Git LFS support v2 (#122)
* Import github.com/git-lfs/lfs-test-server as lfs module base Imported commit is 3968aac269a77b73924649b9412ae03f7ccd3198 Removed: Dockerfile CONTRIBUTING.md mgmt* script/ vendor/ kvlogger.go .dockerignore .gitignore README.md * Remove config, add JWT support from github.com/mgit-at/lfs-test-server Imported commit f0cdcc5a01599c5a955dc1bbf683bb4acecdba83 * Add LFS settings * Add LFS meta object model * Add LFS routes and initialization * Import github.com/dgrijalva/jwt-go into vendor/ * Adapt LFS module: handlers, routing, meta store * Move LFS routes to /user/repo/info/lfs/* * Add request header checks to LFS BatchHandler / PostHandler * Implement LFS basic authentication * Rework JWT secret generation / load * Implement LFS SSH token authentication with JWT Specification: https://github.com/github/git-lfs/tree/master/docs/api * Integrate LFS settings into install process * Remove LFS objects when repository is deleted Only removes objects from content store when deleted repo is the only referencing repository * Make LFS module stateless Fixes bug where LFS would not work after installation without restarting Gitea * Change 500 'Internal Server Error' to 400 'Bad Request' * Change sql query to xorm call * Remove unneeded type from LFS module * Change internal imports to code.gitea.io/gitea/ * Add Gitea authors copyright * Change basic auth realm to "gitea-lfs" * Add unique indexes to LFS model * Use xorm count function in LFS check on repository delete * Return io.ReadCloser from content store and close after usage * Add LFS info to runWeb() * Export LFS content store base path * LFS file download from UI * Work around git-lfs client issue with unauthenticated requests Returning a dummy Authorization header for unauthenticated requests lets git-lfs client skip asking for auth credentials See: https://github.com/github/git-lfs/issues/1088 * Fix unauthenticated UI downloads from public repositories * Authentication check order, Finish LFS file view logic * Ignore LFS hooks if installed for current OS user Fixes Gitea UI actions for repositories tracking LFS files. Checks for minimum needed git version by parsing the semantic version string. * Hide LFS metafile diff from commit view, marking as binary * Show LFS notice if file in commit view is tracked * Add notbefore/nbf JWT claim * Correct lint suggestions - comments for structs and functions - Add comments to LFS model - Function comment for GetRandomBytesAsBase64 - LFS server function comments and lint variable suggestion * Move secret generation code out of conditional Ensures no LFS code may run with an empty secret * Do not hand out JWT tokens if LFS server support is disabled

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)
|
||||
}
|
||||
```

**BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes 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.
|
||||
|
||||
**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected. There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API. In the short term, please make sure your implementation verifies the `alg` is what you expect.
|
||||
|
||||
|
||||
## 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.v2`. It will do the right thing WRT semantic versioning.
|
||||
|
||||
## 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.
|
||||
|
||||
### 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.
|
||||
|
||||
## More
|
||||
|
||||
Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
|
||||
|
||||
The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in to documentation.

## `jwt-go` Version History
|
||||
|
||||
#### 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
