- Linux runner lacks patchelf; add the patchelf PyPI package (linux
only) to dev deps so uv run puts it on PATH for auditwheel repair.
- setup.py anchored all libaegis paths to __file__: newer setuptools
invoke the compiler from a temp build dir, breaking CWD-relative
-Ilibaegis/src/include on Windows (C1083 aegis.h not found).
Fixes CI EXE001 (shebang on non-executable file). Running the script
directly puts src/aeg on sys.path, where aeg/random.py would shadow the
stdlib random module that secrets and others import — pop it before any
imports so both direct execution and -m aeg.benchmark work.
Following upstream libaegis 0.10.5 (874f884): the absorbing-mode
unauthenticated pair is deprecated in favor of the pure keystream XOR.
- stream_xor(key, nonce, data, into=None): same function encrypts and
decrypts; output equals data XOR stream(key, nonce); supports in-place
use via into (same buffer semantics as elsewhere).
- encrypt_unauthenticated/decrypt_unauthenticated kept for the old
format but now emit DeprecationWarning; removed from README (stream_xor
documented under Keystream generation instead).
Each cipher module's random() now returns a thread-local Random that is
created on first use and reused thereafter. Each thread gets its own
OS-seeded generator (own key+nonce), so no locking and no cross-thread
nonce collisions. random_key() and random_nonce() draw from this CSPRNG
instead of secrets.token_bytes, making them as fast as the stream.
Changes made in the aegis256x4.py template and regenerated.
StreamStorage wraps any seek-based file-like object using the same
lock + seek/read/write pattern as FileStorage's fallback for platforms
without pread/pwrite. create()/open() auto-wrap io.BytesIO, so in-memory
use no longer requires the explicit BytesIOStorage wrapper. The caller
keeps ownership of the stream (Raf does not close it).
mmap-backed buffer locked against swapping (mlock/VirtualLock) and
excluded from core dumps (MADV_DONTDUMP) where available, wiped on
close. Not used for return values; intended as an 'into' target (and
key input) to keep sensitive material out of the regular heap.
Adapted from quantumpipe's securebuf module.
- requires-python >= 3.12; abi3 limited API tag cp310 -> cp312
- util.Buffer now imported directly from collections.abc (no fallback)
- release.py: ABI3 wheel covers 3.12-3.15; PyPy wheels dropped (PyPy
has no 3.12 support yet)
Running generate.py standalone previously rewrote _ciphers.py with
formatting that differed from the committed (ruff-formatted) style,
creating spurious diffs. release.py already ran ruff after generation;
now generate.py does too, so both entry points leave the tree in the
same state.
Implement Python bindings for the libaegis 0.10.6 RAF API:
- Thin per-variant wrappers (raf_create/open/read/write/truncate/size/
sync/close, merkle_rebuild/verify/commitment) generated from a template
in tools/generate.py, with errno-mapped exceptions.
- aeg.raf: high-level file-like API (Raf, create/open/probe,
derive_master_key) with pluggable Storage backends (FileStorage,
BytesIOStorage) and Merkle tree integrity via a MerkleHasher protocol
(SHA256MerkleHasher default), adapted from pyaegis (MIT).
- aeg.random: CSPRNG facility. Random produces AEGIS keystream seeded
once from the OS, exposed per cipher module as cipher.random() and
usable as the RAF RNG (as_raf_rng) or standalone RandomSource.
- Tests: roundtrip/random-access/seek/truncate/Merkle coverage for all
six variants, pyaegis-style API checks, and a Merkle fuzz test.
Matrix job builds and tests wheels on linux/macos/windows (no Gitea
release, unlike mediahive); publish job uploads the merged dist/ to PyPI
only after all platforms succeed. release.py gains --no-upload for the
matrix jobs.
- Mac class follows hashlib API: digest functions added and finalization no longer modifies state.
- Encryptor and Decryptor now raise RuntimeError if still used after final.
Documentation updated with the changes and further examples.
Tests updated with the changes, new test module for error cases (test_raises).
Docstrings improved.
