在更改计算机密钥期间维护ASP.Net成员身份密码

上面提到的解决办法都不适合我。 我的解决方案如下。它包括首先以明文存储密码,然后用新的MachineKey重新加密密码。

Machine Key Change

enablePasswordRetrieval="true" requiresQuestionAndAnswer="false" passwordFormat="Encrypted"

它还假设新的machinekey已经在配置文件中。

创建下面的类(感谢mootinator在这里的启动)

using System.Reflection;
using System.Web.Configuration;
using System.Web.Security;
namespace MyNamespace
{
    public class MySqlMembershipProvider : SqlMembershipProvider
    {
        protected override byte[] DecryptPassword(byte[] encodedPassword)
        {
            MachineKeySection section = (MachineKeySection)WebConfigurationManager.GetSection("system.web/machineKey");
            section.DecryptionKey = "oldkey"; // TODO: Set your old key here

            MethodInfo method = typeof(MachineKeySection).GetMethod("EncryptOrDecryptData", BindingFlags.Instance | BindingFlags.NonPublic);

            return (byte[])method.Invoke(section, new object[] { encodedPassword, null, 0, encodedPassword.Length, 0, false, false });
        }
    }
}

在web.config中:

<membership defaultProvider="DefaultSqlMembershipProvider">
  <providers>
    <clear/>
    <add name="DefaultSqlMembershipProvider" connectionStringName="MembershipConnectionString" enablePasswordRetrieval="true" requiresQuestionAndAnswer="false" applicationName="TODO" passwordFormat="Encrypted" type="System.Web.Security.SqlMembershipProvider"/>
    <add name="MySqlMembershipProvider" connectionStringName="MembershipConnectionString" enablePasswordRetrieval="true" requiresQuestionAndAnswer="false" applicationName="TODO" passwordFormat="Encrypted" type="MyNamespace.MySqlMembershipProvider"/>
  </providers>
</membership>

使用以下代码更改密码:

MembershipProvider retrievePasswordProvider = Membership.Providers["MySqlMembershipProvider"];

foreach (MembershipUser user in Membership.GetAllUsers())
{
    MembershipUser retrievePassworedUser = retrievePasswordProvider.GetUser(user.UserName, false);
    string password = retrievePassworedUser.GetPassword(); // get password using old key

    user.ChangePassword(password, password); // change password to same password using new key
}

如果这对你有用,请告诉我。

我想你可以在飞行中设定钥匙:

你可能需要延长 SqlMembershipProvider (或任何你使用的)进入 protected DecryptPassword 方法。

    MachineKeySection section = (MachineKeySection)WebConfigurationManager.GetSection("system.web/machineKey");

section.DecryptionKey = "old";
// Read old password
section.DecryptionKey = "new";
// Store new password
