Two Malicious Rust Crates Impersonate Popular Logger to Steal Wallet Keys
Socket uncovers malicious Rust crates impersonating fast_log to steal Solana and Ethereum wallet keys from source code.
@chainsafe/bls-keygen
Advanced tools
Utility functions for generating BLS secret keys, built for NodeJs and Browser.
Implementation follows EIPS: EIP-2334, EIP-2333
For low-level EIP-2333 and EIP-2334 functionality, see @chainsafe/bls-hd-key.
import {
generateRandomSecretKey,
deriveKeyFromMnemonic,
deriveKeyFromEntropy,
deriveKeyFromMaster,
deriveEth2ValidatorKeys,
} from "@chainsafe/bls-keygen";
// random secret key
const secretKey = generateRandomSecretKey();
...
// secret key from mnemonic and optional EIP-2334 path
const masterSecretKey = deriveKeyFromMnemonic(
"impact exit example acquire drastic cement usage float mesh source private bulb twenty guitar neglect",
);
const childSecretKey = deriveKeyFromMnemonic(
"impact exit example acquire drastic cement usage float mesh source private bulb twenty guitar neglect",
"m/12381/3600/0/0"
);
...
// secret key from entropy and optional EIP-2334 path
const masterSecretKey = deriveKeyFromEntropy(entropy);
const childSecretKey = deriveKeyFromEntropy(
entropy,
"m/12381/3600/0/0"
);
...
// child secret key from master secret key and EIP-2334 path
const childSecretKey = deriveKeyFromMaster(
masterSecretKey,
"m/12381/3600/0/0"
);
...
// create multiple eth2 validator keys from a master secret key
const keys0 = deriveEth2ValidatorKeys(masterSecretKey, 0);
const keys1 = deriveEth2ValidatorKeys(masterSecretKey, 1);
const { signing, withdrawal } = keys0;
