C Realizes the Encryption Decryption Encoding Decoding Example of Base64 Processing

This article describes the example of C # to achieve Base64 processing of encryption, decryption, encoding and decoding. Share it for your reference, as follows:

using System;
using System.Text;
namespace Common
{

    /// <param name="codeName"> Encoding method used for encryption </param>
    /// <param name="source"> Clear text to be encrypted </param>
    /// <returns></returns>
    public static string EncodeBase64(Encoding encode, string source)
    {
      byte[] bytes = encode.GetBytes(source);
      try
      {
        encode = Convert.ToBase64String(bytes);
      }
      catch
      {
        encode = source;
      }
      return encode;
    }

    public static string EncodeBase64(string source)
    {
      return EncodeBase64(Encoding.UTF8, source);
    }
    /// <summary>

    public static string DecodeBase64(Encoding encode, string result)
    {
      string decode = "";
      byte[] bytes = Convert.FromBase64String(result);
      try
      {
        decode = encode.GetString(bytes);
      }
      catch
      {
        decode = result;
      }
      return decode;
    }

    public static string DecodeBase64(string result)
    {
      return DecodeBase64(Encoding.UTF8, result);
    }
  }
}
