回复了 dennisge 创建的主题 › Node.js › Java 的 sha1 加盐加密和 node 实现的加密值不一样。

1. 这是原 java 的加密
a123456 => 79893503e8074330321974fa14dc44f8aa1b3df0
plainPassword = StringUtils.trim(plainPassword);
byte[] salt = Digests.generateSalt(SALT_SIZE); // af350c3413179ab4
byte[] hashPassword = Digests.sha1(plainPassword.getBytes(), salt, HASH_INTERATIONS);

private static byte[] digest(byte[] input, String algorithm, byte[] salt, int iterations) {
try {
MessageDigest digest = MessageDigest.getInstance(algorithm);

if (salt != null) {
digest.update(salt);
}

byte[] result = digest.digest(input);

for (int i = 1; i < iterations; i++) {
digest.reset();
result = digest.digest(result);
}
return result;
} catch (GeneralSecurityException e) {
throw Exceptions.unchecked(e);
}
}
