我真的真的..真的需要帮助.........

-更新-

我需要帮助，因为与iOS 3DES函数相比，我的java函数给我带来了不同的结果。我从ios和java都发布了代码；当指定的明文为“
tutor.1”且MD5密钥为“ spO13 + QLZCRAe93pIXMXLg ==“（显然，MD5两者相同）时，将返回结果。

JAVA 3DES （简短）

public static String encrypt(String plaintext, String enctoken){

    if(enctoken == null)
        enctoken = "sfdjf48mdfdf3054";

    String encrypted = null;

    byte[] plaintextByte = EncodingUtils.getBytes(plaintext,"UTF-8");

    byte[] hash = Connessione.md5(enctoken);

    Log.i("ENCRYPT", "MD5: "+Base64.encodeToString(hash, 0));

    try {
        Cipher cipher = Cipher.getInstance("DESEDE/ECB/PKCS5Padding");
        SecretKeySpec myKey = new SecretKeySpec(hash,"DESede");

        cipher.init(Cipher.ENCRYPT_MODE, myKey);

        try {
            byte[] encryptedPlainText = cipher.doFinal(plaintextByte);

            encrypted = Base64.encodeToString(encryptedPlainText, 0);

            Log.i("ENCRYPT", "Pwd encrypted: "+encrypted);

            return encrypted;

        } catch (IllegalBlockSizeException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (BadPaddingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    } catch (NoSuchAlgorithmException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (NoSuchPaddingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InvalidKeyException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return "";
}

结果： R4mXAaHcFxM =

iOS 3DES-再次更新

// key value in parameters is MD5 value! It is the same for both version

// Begin to calculate bytesNeeded....
size_t bytesNeeded = 0;

ccStatus = CCCrypt(kCCEncrypt,
                   kCCAlgorithm3DES,
                   kCCOptionECBMode | kCCOptionPKCS7Padding,

                   0,
                   &bytesNeeded);

if(kCCBufferTooSmall != ccStatus){

    NSLog(@"Here it must return BUFFER TOO SMALL !!");
    return nil;
}

// .....End
// Now i do the real Crypting

char* cypherBytes = malloc(bytesNeeded);
size_t bufferLength = bytesNeeded;

if(NULL == cypherBytes)
    NSLog(@"cypherBytes NULL");

ccStatus = CCCrypt(kCCEncrypt,
                   kCCAlgorithm3DES,

                   [mData bytes],
                   [mData length],
                   nil,
                   [data bytes],
                   [data length],
                   cypherBytes,
                   bufferLength,
                   &bytesNeeded);

if(kCCSuccess != ccStatus){
    NSLog(@"kCCSuccess NO!");
    return nil;
}

return [Base64 encode:[NSData dataWithBytes:cypherBytes length:bufferLength]];

}

结果： YBAva5J2khY =

我需要iOS版本返回与Java版本相同的结果。

我在这里找到了Base64类：http : //www.imthi.com/blog/programming/iphone-sdk-
base64-encode-decode.php

我做错了什么？

感谢您的帮助和时间
