v2.0.18

Compare Source

v2.0.18 03 Dec 2023
[Security Fixes]
  * [jwe] A large number in p2c parameter for PBKDF2 based encryptions could cause a DoS attack,
    similar to https://nvd.nist.gov/vuln/detail/CVE-2022-36083.  All users who use JWE via this
    package should upgrade. While the JOSE spec allows for encryption using JWE on JWTs, users of
    the `jwt` package are not immediately susceptible unless they explicitly try to decrypt
    JWTs -- by default the `jwt` package verifies signatures, but does not decrypt messages.
    [GHSA-7f9x-gw85-8grf]

v2.0.17

v2.0.17 20 Nov 2023
[Bug Fixes]
  * [jws] Previously, `jws.UnregisterSigner` did not remove the previous signer instance when
    the signer was registered and unregistered multiple times (#​1016). This has been fixed.

[New Features]
  * [jwe] (EXPERIMENTAL) `jwe.WithCEK` has been added to extract the content encryption key (CEK) from the Decrypt operation.
  * [jwe] (EXPERIMENTAL) `jwe.EncryptStatic` has been added to encrypt content using a static CEK.
    Using static CEKs has serious security implications, and you should not use
    this unless you completely understand the risks involved.

v2.0.16

v2.0.16 31 Oct 2023
[Security]
  * [jws] ECDSA signature verification requires us to check if the signature
    is of the desired length of bytes, but this check that used to exist before
    had been removed in #​65, resulting in certain malformed signatures to pass
    verification.

    One of the ways this could happen if R is a 31 byte integer and S is 32 byte integer,
    both containing the correct signature values, but R is not zero-padded.

       Correct = R: [ 0 , ... ] (32 bytes) S: [ ... ] (32 bytes)
       Wrong   = R: [ ... ] (31 bytes)     S: [ ... ] (32 bytes)

    In order for this check to pass, you would still need to have all 63 bytes
    populated with the correct signature. The only modification a bad actor
    may be able to do is to add one more byte at the end, in which case the
    first 32 bytes (including what would have been S's first byte) is used for R,
    and S would contain the rest. But this will only result in the verification to
    fail. Therefore this in itself should not pose any security risk, albeit
    allowing some illegally formated messages to be verified.

  * [jwk] `jwk.Key` objects now have a `Validate()` method to validate the data
    stored in the keys. However, this still does not necessarily mean that the key's
        are valid for use in cryptographic operations. If `Validate()` is successful,
    it only means that the keys are in the right _format_, including the presence
    of required fields and that certain fields have proper length, etc.

[New Features]
  * [jws] Added `jws.WithValidateKey()` to force calling `key.Validate()` before
    signing or verification.

  * [jws] `jws.Sign()` now returns a special type of error that can hold the
    individual errors from the signers. The stringification is still the same
    as before to preserve backwards compatibility.

  * [jwk] Added `jwk.IsKeyValidationError` that checks if an error is an error
    from `key.Validate()`.

[Bug Fixes]
  * [jwt] `jwt.ParseInsecure()` was running verification if you provided a key
    via `jwt.WithKey()` or `jwt.WithKeySet()` (#​1007)

v2.0.15

v2.0.15 19 20 Oct 2023
[Bug fixes]
  * [jws] jws.Sign() now properly check for valid algorithm / key type pair when
    the key implements crypto.Signer. This was caused by the fact that when 
    jws.WithKey() accepted keys that implemented crypto.Signer, there really
    is no way to robustly check what algorithm the crypto.Signer implements.

    The code has now been modified to check for KNOWN key types, i.e. those
    that are defined in Go standard library, and those that are defined in
    this library. For example, now calling jws.Sign() with jws.WithKey(jwa.RS256, ecdsaKey)
    where ecdsaKey is either an instance of *ecdsa.PrivateKey or jwk.ECDSAPrivateKey
    will produce an error.

    However, if you use a separate library that wraps some KMS library which implements
    crypto.Signer, this same check will not be performed due to the fact that
    it is an unknown library to us. And there's no way to query a crypto.Signer
    for its algorithm family.

v2.0.14

Compare Source

v2.0.14 17 Oct 2023
  [New Features]
  * [jwk] jwk.IsPrivateKey(), as well as jwk.AsymmetricKey has been added.
    The function can be used to tell if a jwk.Key is a private key of an
    asymmetric key pair.
  [Security]
  * golang.org/x/crypto has been updated to 0.14.0. The update contains a fix for HTTP/2
    rapid reset DoS vulnerability, which some security scanning softwares may flag.
    However, do note that this library is NOT affected by the issue, as it does not have
    the capability to serve as an HTTP/2 server. This is included in this release
    document so that users will be able to tell why this library may be flagged
    when/if their scanning software do so.

v2.0.13

Compare Source

v2.0.13 26 Sep 2023
[New Features]
  * [jwk] jwk.Equal has been added. Please note that this is equivalent to
  comparing the keys' thumbprints, therefore it does NOT take in consideration
  non-essential fields.

[Miscellaneous]
  * Various documentation fixes and additions.
