asp.net – 将密码格式从加密更改为哈希

>在我的web.config中创建两个MembershipProviders,一个用于加密密码,一个用于散列.
>循环使用加密密码提供程序的所有用户. (SqlMembershipProvider.GetAllUsers)
>使用加密密码提供程序获取用户密码. (MembershipUser.GetPassword)
>使用散列密码提供程序将用户密码更改为相同的密码. (MembershipUser.ChangePassword)

那就是这样的：

<membership defaultProvider="HashedProvider">
        <providers>
            <clear />
            <add name="HashedProvider" connectionStringName="MembershipConnectionString" enablePasswordRetrieval="false"  requiresQuestionAndAnswer="false" applicationName="MyApp" passwordFormat="Hashed"  type="System.Web.Security.SqlMembershipProvider" />
            <add name="EncryptedProvider" connectionStringName="MembershipConnectionString" enablePasswordRetrieval="true" requiresQuestionAndAnswer="false" applicationName="MyApp" passwordFormat="Encrypted" type="System.Web.Security.SqlMembershipProvider" />
        </providers>
    </membership>

码：

SqlMembershipProvider hashedProvider = (SqlMembershipProvider)Membership.Providers["HashedProvider"];
SqlMembershipProvider encryptedProvider = (SqlMembershipProvider)Membership.Providers["EncryptedProvider"];

int unimportant;
foreach (MembershipUser user in encryptedProvider.GetAllUsers(0,Int32.MaxValue,out unimportant ))
{
    hashedProvider.ChangePassword(user.UserName,user.GetPassword(),user.GetPassword());
}
