https://qbit.org/changelog/qbit-libbitcoinpqc Releases of qbit-libbitcoinpqc. 2026-11-02T15:40:07Z Qbit https://qbit.org/ tag:qbit.org,2026:changelog/qbit-libbitcoinpqc/v0-3-2 2026-11-02T15:40:07Z 2026-11-02T15:40:07Z

The library now reports a secret key that fails validation at signing as BAD_KEY rather than BAD_SIGNATURE, and allocation failures as the new OUT_OF_MEMORY code, so callers that branch on error codes should handle both. Debug builds need up to 80 KiB more stack; keys, signatures and verification results are unchanged.

Key generation and signing now wipe SLH-DSA secret-key material from the stack before returning, which makes them about 12% and 10% slower in the release benchmarks. The API, ABI, keys, signatures and verification results are unchanged.

First public release for Qbit, supporting only the bounded SLH-DSA-SHA2-128s-bounded30 profile through the C and Rust APIs. Renames the Cargo package to qbit-libbitcoinpqc while keeping the bitcoinpqc crate name, the C headers and the bitcoin_pqc_* ABI namespace.
