Crate ethkey

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

Features

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

Usage

[dependencies]
ethkey = "0.3"

Example

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"});
}

Modules

prelude

A "prelude" for users of the ethkey crate.

Structs

PublicKey	Represents public part of the Ethereum key.
SecretKey	Represents the private part of the Ethereum key
Signature	Message signature

Enums

Constants

KEYSTORE_VERSION
KEY_ITERATIONS	HMAC fn iteration count; a compromise between security and performance

Type Definitions

Message	32 bytes Message for signing and verification
Password	Password. It is overwritten with zeros after memory is released.
