Examples with Crypto tech.pegasys.signers.bls.keystore.model.Crypto used on opensource projects

Example 1 with Crypto

use of tech.pegasys.signers.bls.keystore.model.Crypto in project signers by ConsenSys.

the class KeyStore method encryptUsingCipherFunction.

private static Crypto encryptUsingCipherFunction(final Bytes secret, final String password, final KdfParam kdfParam, final Cipher cipher) {
    final Bytes decryptionKey = kdfParam.generateDecryptionKey(password);
    final Bytes cipherMessage = applyCipherFunction(decryptionKey, cipher, true, secret.toArrayUnsafe());
    final Bytes checksumMessage = calculateSHA256Checksum(decryptionKey, cipherMessage);
    final Checksum checksum = new Checksum(checksumMessage);
    final Cipher encryptedCipher = new Cipher(cipher.getCipherFunction(), cipher.getCipherParam(), cipherMessage);
    final Kdf kdf = new Kdf(kdfParam);
    return new Crypto(kdf, checksum, encryptedCipher);
}

Example 2 with Crypto

use of tech.pegasys.signers.bls.keystore.model.Crypto in project signers by ConsenSys.

the class KeyStore method encrypt.

/**
 * Encrypt the given BLS12-381 key with specified password.
 *
 * @param blsPrivateKey BLS12-381 private key in Bytes to encrypt. It is not validated to be a
 *     valid BLS12-381 key.
 * @param blsPublicKey BLS12-381 public key in Bytes. It is not validated and stored as it is.
 * @param password The password to use for encryption
 * @param path Path as defined in EIP-2334. Can be empty String.
 * @param kdfParam crypto function such as scrypt or PBKDF2 and related parameters such as dklen,
 *     salt etc.
 * @param cipher cipher function and iv parameter to use.
 * @return The constructed KeyStore with encrypted BLS Private Key as cipher.message and other
 *     details as defined by the EIP-2335 standard.
