在机器密钥更改期间维护 ASP.Net 成员密码

发布于 2024-09-30 04:25:33 字数 55 浏览 4 评论 0原文

是否有实用程序或代码示例可以使用旧密钥解密,然后使用新密钥为 ASP.Net 会员用户加密密码?

Is there an utility or code sample that can decrypt with the old key, and then encrypt passwords with a new key for ASP.Net membership users?

提到的解决方法都不适合我。
我的解决方案如下。它首先以明文形式存储密码,然后使用新的 MachineKey 再次对其进行重新加密。

机器密钥更改

None of the workarounds mentioned worked for me.
My solution is below. It involves first storing passwords in clear text and then reencrypting them again with new MachineKey.

Machine Key Change

这是我对解决方案的最佳猜测,但我还没有机会测试它。它依赖于当前提供程序的以下设置:

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

它还假设新的机器密钥已在配置文件中。

创建以下类(感谢 mootinator 的帮助)

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 });
        }
    }
}

在您的 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
}

让我知道这是否适合您。

This is my best guess at a solution, but I haven't had a chance to test it. It relies on the following settings for your current provider:

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

It also assumes that the new machinekey is already in the config file.

Create the following class (thanks to mootinator for the jumpstart on this)

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 });
        }
    }
}

In your web.config:

<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>

Change the passwords with the following code:

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
}

Let me know if that works for you.

我认为您可以通过动态设置密钥来做到这一点:

您可能必须扩展 SqlMembershipProvider (或您使用的任何内容)才能访问 protected DecryptPassword 方法。

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

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

I think you could do this by setting the key on the fly:

You might have to extend the SqlMembershipProvider (or whatever you use) to get access to the protected DecryptPassword method.

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

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