C#编程语言之MD5加密的两种方式

/// <summary>
/// MD5字符串加密

/// <param name="txt"></param>
/// <returns>加密后字符串</returns>
public static string GenerateMD5(string txt)
{
    using (MD5 mi = MD5.Create())
    {
        byte[] buffer = Encoding.Default.GetBytes(txt);
        //开始加密
        byte[] newBuffer = mi.ComputeHash(buffer);
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < newBuffer.Length; i++)
        {
            sb.Append(newBuffer[i].ToString("x2"));
        }
        return sb.ToString();
    }
}
