C# DES加密后密文不是8的倍数，无法用python解密

mahosho · 发表于 2023-1-26 16:55

c#使用代码如下：
public static string EncryptDES(string encryptString, string encryptKey = "PCRGuild")
{
   MemoryStream memoryStream = new MemoryStream();
   GZipStream gzipStream = new GZipStream((Stream) memoryStream, System.IO.Compression.CompressionLevel.Optimal);
   byte[] bytes = Encoding.UTF8.GetBytes(encryptString);
   gzipStream.Write(bytes, 0, bytes.Length);
   gzipStream.Dispose();
   string base64String = Convert.ToBase64String(memoryStream.ToArray());
   memoryStream.Dispose();
   return base64String;
}
加密后密文如下：
