我有一个通过以下脚本进行身份验证的网站，并生成一个以$ P $ B开头的密码...
public static function hashPassword($plainPassword)

// use openwall.com phpass class

}

$hasher = new PasswordHash(8, true);

通过以下方式检查您的密码：

经过多次尝试，我们成功了。解决方法如下： 登录按钮：
string userLogat = tbUser.Text;
MySqlConnection sqlcon = new MySqlConnection(@"server=xx.xx.xx.xx;user id=user;password=password;persistsecurityinfo=False;database=website;sslmode=None;");
string query = "Select * from users Where username= '" + tbUser.Text + "'";
MySqlDataAdapter sda = new MySqlDataAdapter(query, sqlcon);
DataTable dtbl = new DataTable();
sda.Fill(dtbl);
if (dtbl.Rows.Count == 1)
{
string savedPasswordHash = dtbl.Rows[0][3].ToString();
if (CryptSharp.Crypter.CheckPassword(tbPass.Text, savedPasswordHash))
{
MessageBox.Show($"Wellcome {tbUser.Text} !");
FormMain openMain = new FormMain(userLogat);
openMain.Show();
this.Hide();
}
else
{
MessageBox.Show($"Parola pentru userul {userLogat} nu exista valida.");
}
}
else
{
MessageBox.Show($"Username incorect!");
}
sqlcon.Close();
