Cristian Cezar Moisés	4874010d0e	v4.1.0: source-only build, multithreaded-encryption fix, security hardening ... Build from source with no vendored binaries: - Remove prebuilt libzuptsdk.so / libpqvaptvupt.so (and a stray .pyc). The default build needs only a C compiler + make; it links no external library and installs no .so. The libzuptsdk-backed modes (Argon2id KDF, --pq-sdk, --pq-box) are gated behind an opt-in `make WITH_SDK=1`. The default password KDF is PBKDF2-SHA256 and --pq (native ML-KEM-768 + X25519) is the built-in PQ mode. openSUSE/RPM/deb/AUR/Homebrew/Nix recipes bumped to 4.1.0; the openSUSE spec now builds source-only (%files ships no .so, %build/%install WITH_SDK=0). Fix: multithreaded encrypted archives were unextractable on the native AEAD path. The parallel compress/decompress workers skipped the F-09 frame-preface AAD that the serial path and the archive's AAD_PREFACE flag bind into every block MAC, so each multithreaded block failed authentication. The workers now bind the preface via a shared serializer; output is byte-identical across thread counts and interoperates with single-threaded archives (also fixes `--kdf pbkdf2 -t N` in any build). Security hardening (crafted-archive memory safety + crypto): - LZH raw code-length stack overflow + huff_lut OOB write - overflow-safe bounds in parse_index and solid-mode extract (heap OOB read) - SEQ decoder safe-zone heap overflow (litlen+matchlen reserve) - require the per-block ENCRYPTED flag on encrypted archives (plaintext forgery) - cap archive-supplied PBKDF2 iteration count (KDF-amplification DoS) - non-elidable secret wipe in the SDK path; restored disk images created 0600 Docs: remove AUDIT.md / BENCHMARKS.md / ROADMAP.md; trim marketing/AI-styled text and correct KDF/PQ facts across README, SECURITY, INSTALL, DISTRIBUTION, THREAT_MODEL, THIRD-PARTY-NOTICES, the man page, and packaging READMEs. Wire format v1.6 unchanged.	2026-07-07 19:45:37 -03:00
Cristian Cezar Moisés	544a2cd647	v4.0.0: codec 2.60.4 security release, --pq-box sealed-box mode, F-16 fix ... Major release. Highlights: - Codec: vendored VaptVupt codec moves to canonical 2.60.4 security release. Fixes a high-severity OOB heap write in the AVX2 decode fast path (reachable on a valid stream sized to exactly content_size, both tail variants). Brings CBMC-formally-verified BCJ filters with automatic ELF/PE/Mach-O detection. Compressed output stays byte-identical (ratio gate Δ 0.00%); wire format unchanged at v1.6. - New --pq-box sealed-box recipient mode (vendored libpqvaptvupt 0.6.0): ML-KEM-768 + X25519 combined via HKDF-SHA256 with domain separation, AES-256-CTR + HMAC-SHA256 EtM. Legacy --pq and --pq-sdk stay readable. - F-16: discloses and fixes a pre-existing data-loss defect in the <= 3.8.0 in-tree BCJ encoder. Full back-compat matrix decodes byte-exact under 4.0.0; every readable pre-4.0 archive remains readable. Repository hygiene: - Sync full 4.0.0 source tree (codec, crypto, SDK, GUI, packaging, tests). - Remove internal scratch files (PROMPT.md, FORMAL_AUDIT_PROMPT.md) and superseded version-specific docs (INTEGRATION_PROTOCOL_2.60.4.md, docs/FINDINGS-2.x.md) and a stray test binary. - Refresh README download/install section to real 4.0.0 release assets; bump version badge to 4.0.0. - Add .gitignore for build outputs (keeps vendored prebuilt libraries).	2026-06-10 18:48:58 -03:00
