本文实例讲述了C#实现Base64处理的加密解密,编码解码。分享给大家供大家参考,具体如下:
using System;
using System.Text;
namespace Common
{
/// <summary>
/// 实现Base64加密解密
/// 作者:周公
/// </summary>
public sealed class Base64
{
/// <summary>
/// Base64加密
/// </summary>
/// <param name="codeName">加密采用的编码方式</param>
/// <param name="source">待加密的明文</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;
}
/// <summary>
/// Base64加密,采用utf8编码方式加密
/// </summary>
/// <param name="source">待加密的明文</param>
/// <returns>加密后的字符串</returns>
public static string EncodeBase64( string source)
{
return EncodeBase64(Encoding.UTF8, source);
}
/// <summary>
/// Base64解密
/// </summary>
/// <param name="codeName">解密采用的编码方式,注意和加密时采用的方式一致</param>
/// <param name="result">待解密的密文</param>
/// <returns>解密后的字符串</returns>
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;
}
/// <summary>
/// Base64解密,采用utf8编码方式解密
/// </summary>
/// <param name="result">待解密的密文</param>
/// <returns>解密后的字符串</returns>
public static string DecodeBase64( string result)
{
return DecodeBase64(Encoding.UTF8, result);
}
}
}
希望本文所述对大家C#程序设计有所帮助。
