Li₂utils

There is a significant lack of simple FIPS 204 (CRYSTALS-Dilithium) signature generators/verifiers. This simple toolset is written in Rust and contains three tools: li2sign, li2verify, and li2fingerprint.

This is provided for your convenience, and contains no audit, assurance, or fitness for any purpose whatsoever.

This toolset relies completely on the great fips204 Rust library by the RustCrypto Developers, and uses ML‐DSA‐44 parameters.

You can install the toolset from Crates.io by issuing: cargo install li2utils

li2sign

Usage: li2sign

Takes data from stdin and uses the private key from ./private_key.bin if present; otherwise, it generates a new private key and stores it in that file. Then, it signs the given data, and outputs the signature to stdout and the public key to stderr.

li2verify

Usage: li2verify <public_key_hex> <signature_hex>

Takes data from stdin and verifies it against public_key_hex and signature_hex. Outputs "Signature is valid." to stdin or "Signature is invalid." to stderr. On invalid signature, the program exits with 1.

li2fingerprint

Usage: li2fingerprint <public_key_hex>

Calculates SHAKE256 hash of the public_key_hex to provide 21-byte fingerprint in chunks of 3 bytes in hexadecimal (inspired by OpenPGP but with raw public key without the packet structure). By diverging from the PGP format, these fingerprints can be easily distinguished from PGP keys.

Example usage

Generate signature

Command:

echo -n "Hello world"|li2sign

Output:
