asp.netMD5加密函数(c#)

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

利用下面的方法,可直接输入数据,反回md5加密后的代码

/// <summary>
/// 用md5加密
/// </summary>
/// <param name="Sourcein">输入的数据</param>
/// <returns></returns>
public static string MD5(string Sourcein)
{
   MD5CryptoServiceProvider MD5CSP = new MD5CryptoServiceProvider();
   byte[] MD5Source = System.Text.Encoding.UTF8.GetBytes(Sourcein);
   byte[] MD5Out = MD5CSP.ComputeHash(MD5Source);
   return Convert.ToBase64String(MD5Out);
}

以上只是适用于.net的MD5加密,但是现在很多公司处于asp转asp.net的阶段,为了不改动原来的教大的用户数据库,我们需要找到一种跟asp的md5加密后相同的结果,下面的代码是我曾经用过的,给出来大家参考:黄色部分代码
