Bumps signxml from 2.6.0 to 4.0.4.

Release notes

Sourced from signxml's releases.

v4.0.4

This release contains security fixes for two security advisories:

  • Signature verification with HMAC is vulnerable to an algorithm confusion attack (GHSA-6vx8-pcwv-xhf4)

  • Signature verification with HMAC is vulnerable to a timing attack (GHSA-gmhf-gg8w-jw42)

v4.0.3

  • Fix issue with support for deprecated PyOpenSSL certificates

    • Fully remove the ca_path parameter; add docs for signature location pinning

v4.0.2

  • XAdES signing: remove duplicate timezone information from SigningTime (#266)

v4.0.1

  • Verifier: Accept PyOpenSSL cert input, add deprecation warning

v4.0.0

  • Replace PyOpenSSL with Cryptography (#260)

    - This is a major infrastructure change that replaces core
      certificate parsing, key processing, signature validation, and
      certificate chain validation functions previously provided by
      PyOpenSSL with those provided by Cryptography. Care was taken to
      preserve the exisitng API, including exception types, but many
      error messages raised in various error conditions have changed. If
      you see unexpected behavior and you have reason to believe it is
      incorrect, please file an issue.
    
    • Breaking change: the ca_path parameter, previously used to specify
      CA certificate stores, is no longer supported. Use the ca_pem_file
      parameter instead.
  • Raise error when invalid certificate string is passed as input to signer

  • Fix public key matching for ECDSA (#245)

v3.2.2

  • Update upper bound on lxml dependency to allow lxml 5

    • Bump minimum dependency versions to align with Ubuntu 20.04

    • Test and release infrastructure improvements

v3.2.1

  • Use dataclass.replace in SignatureReference construction. Fixes #231
