lamport_signature is a Rust implementation of the Lamport one-time signature scheme.
Difference from the lamport_sigs crate
- lamport_signature can use arbitrary fixed output size digest algorithm implemented in RustCrypto/hashes.
- lamport_signature can use arbitrary RNG (Random Number Generator) implemented in rust-lang-nursery/rand.
