c# 跟IOS DES 加密问题

c# 跟IOS DES 加密问题

一、ios 加密代码
+(NSString *) encryptUseDES:(NSString *)clearText key:(NSString *)key
{
    NSData *data = [clearText dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    unsigned char buffer[1024];
    memset(buffer, 0, sizeof(char));
    size_t numBytesEncrypted = 0;
    CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt,
                                          kCCAlgorithmDES,
                                          kCCOptionPKCS7Padding| kCCOptionECBMode,
                                          [key UTF8String],
                                          kCCKeySizeDES,
                                          nil,
                                          [data bytes],
                                          [data length],
                                          buffer,
                                          1024,
                                          &numBytesEncrypted);
    
    NSString* plainText = nil;
    if (cryptStatus == kCCSuccess) {
        NSData *dataTemp = [NSData dataWithBytes:buffer length:(NSUInteger)numBytesEncrypted];
        plainText = [GTMBase64 stringByEncodingData:dataTemp];
    }else{
        NSLog(@"DES加密失败");
    }
    return plainText;
}

二、c#加密代码
public string EncryptData(string data)
        {
            byte[] keyBytes = Convert.FromBase64String(Key1);
            byte[] keyIV = Convert.FromBase64String(Key2);
            byte[] inputByteArray = Encoding.UTF8.GetBytes(data);
            DESCryptoServiceProvider provider = new DESCryptoServiceProvider();
            MemoryStream mStream = new MemoryStream();
            CryptoStream cStream = new CryptoStream(mStream, provider.CreateEncryptor(keyBytes, keyIV), CryptoStreamMode.Write);
            cStream.Write(inputByteArray, 0, inputByteArray.Length);
            cStream.FlushFinalBlock();
            return Convert.ToBase64String(mStream.ToArray());

        }
再附上安卓的代码 public String EncryptData(String Data) throws Exception {
        byte[] keyBytes = new BASE64Decoder().decodeBuffer(Key1);//ASCIIEncoding.ASCII.GetBytes(key);
        byte[] keyIV = new BASE64Decoder().decodeBuffer(Key2); //将12位密钥转为8位
        IvParameterSpec zeroIv = new IvParameterSpec(keyIV);
        //获得秘钥
        SecretKeySpec key = new SecretKeySpec(keyBytes, "DES");
        //实例化加密类Cipher      加密方式/工作模式/填充
        Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key, zeroIv);
        byte[] encryptedData = cipher.doFinal(Data.getBytes("UTF-8"));
        String encode = new String(Base64.encode(encryptedData, Base64.DEFAULT),"UTF-8");
        return encode;
    } 

NSString *ciphertext = nil;
    NSData *textData = [plainText dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    NSUInteger dataLength = [textData length];
    unsigned char buffer[1024];
    memset(buffer, 0, sizeof(char));
    size_t numBytesEncrypted = 0;
    NSData* key1Data = [key1 dataUsingEncoding:NSUTF8StringEncoding];
    NSString* key1Base64 = [key1Data base64EncodedStringWithOptions:0];
    NSData* key2Data = [key2 dataUsingEncoding:NSUTF8StringEncoding];
    NSString* key2Base64 = [key2Data base64EncodedStringWithOptions:0];
    
    
    CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmDES,kCCOptionPKCS7Padding|kCCOptionECBMode,(__bridge const void *)(key1Base64),kCCKeySizeDES,(__bridge const void *)(key2Base64),[textData bytes], dataLength,buffer, 1024,&numBytesEncrypted);
    if (cryptStatus == kCCSuccess) {
        NSData *data = [NSData dataWithBytes:buffer length:(NSUInteger)numBytesEncrypted];
        ciphertext = [GTMBase64 stringByEncodingData:data];
    }base64编码了以后还是不对啊
