Module fiduciary_crypto 

Fiduciary Cryptography (ML-DSA / FIPS-204) Implementation

Post-quantum digital signatures using real ML-DSA-65 (FIPS-204, NIST security category 3) via the pure-Rust fips204 crate. Produced signatures are interoperable with any conformant FIPS-204 implementation. Pure Rust, WASM-compatible (uses getrandom for entropy).

NOTE: revisions before 0.0.12 contained a SHA3-based simulation of ML-DSA for demonstration only. That fake lattice path has been removed and replaced with the standardized algorithm. The serialized key/signature byte layouts therefore changed.
