Changes
=======

v1.2.7 26 Sep 2021
[New features]
  * `jwt.InferAlgorithmFromKey()` option is now available to "guess"
    the algorithm used to verify the JWS signature on a JWT using
    a JWKS (key set). This allows you to match JWKs that do not have
    the `alg` field populated.

    We understand that some providers do not provide the `alg` field,
    which is a nuisance to users. But from a purely security minded PoV,
    we don't think that this "try until something works" approach is a
    good one, even if there are no known exploits. This is why the
    default `jwt.Parse` mechanism is unchanged, and an explicit option
    has been added.

  * Types `jwt.KeySetProvider` and `jwk.KeySetProviderFunc` have been
    added. Along with `jwt.WithKeySetProvider()` option, `jwt.Parse`
    can now choose the `jwk.Set` to use for signature verification
    dynamically using the UNVERFIEID token as a clue.

    You should NOT trust the token information too much. For example,
    DO NOT directly use values from the token as verificatin parameters
    (such as the signature algorithm)

  * `jwt.WithValidator()` has been added to allow users pass in aribtrary
    validation code to the `jwt.Validate()` method.

    It is also now possible to pass in a `context.Context` object to
    `jwt.Validate()` using `jwt.WithContext()` option.

[Miscellaneous]
  * Make the error messages when `jwt.ParseRequest` fails a bit better.
  * Moved around documentation within the repository
  * Validation logic for `jwt.Validate()` has been refactored to use the
    new `jwt.Validator` mechanism

v1.2.6 24 Aug 2021
[New features]
  * Support `crypto.Signer` keys for RSA, ECDSA, and EdDSA family
    of signatures in `jws.Sign`
[Miscellaneous]
  * `jwx.GuessFormat()` now requires the presense of both `payload` and
    `signatures` keys for it to guess that a JSON object is a JWS message.
  * Slightly enhance `jwt.Parse()` performance.

v1.2.5 04 Aug 2021
[New features]
  * Implement RFC7797. The value of the header field `b64` changes
    how the payload is treated in JWS
  * Implement detached payloads for JWS
  * Implement (jwk.AutoRefresh).ErrorSink() to register a channel
    where you can receive errors from fetches and parses that occur during
    JWK(s) retrieval.

v1.2.4 15 Jul 2021
[Bug fixes]
  * We had the same off-by-one in another place and jumped the gun on
    releasing a new version. At least we were making mistakes uniformally :/
    `(jwk.Set).Remove` should finally be fixed.

[New features]
  * `(jwk.Set).Clone()` has been added.

v1.2.3 15 Jul 2021
[Bug fixes]
  * jwk.Set incorrectly removed 2 elements instead of one.

[Miscellaneous]
  * github.com/goccy/go-json has been upgraded to v0.7.4

v1.2.2 13 Jul 2021
[Deprecation notice]
  * `(jwe.Message).Decrypt()` will be removed from the API upon the next
    major release.

[Bug Fixes]
  * `jwe.Decrypt` and `(jwe.Message).Decrypt()` failed to decrypt even
    with the correct message contents when used along with `jwe.RegisterCustomField`

[New features]
  JWX
  * Add GuessFormat() function to guess what the payload is.

  JWT
  * Options `jwt.WithMinDelta()`, `jwt.WithMaxDelta()` have been added.
    These can be used to compare time-based fields in the JWT object.
  * Option `jwt.WithRequiredClaim()` has been added. This can be used
    to check that JWT contains the given claim.
  * `jwt.Parse` now understands payloads that have been encrypted _and_ signed.
    This is more in line with the RFC than the previous implementation, but
    due to the fact that it requires a couple of extra unmarshaling, it may
    add some amount of overhead.
  * `jwt.Serializer` has been added as an easy wrapper to perform multiple
     levels of serializations (e.g. apply JWS, then JWE)

  JWE
  * Option `jwe.WithMessage()` has been added. This allows the user to
    obtain both the decrypted payload _and_ the raw `*jwe.Message` in one
    go when `jwe.Decrypt()` is called
  * Option `jwe.WithPostParser()`, along with `jwe.PostParser` and `jwe.PostParseFunc`
    has been added. This allows advanced users to hook into the `jwe.Decrypt()`
    process. The hook is called right after the JWE message has been parsed,
    but before the actual decryption has taken place.
  * `(jwe.Message).Decrypt()` has been marked for deprecation in a next major release.

  JWS
  * Option `jwe.WithMessage()` has been added. This allows the user to
    obtain both the verified payload _and_ the raw `*jws.Message` in one
    go when `jws.Verify()` is called
  * Options to `jws.Sign()` are not of type `jws.SignOption`. There should be
    no user-visible effects unless you were storing these somewhere.

v1.2.1 02 Jun 2021
[New features]
  * Option `jwt.WithTypedClaim()` and `jwk.WithTypedField()` have been added.
    They allow a per-object custom conversion from their JSON representation
    to a Go object, much like `RegisterCustomField`.

    The difference is that whereas `RegisterCustomField` has global effect,
    these typed fields only take effect in the call where the option was
    explicitly passed.

    `jws` and `jwe` does not have these options because
    (1) JWS and JWE messages don't generally carry much in terms of custom data
    (2) This requires changes in function signatures.

    Only use these options when you absolutely need to. While it is a powerful
    tool, they do have many caveats, and abusing these features will have
    negative effects. See the documentation for details

v1.2.0 30 Apr 2021

This is a security fix release with minor incompatibilities from earlier version
with regards to the behavior of `jwt.Verify()` function

[Security Fix]
  * `jwt.Verify()` had improperly used the `"alg"` header from the JWS message
    when `jwt.WithKeySet()` option was used (potentially allowing exploits
    described in https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/.
    This has been fixed by ONLY trusting the keys that you provide and
    using the `"alg"` header from the keys themselves. (#375, #381)

    As a side effect, `jwt.WithKeySet()` requires that all applicable keys
    to contain a valid `"alg"` header. Without this we cannot safely choose a key to use,
    and hence verification will fail.

    The requirement for the `"alg"` header on keys is an INCOMPATIBLE behavior.
    This may break existing code, if the key does not already have an `"alg"` header.

[New features]
  * `jwt.Settings()` and `jwt.WithFlattenAudience(bool)` has been added
    to control how the "aud" claim is serialized into JSON. When this
    is enabled, all JWTs with a single "aud" claim will serialize
    the field as a single string, instead of an array of strings with
    a single element, i.e.:

    // jwt.WithFlattenAudience(true)
    {"aud": "foo"}

    // jwt.WithFlattenAudience(false)
    {"aud": ["foo"]}

    This setting has a global effect.

[Buf fixes]
  * jwt.Validate now returns true if the value in `nbf` field is exactly
    the same as what the clock returns (e.g. token.nbf == time.Now())

v1.1.7 02 Apr 2021
[New features]
  * `jwk.New` `jwk.Parse`, `jwk.ParseKey` can now take a Certificate in
    ASN.1 DER format in PEM encoding to create a JWK.

[Bug fixes]
  * Protect `jwk.New()` from invalid RSA/ECDSA keys (#360, #361)

[Miscellaneous]
  * Removed "internal/blackmagic" and separated it to its own repository.
  * Removed unused "marshal proxy" objects in jwt
  * Added FAQ in `jwt` package

v1.1.6 28 Mar 2021
[Bug fixes]
  * When an object (e.g. JWT) has a null value and `AsMap()` is called,
    `github.com/lestrrat-go/iter` would panic.
    This should be fixed in `github.com/lestrrat-go/iter@v1.0.1` and
    the dependency has been updated accordingly

[Miscellaneous]
  * Added How-to style docs under `docs/`
  * github.com/goccy/go-json dependency has been updated to v0.4.8

v1.1.5 12 Mar 2021
  This is a security fix release. The JWT validation could be skipped
  for empty values. Upgrade recommended

[Security Fix]
  * JWT validation could be skipped for empty fields (#352).

[Bug fixes]
  * Allow setting JWT "typ" fields to any value (#351).
  * Remove stray replace directive in cmd/jwx/go.mod (#349)

v1.1.4 02 Mar 2021
[New features]
  * jwt.ParseRequest, jwt.ParseHeader, jwt.ParseForm have been added.
    They are convenience functions to parse JWTs out of a HTTP request.

[Miscellaneous]
  * Fix jwt.Equals() so that comparison between values containing time.Time
    actually work

  * ES256K has been made non-default. You must enable it using a build tag

     go build -tags jwx_es256k ...

    Your program will still compile without this tag, but it will return
    an error during runtime, when ES256K is encountered.
    This feature is still experimental.

v1.1.3 22 Feb 2021
[New features]
  * Implemented ES256K signing (#337)
    This feature should be considered experimental

[Miscellaneous]
  * Bump minimum required version to go1.15
  * Fix examples, bench, and cmd/jwx accidentally requiring go1.16
  * Dependencies for "github.com/goccy/go-json" has been upgraded to
    v0.4.7

v1.1.2 16 Feb 2021
[New features]
  * `RegisterCustomField()` has been added, which allows users to
    specify a private claim/field/header to decode into a particular
    object of choice, instead of map[string]interface{} or []interface{} (#332, #333)

[Bug fixes]
  * Failures for `jwk.Key.MarshalJSON()` were not properly reported (#330, #331)

[Miscellaneous]
  * `jwe.Encrypt()` now takes options. This should not matter unless you
    were somehow depending on its method signature.
  * Dependencies for "github.com/goccy/go-json" has been upgraded to
    v0.4.2

v1.1.1 05 Feb 2021
[New features]
  * Command line tool `jwx` has ben completely reworked, and it is
    now actually useful.

  * JWKs can now be serialized into PEM files with ASN.1 DER format
    data, which is useful when you need to work between JSON and PEM
    data formats.

  * Constants in jwa package now have can be listed via functions
    in each category.

  * jwe.Encrypt and jwe.Decrypt can now handle jwk.Key objects

v1.1.0 31 Jan 2021
  v1.1.0 is a release that attempts to fix as many of the quirky APIs
  that survived the API breaking change of v0.9.x -> v1.0.0. This is
  hopefully the last releases that change backwards compatibility
  in a major way, at least for some time to come.

  It is unfortunate that we need to introduce API changes, but we
  keep learning how the library is being used and the pain points
  of using this library. Most of the times these pain points are
  things that we initially did not think about, which in turn
  requires us to rethink of the API.

  If you do not wish to spend the time fixing your usage, make sure
  you have your go.mod set up to not automatically track the latest
  changes.

  However, if you do decide to use the latest version, we believe
  the API is more uniform across packages, and generally is easier
  to understand. We hope this library helps some of you out there.

[BREAKING CHANGES]
  * `jwk.Parse(io.Reader)`, `jws.Parse(io.Reader)`, `jwt.Parse(io.Reader)`,
    have all been changed to `Parse([]byte)`. To use an `io.Reader`,
    use `ParseReader(io.Reader)`. `jwe.Parse` already took `[]byte`, so
    has not been changed.

    With this change, all four package `jwe`, `jwk`, `jws`, and `jwt` follow
    the same API design, which should make things easier to navigate:

      Parse([]byte)
      ParseString(string)
      ParseReader(io.Reader)

  * `jwk.Set` is now an interface, not a struct. `jwk.Set` now has a
    well-defined API to access and modify the `jwk.Key` objects that it holds.

      Add(jwk.Key) bool
      Clear()
      Get(int) (jwk.Key, bool)
      Index(jwk.Key) int
      Len() int
      LookupKeyID() (jwk.Key, bool) // Read the section about it below
      Remove(jwk.Key) bool
      Iterate(context.Context) KeyIterator

  * `(jwk.Set).LookupKeyID()` no longer returns an array of `jwk.Key`.
    Instead, only the first key matching the given key ID will be returned.
    If you need to work with multiple keys, use `(jwk.Set).Iterate()` or
    `(jwk.Set).Get()` to look for matching keys.

  * `jwk.PublicKeyOf()` has been renamed to `jwk.PublicRawKeyOf()`,
    which converts raw keys (e.g. `rsa.PrivateKey`) to their public
    counter part (e.g. `rsa.PublicKey`)

    `jwk.PublicKeyOf()` is now used to get the public counter part of
    `jwk.Key` objects (e.g. `jwk.RSAPrivateKey` to `jwk.RSAPublicKey`)

    `jwk.PublicSetOf()` has been added to get a new `jwk.Set` but with
    all keys transformed to public keys via `jwk.PublicKeyOf()`

  * `jwk.FetchXXXX` functions have been removed. `jwk.Fetch()` remains, but
    it now takes `context.Context`, and doesn't support retrieving files
    from the local file system. See `ReadFile()` for that.

  * `jws.VerifyWithJKU()`, `jws.VerifyWithJWK()`, `jwk.VerifyWithJWKSet()`
    have all been removed, but `jwk.VerifySet(jwk.Set)` has been added.

  * `jws.SplitCompact(io.Reader)` has been changd to `jws.SplitCompact([]byte)`
    Similar to `Parse()`, `SplitCompactReader(io.Reader)` and `SplitCompactString(string)`
    have been added

  * `jws.SignLiteral` has been removed.

  * `jws.PayloadSigner` has been removed (but should not matter, because
    this as internal-use only anyways)

  * `jwe.WithPrettyJSONFormat` has been renamed to `jwe.WithPrettyFormat`

  * `jwt.Verify` has been removed. Use `jwt.Parse()` aloing with the `jwt.WithVerify()`
    option to perform signature verification. Validation of verified data
    can be performed via `(jwt.Token).Validate()` method, which has been available
    since v1.0.6

  * Package `buffer` has been removed. This package should have been an internal
    package to start with, but it was left because it had been incorporated
    in the public API in our initial versions.

  * `(jwk.Key).Get(jwk.X509CertChainKey)` no longer returns a `jwk.CertificateChain`.
    Instead it returns a raw []*x509.Certificate.

  * `(jwt.Token).Size() has been removed.

  * `jwt.WithOpenIDClaims()` has been removed. Use `jwt.WithToken(openid.New())` instead.

[New Features]
  * `jwe.ReadFile(string)`, `jwk.ReadFile(string)`, `jws.ReadFile(string)`, and
    `jwt.ReadFile(string)` have been added. In the future, we plan to introduce
    a `WithFS` option so you can read from an arbitrary file system, but this cannot
    be added while we keep go < 1.16 compatibility. If you want something like that,
    you will need to put an adapter over the jwx for the time being.

  * `(jwk.Key).PublicKey()` has been added. This method creates a corresponding
    public key, with all fields (except those that shouldn't be) copied over.
    This allows you to easily create a public key of a private key with the
    same "kid" attribute.

  * Both `jws.Verify` and `jws.Sign` methods can now handle `jwk.Key` objects, on
    top of raw keys (e.g. rsa.PrivateKey). You no longer need to conver the
    `jwk.Key` objects that you have in to raw keys before using these functions.

  * `(jws.Header).Remove(string)`, `(jwk.Key).Remove(string)`, and
    `(jwt.Token).Remove(string)` have been added. `jwe.Header` already had a `Remove()`
    method, so it has not been changed.

  * `(jwk.Key).Clone() has been added.

[Miscellaneous]
  * Default branch for the repository is now `main`.

  * Options have been reworked. In most instances, option types should now reflect
    better the contexts in which they can be used. For example, `jwk` now has
    `AutoRefreshOption` and `FetchOption` instead of a single `Option`.

  * JSON marshaling should be 10~30% faster by default (though they may take
    more allocations to achieve this).

    However, if performance is really bogging you down, you can try to enable
    the optional module github.com/goccy/go-json by enabling the "jwx_goccy" tag

      go build -tags jwx_goccy ...

    In some cases you get an extra 40~50% performance improvement in serailization
    https://github.com/lestrrat-go/jwx/pull/314#issue-560594020
    https://github.com/lestrrat-go/jwx/pull/314#issuecomment-766343888

  * Location for examples and benchmarks have changed: Now examples/ and bench/
    are their respective locations, and they are each a standalone module,
    so that in case we need extra imports (such as the case in examples)
    they do not interfere with users who just want to include jwx in their projects.

v1.0.8 15 Jan 2021
[New features]
  * Fixed `jws.Message` and `jws.Signature` to be properly formatted when
    marshaled into JSON. In the same manner, `json.Unmarshal` should also
    work as expected.
  * Added API to programatically manipulate `jws.Message` and `jws.Signature`
[Miscellaneous]
  * The order of keys are now consistent as when used with `json.Marshal`.
    Previously some objects used their own ordering, but now the code goes
    through one extra roundtrip of `json.Unmarshal`/`json.Marshal` to preserve
    compatible behavior. This *may* lead to slightly slower performance if
    you are performing `json.Marshal` over and over in very quick succession.
    Please file an issue if you have real world cases where the change
    causes problems for you.
  * Added more examples in various places.
  * Tests runs have been sped up for the most oft used cases

v1.0.7 11 Jan 2021
[New features]
  * Added jwk.AutoRefresh, which is a tool to periodically refresh JWKS. (#265)
  * Added experimental ed25519 support (#252)
[Bug fixes]
  * Fix `Set()` method for jwk Keys to properly accept either `jwk.KeyUsageType`
    or a simple string.
[Miscellaneous]
  * Updated dependencies
  * Changed options to use github.com/lestrrat-go/option
  * Various typos, unused annotations, etc, have been fixed by contributors
  * Nobody except for the author really should care, but the underlying
    `pdebug` utility, which is used for print debugging, has been
    upgraded to v3, which should stop parallel test execution from throwing
    an error when run with -race

v1.0.6 17 Dec 2020
  * Fix ECDHES ciphers where padding in AAD et al was creating
    incomptabile values with jose tool
  * Also fix ECDH-ES cek handling (#248)
  * Implement direct key encoding (#213, #249)
  * Allow JWT tokens to use default JWK if only one key is given
    and the JWT does not necessarily specifies a key (#214)
  * Deprecate jwt.Verify and introduce jwt.Validate. JWS verification
    used the term Verify, which was confusing when users wanted to
    validate the JWT token itself. (#220)
  * JWT library optins have been explicitly typed as ValidationOption
    and ParseOption (#220, #223)
  * Add jwx.DecoderSettings and jwx.WithUseNumber option to globally
    change how jwx parses JSON objects (#222)
  * Encode x5c field as base64 with padding (#244)
  * Add more interoperability tests against jose tool.
  * Special thanks to anatol and imirkin!

v1.0.5 - 28 Sep 2020
  * Reinstate PrivateParams() method in jws and jwe packages.
    These used to be available until v1.0.0, but somehow got lost during the
    big change.
    As a workaround for users of versions 1.0.0 to 1.0.4, you could have
    achieved the same thing using AsMap() methods, albeit with a slight
    performance penality (#205, #206)

v1.0.4 - 15 Aug 2020
  * Fix jwt.WithOpenIDClaims(). Looks like something got lost along
    the way, and it never really worked. (#201 #202)

v1.0.3 - 08 Jul 2020
  * `jws.Sign`, and therefore `jwt.Sign` now accept `jwk.Key` as the
    key to use for signature. (#199)
  * `jwt.Sign` could sometimes return a nil error when setting bad
    values to the protected header failed (#195)
  * More golangci-lint cleanup (#193)

v1.0.2 - 07 May 2020
  * Since 1.0.0, we took some time to play the test coverage game.
    The coverage is around 30% better, and we _did_ uncover some
    inconsistencies in the API, which got promptly fixed.
    But I'm tired of the coverage game for the time being. PR's welcome!
  * Add jwk.AssignKeyID to automatically assign a `kid` field to a JWK
  * Fix jwe.Encrypt / jwe.Decrypt to properly look at the `zip` field
  * Change jwe.Message accessors to return []byte, not buffer.Buffer

v1.0.1 - 04 May 2020
  * Normalize all JWK serialization to use padding-less base64 encoding (#185)
  * Fix edge case unmarshaling openid.AddressClaim within a openid.Token
  * Fix edge case unmarshaling jwe.Message
  * Export JWK key-specific constants, such as jwk.RSANKey, jwk.SymmetricOctetsKey, etc
  * Remove some unused code

v1.0.0 - 03 May 2020
  * All packages (`jws`, `jwe`, `jwk`, `jwt`) have all been reworked from
    the ground-up.
    * These packages now hide the actual implementation of the main structs behind an interface.
    * Header/Token structs must now be instantiated using proper constructors
      (most notably, json.Unmarshal will miserably fail if you just pass
       and empty interface via `xxx.Token` or similar)
    * Token/Header interfaces are now more or less standardized.
      The following API should be consistent between all relevant packages:
      * New()
      * Get()
      * Set()
      * Remove()
      * Iterate()
      * Walk()
      * AsMap()
    * Oft-used fields are no longer directly accessible:
      e.g. `token.KeyID = v` is no longer valid. You must set using `Set`
      (and `Remove`, if you are removing it), and use either `Get` or
      one of the utility methods such as `token.KeyID()`
    * Many helper functions and structs have been unexported. They were never
      meant to be anything useful for end-users, and hopefully it does not
      cause any problems.
    * Most errors type/instances have been removed from the public API
  * `jwt` package can now work with different token types, such as OpenID tokens.
    * `token.Sign` and `token.Verify` have been changed from methods to
      package functions `jwt.Sign` and `jwt.Verify`, to allow different
      types of tokens to be passed to the same logic.
    * Added a custom token type in `openid` sub-package to make it easier to
      work with OpenID claims
    * `jwt.Parse` (and its siblings) now accept `jwt.WithOpenIDClaims()`
  * `jwe` API has been reworked:
    * `MultiEncrypt` has been removed.
    * Serializer structs have been removed. Now you just need to call
      `jwe.Compact` or `jwe.JSON`
  * `jwk` API has been reworked:
    * `jwk.ParseKey` has been added
    * `jwk.Materialize` has been renamed to `Raw()`. A new corresponding
      method to initialize the key from a raw key (RSA/ECDSA/byte keys)
      called `FromRaw()` has also been added, which makes a nice pair.
  * `jws` API has been reworked
  * CI has been changed from Travis CI to Github Actions, and tests now
    include linting via `golangci-lint`

v0.9.2 - 15 Apr 2020
  * Maintenance release to protect users from upcoming breaking changes

v0.9.1 - 27 Feb 2020
  * Fix error wrapping in certain cases
  * Add Claims(), Walk(), and AsMap() to iterate claims, as well as
    getting the entire data out as a single map
  * Work with alternate base64 encodings when decoding

v0.9.0 - 22 May 2019
  * Start tagging versions for good measure.
