Implementations

impl Secp256r1PublicKey

pub fn derive_address(&self) -> Address

Available on crate feature hash only.

Derive an Address from this Public Key

An Address can be derived from a Secp256r1PublicKey by hashing the bytes of the public key prefixed with the Secp256r1 SignatureScheme flag (0x02).

hash( 0x02 || 33-byte secp256r1 public key)

use iota_sdk_types::{Address, Secp256r1PublicKey, hash::Hasher};

let public_key_bytes = [0; 33];
let mut hasher = Hasher::new();
hasher.update([0x02]); // The SignatureScheme flag for Secp256r1 is `2`
hasher.update(public_key_bytes);
let address = Address::new(hasher.finalize().into_inner());
println!("Address: {}", address);

let public_key = Secp256r1PublicKey::new(public_key_bytes);
assert_eq!(address, public_key.derive_address());
