• Stackoverflow - Can someone explain very simplified how the Winternitz OTS/Lamport OTS works?

How To Generate Keys

use leslie_lamport::{LamportKeyPair,LamportSignature,Algorithms};

fn main(){
    // Generate Keypair using Operating System SHA256
    let keypair = LamportKeyPair::generate(Algorithms::OS_SHA256);
    
    // Generate Keypair using Operating System SHA512
    let keypair_sha512 = LamportKeyPair::generate(Algorithms::OS_SHA512);
    
    // Generate Keypair using Rust Library For Blake2b
    let keypair_blake2b = LamportKeyPair::generate(Algorithms::BLAKE2B);
}

How To Sign

use leslie_lamport::{LamportKeyPair,LamportSignature,Algorithms};

fn main(){
    // Generate Keypair
    let keypair = LamportKeyPair::generate(Algorithms::OS_SHA256);
    
    // Generate Signature For 512 bit input
    let sig = keypair.sign("b7dba1bc67c531bffb14fbd7f6948540dba10981765a0538575bed2b6bf553d43f35c287635ef7c4cb2c379f71218edaf70d5d73844910684103b99916e428c2");

    // Check If It Is Verified
    let is_verified: bool = sig.verify();

    // Print Verification
    println!("Is Verified: {}",is_verified)
}
