wolfCrypt-py Release 5.9.2 (Jul 1, 2026)

  • Update to wolfSSL version 5.9.2
  • Make t2b support other types
  • Fix ChaCha20Poly1305 to be singleshot
  • Fix padding of small ECC signatures
  • ML-DSA: Add support for generating private key deterministically from seed
  • ML-DSA: Add support for deterministic signing
  • ML-DSA: Add support for signing and verifying with context
  • ML-DSA: Signing without context is disabled by default. Note: this can be enabled by compiling the C-library with --enable-mldsa=yes,no-ctx
  • Drop support for end-of-life Python versions (<= 3.9)
  • Add extra nonce parameter to Random generator
  • Add type annotations to utils and random
  • Add pyproject.toml for modern Python packaging
  • Fix AES-SIV silently mangling associated data
  • Fix ChaCha decrypt stream state wiping on first call
  • Fix Random AttributeError on builds without ML-KEM/ML-DSA
  • Fix Ed448 ctx cdef to match wolfSSL header signature
  • Fix wc_ecc_import_unsigned cdef to match wolfSSL header
  • Fix wc_RsaPSS_Verify const qualifier in cdef
  • Fix wc_GetPkcs8TraditionalOffset non-const bytes handling
  • Validate raw element lengths in EccPublic/EccPrivate.decode_key_raw
  • Improve WolfCryptError exception to include error return value
  • Code modernization: f-strings, remove unicode prefix, remove redundant code
  • Fix issue in AES-GCM tag verification
  • Address many small issues found by Fenrir
  • Add reseed support to random number generator
  • The RsaPublic key parameter is now mandatory as it is always needed by an internal function call.
  • The native_object attribute of Random is now read-only.
  • Add typing annotations.
