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.

%description
|
|
VaptVupt (formerly Zupt; renamed in v3.0.0 due to a prior INPI Brasil
|
|
trademark on the name "Zupt") compresses and encrypts backup archives.
|
|
LZ + ANS compression (VaptVupt codec, ~2-3 GB/s decompression on x86_64
|
|
with AVX2 / aarch64 with NEON), AES-256-CTR + HMAC-SHA256 per-block
|
|
authenticated encryption, multi-threaded, with ML-KEM-768 + X25519
|
|
post-quantum hybrid key encapsulation (FIPS 203 + RFC 7748) via --pq.
|
|
|
|
This package builds entirely from source with no external library
|
|
dependency. The password KDF is PBKDF2-SHA256 (600k iterations). The
|
|
optional libzuptsdk-backed modes (Argon2id KDF, --pq-sdk, --pq-box) are
|
|
not built here; they require an upstream WITH_SDK=1 build against the
|
|
separately distributed libzuptsdk/libpqvaptvupt.
|
|
|
|
Pure C11, ~5,000 lines of core code. Constant-time cryptographic
|
|
primitives are formally verified with Jasmin on x86_64
|
|
(zupt_mac_verify_ct, zupt_ct_select_32); a clean C fallback runs on
|
|
aarch64 and other architectures.
