Documentation

lib-q-sig

Post-quantum signature façade for lib-Q: optional integrations with ML-DSA, SLH-DSA, and FN-DSA behind feature flags. Exposes a cdylib + rlib crate for native and WASM bundles.

Algorithms (feature-gated)

Feature Backend crate Notes
ml-dsa lib-q-ml-dsa FIPS 204; ring layer in lib-q-ring.
slh-dsa lib-q-slh-dsa FIPS 205; caller-supplied RNG for no_std-friendly tests.
slh-dsa-std above + lib-q-random Implicit OS-backed RNG when APIs allow None.
slh-dsa-wasm above + WASM deps Browser/JS-oriented builds.
fn-dsa lib-q-fn-dsa FIPS 206.

Default features: alloc, ml-dsa, std.
