Crate ripple_keypairs

Cryptographic key pairs for the XRP Ledger

An implementation of XRP Ledger keypairs & wallet generation which supports rfc6979 and eddsa deterministic signatures.

Examples

Generate a random XRP Ledger address

use ripple_keypairs::Seed;

let seed = Seed::random();
let (_, public_key) = seed.derive_keypair()?;
let address = public_key.derive_address();

assert!(address.starts_with("r"));

Encode a seed in Base58 XRP Legder format

use ripple_keypairs::{Seed, Entropy, Algorithm};

// In the real world you **must** generate random entropy
let entropy = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16];
let seed = Seed::new(Entropy::Array(entropy), &Algorithm::Secp256k1);

assert_eq!(seed.to_string(), "sp5fghtJtpUorTwvof1NpDXAzNwf5");

Parse a string into a seed

use std::str::FromStr;
use ripple_keypairs::{Seed, error};

let seed = Seed::from_str("sp5fghtJtpUorTwvof1NpDXAzNwf5")?;

assert_eq!(seed, "sp5fghtJtpUorTwvof1NpDXAzNwf5".parse()?);
assert_eq!(Err(error::DecodeError), "bad seed".parse::<Seed>());
