推荐答案

否-那是最好的方法.它允许您将他的密码保留为哈希，这意味着无法读取或还原该密码，并让用户获得一个新密码.您还应该为用户提供一些更改密码的机制，并让新"密码难以输入以鼓励他更改密码！

我个人使用Guid.NewGuid().ToString()生成新密码，但也有 ^ ]

no - that is the best way. It allows you to keep him password as a hash, which means that it can''t be read or restored, and lets the user get a new one. You should also provide some mechanism for the user to change his password, and also make the "new" password difficult to enter to encourage him to change it!

Personally, I use Guid.NewGuid().ToString() to generate the new password, but there is also the Membership.GeneratePassword method[^]

尝试以下操作:
恢复和更改密码

SqlMembershipProvider.GetPassword方法

Try the following:
Recovering and Changing Passwords

SqlMembershipProvider.GetPassword Method

试试这个

Try this

public static string GetPasswordHash(string password)
        {
            byte[] _bytePassword = ASCIIEncoding.ASCII.GetBytes(password.Trim());
            _bytePassword = new SHA1CryptoServiceProvider().ComputeHash(_bytePassword);

            //do convert it to string for display & storing in DB
            int i;
            StringBuilder sbOutput = new StringBuilder(_bytePassword.Length);
            for (i = 0; i < _bytePassword.Length - 1; i++)
            {
                //build string array from byte array
                sbOutput.Append(_bytePassword[i].ToString("X2"));//"X2" is used to convert byte array to string
            }
            return sbOutput.ToString();
        }
