From bba77163ffa1a3d1fcd97f562dd1b92ffed20ac1 Mon Sep 17 00:00:00 2001 From: Djordje Lukic Date: Wed, 27 Jul 2022 14:24:34 +0200 Subject: [PATCH 1/2] c8d: Make build and buildx work MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Only use the image exporter in build if we don't use containerd Without this "docker build" fails with: Error response from daemon: exporter "image" could not be found - let buildx know we support containerd snapshotter - Pass the current snapshotter to the buildkit worker If buildkit uses a different snapshotter we can't list the images any more because we can't find the snapshot. builder/builder-next: make ContainerdWorker a minimal wrapper Note that this makes "Worker" a public field, so technically one could overwrite it. builder-next: reenable runc executor Currently, without special CNI config the builder would only create host network containers that is a security issue. Using runc directly instead of shim is faster as well as builder doesn’t need anything from shim. The overhead of setting up network sandbox is much slower of course. builder/builder-next: simplify options handling Trying to simplify the logic; - Use an early return if multiple outputs are provided - Only construct the list of tags if we're using an image (or moby) exporter - Combine some logic for snapshotter and non-snapshotter handling Create a constant for the moby exporter Pass a context when creating a router The context has a 10 seconds timeout which should be more than enough to get the answer from containerd.

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](https://datatracker.ietf.org/doc/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 [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) 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. + +## Installation Guidelines + +1. To install the jwt package, you first need to have [Go](https://go.dev/doc/install) installed, then you can use the command below to add `jwt-go` as a dependency in your Go program. + +```sh +go get -u github.com/golang-jwt/jwt/v4 +``` + +2. Import it in your code: + +```go +import "github.com/golang-jwt/jwt/v4" +``` + +## Examples + +See [the project documentation](https://pkg.go.dev/github.com/golang-jwt/jwt/v4) for examples of usage: + +* [Simple example of parsing and validating a token](https://pkg.go.dev/github.com/golang-jwt/jwt#example-Parse-Hmac) +* [Simple example of building and signing a token](https://pkg.go.dev/github.com/golang-jwt/jwt#example-New-Hmac) +* [Directory of Examples](https://pkg.go.dev/github.com/golang-jwt/jwt#pkg-examples) + +## Extensions + +This library publishes all the necessary components for adding your own signing methods or key functions. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod` or provide a `jwt.Keyfunc`. + +A common use case would be integrating with different 3rd party signature providers, like key management services from various cloud providers or Hardware Security Modules (HSMs) or to implement additional standards. + +| Extension | Purpose | Repo | +| --------- | -------------------------------------------------------------------------------------------------------- | ------------------------------------------ | +| GCP | Integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS) | https://github.com/someone1/gcp-jwt-go | +| AWS | Integrates with AWS Key Management Service, KMS | https://github.com/matelang/jwt-go-aws-kms | +| JWKS | Provides support for JWKS ([RFC 7517](https://datatracker.ietf.org/doc/html/rfc7517)) as a `jwt.Keyfunc` | https://github.com/MicahParks/keyfunc | + +*Disclaimer*: Unless otherwise specified, these integrations are maintained by third parties and should not be considered as a primary offer by any of the mentioned cloud providers + +## Compliance + +This library was last reviewed to comply with [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) dated May 2015 with a few notable differences: + +* In order to protect against accidental use of [Unsecured JWTs](https://datatracker.ietf.org/doc/html/rfc7519#section-6), 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 `main`. Periodically, versions will be tagged from `main`. You can find all the releases on [the project releases page](https://github.com/golang-jwt/jwt/releases). + +**BREAKING 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://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation +* The [RSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation +* The [ECDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation +* The [EdDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodEd25519) (`Ed25519`) expect `ed25519.PrivateKey` for signing and `ed25519.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. + +### Troubleshooting + +This library uses descriptive error messages whenever possible. If you are not getting the expected result, have a look at the errors. The most common place people get stuck is providing the correct type of key to the parser. See the above section on signing methods and key types. + +## More + +Documentation can be found [on pkg.go.dev](https://pkg.go.dev/github.com/golang-jwt/jwt). + +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.

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 diff --git a/vendor/github.com/golang-jwt/jwt/v4/claims.go b/vendor/github.com/golang-jwt/jwt/v4/claims.go new file mode 100644 index 0000000000000..9d95cad2bf270 --- /dev/null +++ b/vendor/github.com/golang-jwt/jwt/v4/claims.go @@ -0,0 +1,273 @@ +package jwt + +import ( + "crypto/subtle" + "fmt" + "time" +) + +// Claims must just have a Valid method that determines +// if the token is invalid for any supported reason +type Claims interface { + Valid() error +} + +// RegisteredClaims are a structured version of the JWT Claims Set, +// restricted to Registered Claim Names, as referenced at +// https://datatracker.ietf.org/doc/html/rfc7519#section-4.1 +// +// This type can be used on its own, but then additional private and +// public claims embedded in the JWT will not be parsed.
