ASP.NET下用MD5加密密码

 

public string encryptyPassword(string in_pass)

            {

                  string originStr = in_pass;

                  string securityStr;

 

                  char[] chars = originStr.ToCharArray();

                  byte[] inBytes = new byte[chars.Length];

                  for(int i = 0; i < inBytes.Length; i ++)

                        inBytes[i] = Convert.ToByte(chars[i]);

                 

                  MD5CryptoServiceProvider md = new MD5CryptoServiceProvider();

                  byte[] outBytes = md.ComputeHash(inBytes);

 

                  securityStr = BitConverter.ToString(outBytes);

                 

                return securityStr ;

            }
