加密密钥是java和iOS的区别

我使用以下代码使用AES/ECB/PKCS5P添加算法进行加密，函数：

public static void setKey(String myKey) {
        MessageDigest sha = null;
        try {
            key = myKey.getBytes("UTF-8");
            sha = MessageDigest.getInstance("SHA-1");
            key = sha.digest(key);
            key = Arrays.copyOf(key, 16);
            secretKey = new SecretKeySpec(key, "AES");
        } catch (NoSuchAlgorithmException e) {
//            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
//            e.printStackTrace();
        }
    }
    public static String encrypt(String strToEncrypt, String secret) {
        try {
            setKey(secret);
                Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            cipher.init(Cipher.ENCRYPT_MODE, secretKey);
            return Base64.encodeToString(cipher.doFinal(strToEncrypt.getBytes("UTF-8")), Base64.DEFAULT);
        } catch (Exception e) {
//            System.out.println("Error while encrypting: " + e.toString());
        }
        return null;
    }

func AESEncryption(key: String) -> String? {
        let keyData: NSData! = (key as NSString).data(using: String.Encoding.utf8.rawValue) as NSData!
        let data: NSData! = (self as NSString).data(using: String.Encoding.utf8.rawValue) as NSData!
        let cryptData    = NSMutableData(length: Int(data.length) + kCCBlockSizeAES128)!
        let keyLength              = size_t(kCCKeySizeAES128)
        let operation: CCOperation = UInt32(kCCEncrypt)
        let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
        let options:   CCOptions   = UInt32(kCCOptionECBMode + kCCOptionPKCS5Padding)
        var numBytesEncrypted :size_t = 0
        let cryptStatus = CCCrypt(operation,
                                  algoritm,
                                  options,
                                  keyData.bytes, keyLength,
                                  nil,
                                  data.bytes, data.length,
                                  cryptData.mutableBytes, cryptData.length,
                                  &numBytesEncrypted)
        if UInt32(cryptStatus) == UInt32(kCCSuccess) {
            cryptData.length = Int(numBytesEncrypted)
            var bytes = [UInt8](repeating: 0, count: cryptData.length)
            cryptData.getBytes(&bytes, length: cryptData.length)
            var hexString = ""
            for byte in bytes {
                hexString += String(format:"%02x", UInt8(byte))
            }
            return hexString}
      return nil //Check condition nil
    }

输出：

Passcode: 769762

Encrypted values:

我在iOS中使用了以下AES加密代码，但获得了不同的加密密钥，函数：

public static void setKey(String myKey) {
        MessageDigest sha = null;
        try {
            key = myKey.getBytes("UTF-8");
            sha = MessageDigest.getInstance("SHA-1");
            key = sha.digest(key);
            key = Arrays.copyOf(key, 16);
            secretKey = new SecretKeySpec(key, "AES");
        } catch (NoSuchAlgorithmException e) {
//            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
//            e.printStackTrace();
        }
    }
    public static String encrypt(String strToEncrypt, String secret) {
        try {
            setKey(secret);
                Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            cipher.init(Cipher.ENCRYPT_MODE, secretKey);
            return Base64.encodeToString(cipher.doFinal(strToEncrypt.getBytes("UTF-8")), Base64.DEFAULT);
        } catch (Exception e) {
//            System.out.println("Error while encrypting: " + e.toString());
        }
        return null;
    }

func AESEncryption(key: String) -> String? {
        let keyData: NSData! = (key as NSString).data(using: String.Encoding.utf8.rawValue) as NSData!
        let data: NSData! = (self as NSString).data(using: String.Encoding.utf8.rawValue) as NSData!
        let cryptData    = NSMutableData(length: Int(data.length) + kCCBlockSizeAES128)!
        let keyLength              = size_t(kCCKeySizeAES128)
        let operation: CCOperation = UInt32(kCCEncrypt)
        let algoritm:  CCAlgorithm = UInt32(kCCAlgorithmAES128)
        let options:   CCOptions   = UInt32(kCCOptionECBMode + kCCOptionPKCS5Padding)
        var numBytesEncrypted :size_t = 0
        let cryptStatus = CCCrypt(operation,
                                  algoritm,
                                  options,
                                  keyData.bytes, keyLength,
                                  nil,
                                  data.bytes, data.length,
                                  cryptData.mutableBytes, cryptData.length,
                                  &numBytesEncrypted)
        if UInt32(cryptStatus) == UInt32(kCCSuccess) {
            cryptData.length = Int(numBytesEncrypted)
            var bytes = [UInt8](repeating: 0, count: cryptData.length)
            cryptData.getBytes(&bytes, length: cryptData.length)
            var hexString = ""
            for byte in bytes {
                hexString += String(format:"%02x", UInt8(byte))
            }
            return hexString}
      return nil //Check condition nil
    }

在android代码中，生成的密钥不同于iOS。您能帮助从AES/ECB/PKS5P添加算法中获取相同的加密密钥吗？我正在使用link进行检查。

在您的Swift代码中，您只是按原样使用字符串字节，而没有进行哈希运算

请注意，您不应该为此使用SHA-1；您应该改用一个，或者（最理想的）一个预打包的库来为您执行所有这些容易出错的操作。

我在iOS中获得与android相同的密钥，但没有获得与android相同的加密密钥。请编辑您的帖子，并为两个系统（android/iOS）添加示例数据，以便我们可以比较输出，谢谢。以上代码文本为：20201228165764的Android机密：Tata@123#Secretkey:1EVNN6xH8I/qd8rMmClhSQ==加密密钥：cFbx46JOjlK8Q0TpmkOrKg==SHA1密钥的Ios代码：+（NSData*）SHA1 HASHFROMSTRING:（NSString*）stringToHash{NSData*stringData=[stringToHash数据使用编码：NSASCISTRINGENCODE]；uint8[CC_SHA1_DIGEST_LENGTH]={16}；CC_SHA1（[stringData bytes]，[stringData LENGTH]，DIGEST）；NSData*hashedData=[NSData dataWithBytes:DIGEST LENGTH:16]；return hashedData；}获得与android相同的密钥，但加密密钥不同：
