wolfCrypt-py Release 5.9.2 (Jul 16, 2026)
==========================================
* Update to wolfSSL version 5.9.2
* Update license from GPLv2 to GPLv3
* 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 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 type annotations across all public modules and ship a `py.typed` marker so downstream projects can consume them.
