我想从十六进制私钥中获取以太坊的公共地址。我为此写了一个rust脚本-

extern crate hex;
extern crate secp256k1;
extern crate sha3;

use secp256k1::{PublicKey, SecretKey};
use sha3::Keccak256;

fn main() {
    let context = secp256k1::Secp256k1::new();
    let private_key: &[u8] =
        "616E6769652E6A6A706572657A616775696E6167612E6574682E6C696E6B0D0A".as_bytes();
    let secret_key = SecretKey::from_slice(&hex::decode(private_key).unwrap());
    let public_key = PublicKey::from_secret_key(&context, &secret_key.unwrap());
    println!("Public Key -> {:?}", public_key);
    let mut hasher = Keccak256::new();
    // making it an ethereum address
}

但是let mut hasher = Keccak256::new();给了我一个错误-

error[E0599]: no function or associated item named `new` found for struct `CoreWrapper` in the current scope

试试这个:

use sha3::{Digest, Sha3_256};

let mut hasher = Sha3_256::new();
hasher.update(message);
let result = hasher.finalize();

尝试此解决方案:

use sha3::{Digest, Keccak256};
let mut hasher = Keccak256::new();
hasher.update(data);
let result = hasher.finalize();
