Struct ripple_keypairs::PublicKey

pub struct PublicKey { /* fields omitted */ }

A public key that can be used to derive an XRP Ledger classic address and verify signatures

Examples

use ripple_keypairs::{Seed, error};

let seed = "sp5fghtJtpUorTwvof1NpDXAzNwf5".parse::<Seed>()?;

let (private_key, public_key) = seed.derive_keypair()?;

assert_eq!(public_key.derive_address(), "rU6K7V3Po4snVhBBaU29sesqs2qTQJWDw1");

assert_eq!(public_key.to_string(), "030D58EB48B4420B1F7B9DF55087E0E29FEF0E8468F9A6825B01CA2C361042D435");

let msg = "Test message";

assert_eq!(public_key.verify(&msg, &private_key.sign(&msg)), Ok(()));
assert_eq!(public_key.verify(&msg, &"bad signature"), Err(error::InvalidSignature));

Implementations

impl PublicKey

pub fn verify(
    &self,
    message: &impl AsRef<[u8]>,
    signature: &impl AsRef<[u8]>
) -> Result<()>

Verify a signature

Errors

Returns error::InvalidSignature if the signature is invalid.

pub fn derive_address(&self) -> String

Derive an XRP Ledger classic address
