需要C＃等价的java Triple DES加密算法 [英] Need C# equivalent of java Triple DES Encryption Algorithm

问题描述

我得到了针对引脚加密方法的以下示例java编码。但我需要在c＃应用程序上执行此操作。我尝试了从互联网上找到的一些示例方法，但仍未找到合适的解决方案。有人可以帮我在c＃上做这件事。

Hi,

I got the below sample java coding for the pin encryption method. But I need to do this on c# application. I tried some example methods found out from the internet but still not found a proper solution. can some one help me to do this on c#.

// The Triple DES algorithm requires a trusted source of random bits
SecureRandom sr = new SecureRandom();

//Create a Triple DES key object specification from the raw data.
//Treat the bytes read from file as a hex string
DESedeKeySpec dks = new DESedeKeySpec(Hex.fromString(keyString));
// Create a key factory and use it to turn the DESedeKeySpec into
// a SecretKey object
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance( "DESede" );
SecretKey key = keyFactory.generateSecret( dks );

Cipher cipher = Cipher.getInstance("DESede/ECB/NoPadding");
// Initialize the cipher with the key
cipher.init( Cipher.ENCRYPT_MODE, key );


//Get the input data padded with 'F' in a byte array
byte[] data = Hex.fromString(XORResult);

// The actual encryption step

byte encryptedData[] = cipher.doFinal( data );

/**Triple DES Encryption End **/

//Convert the encrypted bytes to big int
BigInteger bCiph = new BigInteger(encryptedData);

//Dump the byte array to a temp string
tempString = Hex.dumpString(getMagnitude(bCiph));
tempString = tempString.trim();

//If output contains hex A-F convert to
//ASCII value of 3A-3F
//Get the output string in a byte array
byte outputStr[] = new byte[tempString.length()];
//Compare each byte for values A-F
for (int hexCnt=0;hexCnt<tempString.length();hexCnt++)
{
        outputStr[hexCnt] = (byte) tempString.charAt(hexCnt);
}

//Convert the output byte array to string
encryptedPin = new String(outputStr);

encryptedPin = encryptedPin.trim();

推荐答案

试试TripleDES类 [ ^ ]
