Sign: Set smlen to 0 in case of failure by mkannwischer · Pull Request #959 · pq-code-package/mldsa-native

mkannwischer · 2026-02-10T03:18:33Z

No description provided.

In mld_sign if a failure is returned from mld_sign_signature, we currently set the smlen to mlen (mld_sign_signature returns smlen=0, and we increment it by mlen). This commit changes it so that in the case of failure smlen=0 is returned. Signed-off-by: Matthias J. Kannwischer <matthias@kannwischer.eu>

This commit adds a reference to FIPS204 that states that t0 does not need to be considered secret. That replaces an old reference to an eprint report stating the same. Signed-off-by: Matthias J. Kannwischer <matthias@kannwischer.eu>
