des加密 c++ java

谁可以把下面的java des加密算法写成c++的，要求java加密的可以用c++解密
c++加密的可以用java解密哦

private String encryptData(String retData) {
if (!encryptFlag) {
return retData;
}
String returnData = "";
try {
String oriDataValue = retData;
BASE64Decoder base64decoder = new BASE64Decoder();
BASE64Encoder base64encoder = new BASE64Encoder();
byte[] keyBytes = base64decoder.decodeBuffer("liana");
KeyGenerator generator = KeyGenerator.getInstance("DES");
generator.init(new SecureRandom(keyBytes));
Key key = generator.generateKey();
Cipher cipher = Cipher.getInstance("DES" + "/" + "ECB" + "/"
+ "PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] encryptBytes = cipher
.doFinal(oriDataValue.getBytes("UTF-8"));
String encryptStr = base64encoder.encode(encryptBytes);
