Struct leslie_lamport::LamportSignature

pub struct LamportSignature {
    pub hash: Algorithms,
    pub pk: Vec<String>,
    pub input: String,
    pub signature: Vec<String>,
}

Lamport Signature

After Signing with the LamportKeyPair struct, you can keep the LamportSignature struct Public. Your LamportKeyPair will now be useless for signing as it's a One-Time Signature.

This Struct Contains:

• The Hashing Algorithm as Enum Algorithms
• The Public Key as a Vector<Strings>
• The Input String as a String
• The Signature as a Vector<Strings>

Example Usage

Its Only Function is for Verification Purposes

use leslie_lamport::{LamportKeyPair,Algorithms,LamportSignature};
 
// Generate Keypair
let keypair = LamportKeyPair::generate(Algorithms::OS_SHA256);
 
// Generates a "LamportSignature" Struct for a One-Time Signature For a 512-bit Hexadecimal String
let signature = keypair.sign("A55FE31CB83313443F38356A065F9E6386BE591C30490ECC6994B0C152D46D80ABC010DF01257FFEC437402967995D5C34EAD950E0C62C3BCAFF34BCEFB3BDF7");
 
// Verify Signature
let is_verified: bool = signature.verify();
 

Fields

hash: Algorithms

pk: Vec<String>

input: String

signature: Vec<String>

Implementations

impl LamportSignature

pub fn verify(&self) -> bool

The Verify Function that returns a boolean value when verifying whether the signature matches the public key and input

It must:

• The Number of Public Keys must be divisible by 8 and then 2 to retrieve n
• THe Number of Signatures must be at most half of the Public Keys
• The Input Must Be At Most The Size Of n in Bytes And Be In Hexadecimal (which is converted to binary)
