|
## 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.
