PBKDF2带HMACSHA1 Java到Swift 3

我想使用Java中相同的算法（PBKDF2WithHmacSHA1）在swift 3中散列密码

以下是Java代码：

char[] passwordChars = password.toCharArray();
byte[] saltBytes = Constantes.SALT.getBytes();
PBEKeySpec spec = new PBEKeySpec(passwordChars, saltBytes, Constantes.ITERATIONS,192);

try {
    SecretKeyFactory  key = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
    byte[] hashedPassword = key.generateSecret(spec).getEncoded();   
    return String.format("%x", new BigInteger(hashedPassword));
} catch {[..]}

关键字“测试”的结果示例：2d21d1a136b22280a47499789ae4bedfb63ce900e97064

我试着像这样使用CryptoSwift：

let passwordArray: [UInt8] = Array(test.utf8)
let saltArray: [UInt8] = Array(salt.utf8)

let result = try! PKCS5.PBKDF2(password: passwordArray, salt: saltArray, iterations: iter, keyLength: 192, variant: .sha1).calculate()

结果:

我注意到结果不一样

你知道问题可能来自哪里吗？

是的，我有解决办法 问题出在Android上：

SecretKeyFactory key = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
        byte[] hashedPassword = key.generateSecret(spec).getEncoded();
        DebugLog.logd("Tools","hashPassword tableau bytes = " + hashedPassword);            
        return toHex(hashedPassword);

使用toHex（）：

您应该会找到与Swift相同的结果：-）

您得到答案了吗？我也有同样的问题是的，我发布了我的解决方案，很抱歉没有回答

private static String toHex(byte[] array) {
    BigInteger bi = new BigInteger(1, array);
    String hex = bi.toString(16);
    int paddingLength = (array.length * 2) - hex.length();
    if(paddingLength > 0)
        return String.format("%0" + paddingLength + "d", 0) + hex;
    else
        return hex;
}
