Question

我有一个加密 - 解密方案，如下所示。

// [清除文本ID字符串作为输入] - [（ASCII GetByte）+编码] - [编码为字节数组] - [数据库列在VarBinary中] - [将byte []作为VarBinary参数传递到SP进行比较]

// [在数据库中存储为VarBinary的ID] - [读取为字节数组] - [（解密为字节数组）+编码+（ASCII获取字符串）] - 在UI中显示为字符串

我的问题在于解密方案。解密后我得到一个字节数组。之后我正在进行编码（IBM037）。这是对的吗？上面显示的流程有什么问题吗？

private static byte[] GetEncryptedID(string id)
{
    Interface_Request input = new Interface_Request();
    input.RequestText = Encodeto64(id);
    input.RequestType = Encryption;

    ProgramInterface inputRequest = new ProgramInterface();
    inputRequest.Test_Trial_Request = input;

    using (KTestService operation = new KTestService())
    {
        return ((operation.KTrialOperation(inputRequest)).Test_Trial_Response.ResponseText);
    }
}


private static string GetDecryptedID(byte[] id)
{
    Interface_Request input = new Interface_Request();
    input.RequestText = id;
    input.RequestType = Decryption;

    ProgramInterface request = new ProgramInterface();
    request.Test_Trial_Request = input;

    using (KTestService operationD = new KTestService())
    {
            ProgramInterface1 response = operationD.KI014Operation(request);
            byte[] decryptedValue = response.ICSF_AES_Response.ResponseText;
            Encoding sourceByteFormat = Encoding.GetEncoding("IBM037");
            Encoding destinationByteFormat = Encoding.ASCII;

            //Convert from one byte format to other (IBM to ASCII)
            byte[] ibmEncodedBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat,decryptedValue);
            return System.Text.ASCIIEncoding.ASCII.GetString(ibmEncodedBytes);

        }
    }

    private static byte[] EncodeTo64(string toEncode)
    {
        byte[] dataInBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
        Encoding destinationByteFormat = Encoding.GetEncoding("IBM037");
        Encoding sourceByteFormat = Encoding.ASCII;

        //Convert from one byte format to other (ASCII to IBM)
        byte[] asciiBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat, dataInBytes);
        return asciiBytes;
    }

Answer 1

我找到了答案 - 解密过程，解密后我将IBM037字节转换为ASCII字节。这就是为什么有编码进来。我已经更新了问题中的代码（有更多的解释变量）

这个解密需要编码吗？
