如何在ASP.NET Identity中使用ASP.NET会员数据库？

 2023-02-16    340  

问题描述

我有几个旧的ASP.NET Web应用程序，它们共享ASP.NET成员资格的数据库.我想利用.NET核心和IdentityServer4的微服务架构4，并在新的微服务生态系统中使用SIDESSITY服务器使用现有的ASP.NET成员用户存储，但是.NET Core似乎不支持ASP.NET成员资格全部.

我目前有一个概念证明，涉及Web API，Identity Server和MVC Web应用程序作为我的客户端.身份服务器实现了IdentityUser的子类，并实现了Iuserstore/iuserpasswordstore/iuseremailstore，以使其适应我现有数据库中的ASP.NET成员表.我可以注册新用户并通过我的POC MVC客户端应用程序登录，但是这些用户无法登录我的旧应用程序.相反，在旧应用程序中注册的用户无法登录我的POC MVC客户端.我之所以认为是因为我的ipasswordhasher的实现与我的旧应用程序中的ASP.NET成员资格相同.

如何在ASP.NET Identity中使用ASP.NET会员数据库？

.

以下是我的代码.对我可能做错的事情的任何洞察力都将不胜感激.安全性和密码学不是我的强项.

推荐答案

我的一位同事能够帮助我.下面是哈希功能的外观.有了此更改，ASP.NET身份能够回到现有的ASP.NET成员数据库上.

private void HashPassword(string password, out string passwordHash, ref string passwordSalt)
    {
        byte[] passwordBytes = Encoding.Unicode.GetBytes(password);
        byte[] saltBytes = null;

        if (!string.IsNullOrEmpty(passwordSalt))
        {
            saltBytes = Convert.FromBase64String(passwordSalt);
        }
        else
        {
            saltBytes = new byte[128 / 8];
            using (var rng = RandomNumberGenerator.Create())
            {
                rng.GetBytes(saltBytes);
            }
        }

        byte[] totalBytes = new byte[saltBytes.Length + passwordBytes.Length];
        Buffer.BlockCopy(saltBytes, 0, totalBytes, 0, saltBytes.Length);
        Buffer.BlockCopy(passwordBytes, 0, totalBytes, saltBytes.Length, passwordBytes.Length);

        using (SHA1 hashAlgorithm = SHA1.Create())
        {
            passwordHash = Convert.ToBase64String(hashAlgorithm.ComputeHash(totalBytes));
        }

        passwordSalt = Convert.ToBase64String(saltBytes);
    }
