EthKey

Ethereum keys management supporting keystores in formats used by geth, parity and pyethereum.

Features

• random key pair generation
• key serialization/deserialization
• keystore password change
• signing and verification

Usage

Add this to your Cargo.toml:

[dependencies]
ethkey = "0.3"

Example

(Rust edition 2018)

use ethkey::prelude::*;

fn main() {
    let key = EthAccount::load_or_generate("/tmp/path/to/keystore", "passwd")
        .expect("should load or generate new eth key");

    println!("{:?}", key.address());

    let message = [7_u8; 32];

    // sign the message
    let signature = key.sign(&message).unwrap();

    // verify the signature
    let result = key.verify(&signature, &message).unwrap();
    println!("{}", if result {"verification ok"} else {"wrong signature"});
}

A "prelude" for users of the ethkey crate.

use ethkey::prelude::*;

The prelude may grow over time.
