFile` 的变量
- `GetValue` 可以简单的获取某个值
- `Bool``Int``Int64` 这样的方法会直接返回指定类型的值
- `Must` 开头的方法不会返回错误但当错误发生时会返回零值
- `SetValue` 可以设置某个值
- `DeleteKey` 可以删除某个键
- 最后`SaveConfigFile` 可以保持您的配置到本地文件系统
- 使用方法 `Reload` 可以重载您的配置文件
## 更多信息
- 所有字符都是大小写敏感的

GoUtils
===========
[![Stability: Maintenance](https://masterminds.github.io/stability/maintenance.svg)](https://masterminds.github.io/stability/maintenance.html)
[![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils) [![Build Status](https://travis-ci.org/Masterminds/goutils.svg?branch=master)](https://travis-ci.org/Masterminds/goutils) [![Build status](https://ci.appveyor.com/api/projects/status/sc2b1ew0m7f0aiju?svg=true)](https://ci.appveyor.com/project/mattfarina/goutils)
GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
* WordUtils
* RandomStringUtils
* StringUtils (partial implementation)
## Installation
If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
go get github.com/Masterminds/goutils
If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
## Documentation
GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
## Usage
The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
package main
import (
"fmt"
"github.com/Masterminds/goutils"
)
func main() {
// EXAMPLE 1: A goutils function which returns no errors
fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
}
Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
package main
import (
"fmt"
"github.com/Masterminds/goutils"
)
func main() {
// EXAMPLE 2: A goutils function which returns an error
rand1, err1 := goutils.Random (-1, 0, 0, true, true)
if err1 != nil {
fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
} else {
fmt.Println(rand1)
}
}
## License
GoUtils is licensed under the Apache License, Version 2.0. Please check the LICENSE.txt file or visit http://www.apache.org/licenses/LICENSE-2.0 for a copy of the license.

Abbreviate abbreviates a string using ellipses. This will turn the string "Now is the time for all good men" into "Now is the time for..."

- If maxWidth is less than 4, return an illegal argument error.
- In no case will it return a string of length greater than maxWidth.

![Structured logging for golang](assets/title.png)
Package log implements a simple structured logging API inspired by Logrus, designed with centralization in mind. Read more on [Medium](https://medium.com/@tjholowaychuk/apex-log-e8d9627f4a9a#.rav8yhkud).
## Handlers
- __cli__ human-friendly CLI output
- __discard__ discards all logs
- __es__  Elasticsearch handler
- __graylog__ Graylog handler
- __json__  JSON output handler
- __kinesis__ AWS Kinesis handler
- __level__  level filter handler
- __logfmt__  logfmt plain-text formatter
- __memory__ in-memory handler for tests
- __multi__ fan-out to multiple handlers
- __papertrail__ Papertrail handler
- __text__  human-friendly colored output
- __delta__  outputs the delta between log calls and spinner

## Migration Guide from v2 -> v3
Version 3 adds several new, frequently requested features. To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code.
### `Token.Claims` is now an interface type
The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property.
The old example for parsing a token looked like this..
```go
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
}
```
is now directly mapped to...
```go
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
claims := token.Claims.(jwt.MapClaims)
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
}
```
`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type.
```go
type MyCustomClaims struct {
User string
*StandardClaims
}
if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
claims := token.Claims.(*MyCustomClaims)
fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
}
```
### `ParseFromRequest` has been moved
To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`.
`Extractors` do the work of picking the token string out of a request. The interface is simple and composable.
This simple parsing example:
```go
if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
}
```
is directly mapped to:
```go
if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
claims := token.Claims.(jwt.MapClaims)
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
}
```
There are several concrete `Extractor` types provided for your convenience:
* `HeaderExtractor` will search a list of headers until one contains content.
* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header
### RSA signing methods no longer accept `[]byte` keys
Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
```go
func keyLookupFunc(*Token) (interface{}, error) {
// Don't forget to validate the alg is what you expect:
if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
}
// Look up key
key, err := lookupPublicKey(token.Header["kid"])
if err != nil {
return nil, err
}
// Unpack key from PEM encoded PKCS8
return jwt.ParseRSAPublicKeyFromPEM(key)
}
```

# jwt-go
[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go)
[![GoDoc](https://godoc.org/github.com/dgrijalva/jwt-go?status.svg)](https://godoc.org/github.com/dgrijalva/jwt-go)
A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html)
**NEW VERSION COMING:** There have been a lot of improvements suggested since the version 3.0.0 released in 2016. I'm working now on cutting two different releases: 3.2.0 will contain any non-breaking changes or enhancements. 4.0.0 will follow shortly which will include breaking changes. See the 4.0.0 milestone to get an idea of what's coming. If you have other ideas, or would like to participate in 4.0.0, now's the time. If you depend on this library and don't want to be interrupted, I recommend you use your dependency mangement tool to pin to version 3.
**SECURITY NOTICE:** Some older versions of Go have a security issue in the cryotp/elliptic. Recommendation is to upgrade to at least 1.8.3. See issue #216 for more detail.
**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage. See the examples provided.
## What the heck is a JWT?
JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way.
The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used.
The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
## What's in the box?
This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
## Examples
See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac)
* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac)
* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples)
## Extensions
This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.
Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
## Compliance
This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences:
* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
## Project Status & Versioning
This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users. You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v3`. It will do the right thing WRT semantic versioning.
**BREAKING CHANGES:***
* Version 3.0.0 includes _a lot_ of changes from the 2.x line, including a few that break the API. We've tried to break as few things as possible, so there should just be a few type signature changes. A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code.
## Usage Tips
### Signing vs Encryption
A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
* The author of the token was in the possession of the signing secret
* The data has not been modified since it was signed
It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
### Choosing a Signing Method
There are several signing methods available, and you should probably take the time to learn about the various options before choosing one. The principal design decision is most likely going to be symmetric vs asymmetric.
Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
### Signing Methods and Key Types
Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
* The [HMAC signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
* The [RSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
* The [ECDSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
### JWT and OAuth
It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.

## `jwt-go` Version History
#### 3.2.0
* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
#### 3.1.0
* Improvements to `jwt` command line tool
* Added `SkipClaimsValidation` option to `Parser`
* Documentation updates
#### 3.0.0
* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
* Dropped support for `[]byte` keys when using RSA signing methods. This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`. The default value is type `MapClaims`, which is an alias to `map[string]interface{}`. This makes it possible to use a custom type when decoding claims.
* Other Additions and Changes
* Added `Claims` interface type to allow users to decode the claims into a custom type
* Added `ParseWithClaims`, which takes a third argument of type `Claims`. Use this function instead of `Parse` if you have a custom type you'd like to decode into.
* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests. Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
* Added several new, more specific, validation errors to error type bitmask
* Moved examples from README to executable example files
* Signing method registry is now thread safe
* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
#### 2.7.0
This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
* Error text for expired tokens includes how long it's been expired
* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
* Documentation updates
#### 2.6.0
* Exposed inner error within ValidationError
* Fixed validation errors when using UseJSONNumber flag
* Added several unit tests
#### 2.5.0
* Added support for signing method none. You shouldn't use this. The API tries to make this clear.
* Updated/fixed some documentation
* Added more helpful error message when trying to parse tokens that begin with `BEARER `
#### 2.4.0
* Added new type, Parser, to allow for configuration of various parsing parameters
* You can now specify a list of valid signing methods. Anything outside this set will be rejected.
* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
* Fixed some bugs with ECDSA parsing
#### 2.3.0
* Added support for ECDSA signing methods
* Added support for RSA PSS signing methods (requires go v1.4)
#### 2.2.0
* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`. Result will now be the parsed token and an error, instead of a panic.
#### 2.1.0
Backwards compatible API change that was missed in 2.0.0.
* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
#### 2.0.0
There were two major reasons for breaking backwards compatibility with this update. The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change.
The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
* **Compatibility Breaking Changes**
* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
* `KeyFunc` now returns `interface{}` instead of `[]byte`
* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodHS256`
* Added public package global `SigningMethodHS384`
* Added public package global `SigningMethodHS512`
* Renamed type `SigningMethodRS256` to `SigningMethodRSA`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodRS256`
* Added public package global `SigningMethodRS384`
* Added public package global `SigningMethodRS512`
* Moved sample private key for HMAC tests from an inline value to a file on disk. Value is unchanged.
* Refactored the RSA implementation to be easier to read
* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
#### 1.0.2
* Fixed bug in parsing public keys from certificates
* Added more tests around the parsing of keys for RS256
* Code refactoring in RS256 implementation. No functional changes
#### 1.0.1
* Fixed panic if RS256 signing method was passed an invalid key
#### 1.0.0
* First versioned release
* API stabilized
* Supports creating, signing, parsing, and validating JWT tokens
* Supports RS256 and HS256 signing methods

// In computer science, a list or sequence is an abstract data type that represents an ordered sequence of values, where the same value may occur more than once. An instance of a list is a computer representation of the mathematical concept of a finite sequence; the (potentially) infinite analog of a list is a stream. Lists are a basic example of containers, as they contain other values. If the same value occurs multiple times, each occurrence is considered a distinct item.
