Changelog

Unreleased

Added

• Introduced subpackages and root wrappers:
  • asymm, symm, hashx, encodingx, paddingx, filex, legacy, macx.
• Added Chinese README.md and Apache-2.0 LICENSE.
• Added SM9 support in asymmetric APIs.
• Added ChaCha20 and ChaCha20-Poly1305 APIs (memory + stream wrappers where applicable).
• Added unified symmetric cipher options API:
  • CipherOptions{Mode, Padding, IV, Nonce, AAD}.
• Added AEAD APIs and wrappers:
  • AES-GCM, SM4-GCM (bytes + stream helper APIs).
• Added more symmetric mode coverage for SM4:
  • ECB/CBC/CFB/OFB/CTR (bytes + stream derived APIs).
• Added comprehensive tests across packages and root wrappers.
• Added fuzz tests for paddingx, encodingx, and symm round-trip invariants.

Changed

• Refactored monolithic implementation to subpackage architecture while preserving root-package convenience APIs.
• AES mode APIs now support generic mode selection and derived mode helpers.
• Stream APIs expanded across AES/SM4/DES/3DES and ChaCha20.
• Updated docs to include a security-first recommendation and algorithm capability matrix.
• Updated dependencies and modules for current code paths (gmsm, x/crypto).

Fixed

• Fixed Base128 encode/decode round-trip bug in encodingx.
• Corrected CRC32A test expectations and clarified CRC32A variant comments.
• Corrected default padding behavior for AES-CBC to PKCS7.

Notes

• Legacy/insecure algorithms and modes remain available for compatibility.
• Production recommendations now explicitly prefer AEAD schemes.
