1# Migration Guide (v5.0.0)
2
3Version `v5` contains a major rework of core functionalities in the `jwt-go`
4library. This includes support for several validation options as well as a
5re-design of the `Claims` interface. Lastly, we reworked how errors work under
6the hood, which should provide a better overall developer experience.
7
8Starting from [v5.0.0](https://github.com/golang-jwt/jwt/releases/tag/v5.0.0),
9the import path will be:
10
11 "github.com/golang-jwt/jwt/v5"
12
13For most users, changing the import path *should* suffice. However, since we
14intentionally changed and cleaned some of the public API, existing programs
15might need to be updated. The following sections describe significant changes
16and corresponding updates for existing programs.
17
18## Parsing and Validation Options
19
20Under the hood, a new `Validator` struct takes care of validating the claims. A
21long awaited feature has been the option to fine-tune the validation of tokens.
22This is now possible with several `ParserOption` functions that can be appended
23to most `Parse` functions, such as `ParseWithClaims`. The most important options
24and changes are:
25 * Added `WithLeeway` to support specifying the leeway that is allowed when
26 validating time-based claims, such as `exp` or `nbf`.
27 * Changed default behavior to not check the `iat` claim. Usage of this claim
28 is OPTIONAL according to the JWT RFC. The claim itself is also purely
29 informational according to the RFC, so a strict validation failure is not
30 recommended. If you want to check for sensible values in these claims,
31 please use the `WithIssuedAt` parser option.
32 * Added `WithAudience`, `WithSubject` and `WithIssuer` to support checking for
33 expected `aud`, `sub` and `iss`.
34 * Added `WithStrictDecoding` and `WithPaddingAllowed` options to allow
35 previously global settings to enable base64 strict encoding and the parsing
36 of base64 strings with padding. The latter is strictly speaking against the
37 standard, but unfortunately some of the major identity providers issue some
38 of these incorrect tokens. Both options are disabled by default.
39
40## Changes to the `Claims` interface
41
42### Complete Restructuring
43
44Previously, the claims interface was satisfied with an implementation of a
45`Valid() error` function. This had several issues:
46 * The different claim types (struct claims, map claims, etc.) then contained
47 similar (but not 100 % identical) code of how this validation was done. This
48 lead to a lot of (almost) duplicate code and was hard to maintain
49 * It was not really semantically close to what a "claim" (or a set of claims)
50 really is; which is a list of defined key/value pairs with a certain
51 semantic meaning.
52
53Since all the validation functionality is now extracted into the validator, all
54`VerifyXXX` and `Valid` functions have been removed from the `Claims` interface.
55Instead, the interface now represents a list of getters to retrieve values with
56a specific meaning. This allows us to completely decouple the validation logic
57with the underlying storage representation of the claim, which could be a
58struct, a map or even something stored in a database.
59
60```go
61type Claims interface {
62 GetExpirationTime() (*NumericDate, error)
63 GetIssuedAt() (*NumericDate, error)
64 GetNotBefore() (*NumericDate, error)
65 GetIssuer() (string, error)
66 GetSubject() (string, error)
67 GetAudience() (ClaimStrings, error)
68}
69```
70
71Users that previously directly called the `Valid` function on their claims,
72e.g., to perform validation independently of parsing/verifying a token, can now
73use the `jwt.NewValidator` function to create a `Validator` independently of the
74`Parser`.
75
76```go
77var v = jwt.NewValidator(jwt.WithLeeway(5*time.Second))
78v.Validate(myClaims)
79```
80
81### Supported Claim Types and Removal of `StandardClaims`
82
83The two standard claim types supported by this library, `MapClaims` and
84`RegisteredClaims` both implement the necessary functions of this interface. The
85old `StandardClaims` struct, which has already been deprecated in `v4` is now
86removed.
87
88Users using custom claims, in most cases, will not experience any changes in the
89behavior as long as they embedded `RegisteredClaims`. If they created a new
90claim type from scratch, they now need to implemented the proper getter
91functions.
92
93### Migrating Application Specific Logic of the old `Valid`
94
95Previously, users could override the `Valid` method in a custom claim, for
96example to extend the validation with application-specific claims. However, this
97was always very dangerous, since once could easily disable the standard
98validation and signature checking.
99
100In order to avoid that, while still supporting the use-case, a new
101`ClaimsValidator` interface has been introduced. This interface consists of the
102`Validate() error` function. If the validator sees, that a `Claims` struct
103implements this interface, the errors returned to the `Validate` function will
104be *appended* to the regular standard validation. It is not possible to disable
105the standard validation anymore (even only by accident).
106
107Usage examples can be found in [example_test.go](./example_test.go), to build
108claims structs like the following.
109
110```go
111// MyCustomClaims includes all registered claims, plus Foo.
112type MyCustomClaims struct {
113 Foo string `json:"foo"`
114 jwt.RegisteredClaims
115}
116
117// Validate can be used to execute additional application-specific claims
118// validation.
119func (m MyCustomClaims) Validate() error {
120 if m.Foo != "bar" {
121 return errors.New("must be foobar")
122 }
123
124 return nil
125}
126```
127
128## Changes to the `Token` and `Parser` struct
129
130The previously global functions `DecodeSegment` and `EncodeSegment` were moved
131to the `Parser` and `Token` struct respectively. This will allow us in the
132future to configure the behavior of these two based on options supplied on the
133parser or the token (creation). This also removes two previously global
134variables and moves them to parser options `WithStrictDecoding` and
135`WithPaddingAllowed`.
136
137In order to do that, we had to adjust the way signing methods work. Previously
138they were given a base64 encoded signature in `Verify` and were expected to
139return a base64 encoded version of the signature in `Sign`, both as a `string`.
140However, this made it necessary to have `DecodeSegment` and `EncodeSegment`
141global and was a less than perfect design because we were repeating
142encoding/decoding steps for all signing methods. Now, `Sign` and `Verify`
143operate on a decoded signature as a `[]byte`, which feels more natural for a
144cryptographic operation anyway. Lastly, `Parse` and `SignedString` take care of
145the final encoding/decoding part.
146
147In addition to that, we also changed the `Signature` field on `Token` from a
148`string` to `[]byte` and this is also now populated with the decoded form. This
149is also more consistent, because the other parts of the JWT, mainly `Header` and
150`Claims` were already stored in decoded form in `Token`. Only the signature was
151stored in base64 encoded form, which was redundant with the information in the
152`Raw` field, which contains the complete token as base64.
153
154```go
155type Token struct {
156 Raw string // Raw contains the raw token
157 Method SigningMethod // Method is the signing method used or to be used
158 Header map[string]interface{} // Header is the first segment of the token in decoded form
159 Claims Claims // Claims is the second segment of the token in decoded form
160 Signature []byte // Signature is the third segment of the token in decoded form
161 Valid bool // Valid specifies if the token is valid
162}
163```
164
165Most (if not all) of these changes should not impact the normal usage of this
166library. Only users directly accessing the `Signature` field as well as
167developers of custom signing methods should be affected.
168
169# Migration Guide (v4.0.0)
170
171Starting from [v4.0.0](https://github.com/golang-jwt/jwt/releases/tag/v4.0.0),
172the import path will be:
173
174 "github.com/golang-jwt/jwt/v4"
175
176The `/v4` version will be backwards compatible with existing `v3.x.y` tags in
177this repo, as well as `github.com/dgrijalva/jwt-go`. For most users this should
178be a drop-in replacement, if you're having troubles migrating, please open an
179issue.
180
181You can replace all occurrences of `github.com/dgrijalva/jwt-go` or
182`github.com/golang-jwt/jwt` with `github.com/golang-jwt/jwt/v4`, either manually
183or by using tools such as `sed` or `gofmt`.
184
185And then you'd typically run:
186
187```
188go get github.com/golang-jwt/jwt/v4
189go mod tidy
190```
191
192# Older releases (before v3.2.0)

9implementation of [JSON Web
10Tokens](https://datatracker.ietf.org/doc/html/rfc7519).
11
12Starting with [v4.0.0](https://github.com/golang-jwt/jwt/releases/tag/v4.0.0)
13this project adds Go module support, but maintains backwards compatibility with
14older `v3.x.y` tags and upstream `github.com/dgrijalva/jwt-go`. See the
15[`MIGRATION_GUIDE.md`](./MIGRATION_GUIDE.md) for more information. Version
16v5.0.0 introduces major improvements to the validation of tokens, but is not
17entirely backwards compatible.
18
19> After the original author of the library suggested migrating the maintenance
20> of `jwt-go`, a dedicated team of open source maintainers decided to clone the
21> existing library into this repository. See
22> [dgrijalva/jwt-go#462](https://github.com/dgrijalva/jwt-go/issues/462) for a
23> detailed discussion on this topic.
24
25
26**SECURITY NOTICE:** Some older versions of Go have a security issue in the
27crypto/elliptic. Recommendation is to upgrade to at least 1.15 See issue
28[dgrijalva/jwt-go#216](https://github.com/dgrijalva/jwt-go/issues/216) for more
29detail.
30
31**SECURITY NOTICE:** It's important that you [validate the `alg` presented is
32what you
33expect](https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/).
34This library attempts to make it easy to do the right thing by requiring key
35types match the expected alg, but you should take the extra step to verify it in
36your usage. See the examples provided.
37
38### Supported Go versions
39
40Our support of Go versions is aligned with Go's [version release
41policy](https://golang.org/doc/devel/release#policy). So we will support a major
42version of Go until there are two newer major releases. We no longer support
43building jwt-go with unsupported Go versions, as these contain security
44vulnerabilities which will not be fixed.
45
46## What the heck is a JWT?
47
48JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web
49Tokens.
50
51In short, it's a signed JSON object that does something useful (for example,
52authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is
53made of three parts, separated by `.`'s. The first two parts are JSON objects,
54that have been [base64url](https://datatracker.ietf.org/doc/html/rfc4648)
55encoded. The last part is the signature, encoded the same way.
56
57The first part is called the header. It contains the necessary information for
58verifying the last part, the signature. For example, which encryption method
59was used for signing and what key was used.
60
61The part in the middle is the interesting bit. It's called the Claims and
62contains the actual stuff you care about. Refer to [RFC
637519](https://datatracker.ietf.org/doc/html/rfc7519) for information about
64reserved keys and the proper way to add your own.
65
66## What's in the box?
67
68This library supports the parsing and verification as well as the generation and
69signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA,
70RSA-PSS, and ECDSA, though hooks are present for adding your own.
71
72## Installation Guidelines
73
741. To install the jwt package, you first need to have
75 [Go](https://go.dev/doc/install) installed, then you can use the command
76 below to add `jwt-go` as a dependency in your Go program.
77
78```sh
79go get -u github.com/golang-jwt/jwt/v5
80```
81
822. Import it in your code:
83
84```go
85import "github.com/golang-jwt/jwt/v5"
86```
87
88## Usage
89
90A detailed usage guide, including how to sign and verify tokens can be found on
91our [documentation website](https://golang-jwt.github.io/jwt/usage/create/).
92
93## Examples
94
95See [the project documentation](https://pkg.go.dev/github.com/golang-jwt/jwt/v5)
96for examples of usage:
97
98* [Simple example of parsing and validating a
99 token](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#example-Parse-Hmac)
100* [Simple example of building and signing a
101 token](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#example-New-Hmac)
102* [Directory of
103 Examples](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#pkg-examples)
104
105## Compliance
106
107This library was last reviewed to comply with [RFC
1087519](https://datatracker.ietf.org/doc/html/rfc7519) dated May 2015 with a few
109notable differences:
110
111* In order to protect against accidental use of [Unsecured
112 JWTs](https://datatracker.ietf.org/doc/html/rfc7519#section-6), tokens using
113 `alg=none` will only be accepted if the constant
114 `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
115
116## Project Status & Versioning
117
118This library is considered production ready. Feedback and feature requests are
119appreciated. The API should be considered stable. There should be very few
120backwards-incompatible changes outside of major version updates (and only with
121good reason).
122
123This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull
124requests will land on `main`. Periodically, versions will be tagged from
125`main`. You can find all the releases on [the project releases
126page](https://github.com/golang-jwt/jwt/releases).
127
128**BREAKING CHANGES:*** A full list of breaking changes is available in
129`VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating
130your code.
131
132## Extensions
133
134This library publishes all the necessary components for adding your own signing
135methods or key functions. Simply implement the `SigningMethod` interface and
136register a factory method using `RegisterSigningMethod` or provide a
137`jwt.Keyfunc`.
138
139A common use case would be integrating with different 3rd party signature
140providers, like key management services from various cloud providers or Hardware
141Security Modules (HSMs) or to implement additional standards.
142
143| Extension | Purpose | Repo |
144| --------- | -------------------------------------------------------------------------------------------------------- | ------------------------------------------ |
145| GCP | Integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS) | https://github.com/someone1/gcp-jwt-go |
146| AWS | Integrates with AWS Key Management Service, KMS | https://github.com/matelang/jwt-go-aws-kms |
147| JWKS | Provides support for JWKS ([RFC 7517](https://datatracker.ietf.org/doc/html/rfc7517)) as a `jwt.Keyfunc` | https://github.com/MicahParks/keyfunc |
148
149*Disclaimer*: Unless otherwise specified, these integrations are maintained by
150third parties and should not be considered as a primary offer by any of the
151mentioned cloud providers

1# `jwt-go` Version History
2
3The following version history is kept for historic purposes. To retrieve the current changes of each version, please refer to the change-log of the specific release versions on https://github.com/golang-jwt/jwt/releases.
4
5## 4.0.0
6
7* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`.
8
9## 3.2.2
10
11* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)).
12* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)).
13* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)).
14* Optimized allocations ([#33](https://github.com/golang-jwt/jwt/pull/33)).
15
16## 3.2.1
17
18* **Import Path Change**: See MIGRATION_GUIDE.md for tips on updating your code
19 * Changed the import path from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`
20* Fixed type confusing issue between `string` and `[]string` in `VerifyAudience` ([#12](https://github.com/golang-jwt/jwt/pull/12)). This fixes CVE-2020-26160
21
22#### 3.2.0
23
24* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
25* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
26* 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.
27* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
28
29#### 3.1.0
30
31* Improvements to `jwt` command line tool
32* Added `SkipClaimsValidation` option to `Parser`
33* Documentation updates
34
35#### 3.0.0
36
37* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
38 * 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.
39 * `ParseFromRequest` has been moved to `request` subpackage and usage has changed
40 * 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.
41* Other Additions and Changes
42 * Added `Claims` interface type to allow users to decode the claims into a custom type
43 * 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.
44 * Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
45 * Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
46 * Added new interface type `Extractor`, which is used for extracting JWT strings from http requests. Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
47 * Added several new, more specific, validation errors to error type bitmask
48 * Moved examples from README to executable example files
49 * Signing method registry is now thread safe
50 * 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)
51
52#### 2.7.0
53
54This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
55
56* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
57* Error text for expired tokens includes how long it's been expired
58* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
59* Documentation updates
60
61#### 2.6.0
62
63* Exposed inner error within ValidationError
64* Fixed validation errors when using UseJSONNumber flag
65* Added several unit tests
66
67#### 2.5.0
68
69* Added support for signing method none. You shouldn't use this. The API tries to make this clear.
70* Updated/fixed some documentation
71* Added more helpful error message when trying to parse tokens that begin with `BEARER `
72
73#### 2.4.0
74
75* Added new type, Parser, to allow for configuration of various parsing parameters
76 * You can now specify a list of valid signing methods. Anything outside this set will be rejected.
77 * You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
78* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
79* Fixed some bugs with ECDSA parsing
80
81#### 2.3.0
82
83* Added support for ECDSA signing methods
84* Added support for RSA PSS signing methods (requires go v1.4)
85
86#### 2.2.0
87
88* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`. Result will now be the parsed token and an error, instead of a panic.
89
90#### 2.1.0
91
92Backwards compatible API change that was missed in 2.0.0.
93
94* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
95
96#### 2.0.0
97
98There 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.
99
100The 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`.
101
102It 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`.
103
104* **Compatibility Breaking Changes**
105 * `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
106 * `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
107 * `KeyFunc` now returns `interface{}` instead of `[]byte`
108 * `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
109 * `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
110* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`. Specific sizes are now just instances of this type.
111 * Added public package global `SigningMethodHS256`
112 * Added public package global `SigningMethodHS384`
113 * Added public package global `SigningMethodHS512`
114* Renamed type `SigningMethodRS256` to `SigningMethodRSA`. Specific sizes are now just instances of this type.
115 * Added public package global `SigningMethodRS256`
116 * Added public package global `SigningMethodRS384`
117 * Added public package global `SigningMethodRS512`
118* Moved sample private key for HMAC tests from an inline value to a file on disk. Value is unchanged.
119* Refactored the RSA implementation to be easier to read
120* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
121
122## 1.0.2
123
124* Fixed bug in parsing public keys from certificates
125* Added more tests around the parsing of keys for RS256
126* Code refactoring in RS256 implementation. No functional changes
127
128## 1.0.1
129
130* Fixed panic if RS256 signing method was passed an invalid key
131
132## 1.0.0
133
134* First versioned release
135* API stabilized
136* Supports creating, signing, parsing, and validating JWT tokens
137* Supports RS256 and HS256 signing methods
