.Net 6.0：“AesManaged”已弃用：“派生的加密类型已过时。改为在基本类型上使用 Create 方法。

亲爱的社区成员！

帮助改进代码！要加密字符串（需要将机密数据保存到公共数据库），我使用该类：

public static class StringEncriptor
    {
        private static readonly byte[] KEY = Enumerable.Range(0, 32).Select(x => (byte)x).ToArray();

        public static string Encrypt (string text)
        {
            using AesManaged aes = new() { Key = KEY };
            using MemoryStream ms = new();
            ms.Write(aes.IV);
            using (CryptoStream cs = new(ms, aes.CreateEncryptor(), CryptoStreamMode.Write, true))
            {
                cs.Write(Encoding.UTF8.GetBytes(text));
            }
            return Convert.ToBase64String(ms.ToArray());
        }

        public static string Decrypt (string base64)
        {
            using MemoryStream ms = new(Convert.FromBase64String(base64));
            byte[] iv = new byte[16];
            ms.Read(iv);
            using AesManaged aes = new() { Key = KEY, IV = iv };
            using CryptoStream cs = new(ms, aes.CreateDecryptor(), CryptoStreamMode.Read, true);
            using MemoryStream output = new();
            cs.CopyTo(output);
            return Encoding.UTF8.GetString(output.ToArray());
        }
    }

它通常在 .Net 5.0 中解决并完全执行其功能。随着 .Net 6.0 的发布，我决定切换到它（该项目仍处于早期阶段，因此非常现实）。我遇到了这个警告：

SYSLIB0021  "AesManaged" является устаревшим: 'Derived cryptographic types are obsolete. Use the Create method on the base type instead.'

很明显，您需要使用父级的 Create 方法。请帮我理解...

提前致谢！！！

    非常感谢用户@Kotomi 的回答。他提出了正确的选择，我分享：

    public static class StringEncriptor
{
    private static readonly byte[] KEY = Enumerable.Range(0, 32).Select(x => (byte)x).ToArray();

    public static string Encrypt (string text)
    {
        using Aes aes = Aes.Create("AesManaged");
        aes.Key = KEY;
        using MemoryStream ms = new();
        ms.Write(aes.IV);
        using (CryptoStream cs = new(ms, aes.CreateEncryptor(), CryptoStreamMode.Write, true))
        {
            cs.Write(Encoding.UTF8.GetBytes(text));
        }
        return Convert.ToBase64String(ms.ToArray());
    }

    public static string Decrypt (string base64)
    {
        using MemoryStream ms = new(Convert.FromBase64String(base64));
        byte[] iv = new byte[16];
        ms.Read(iv);
        using Aes aes = Aes.Create("AesManaged");
        aes.Key = KEY;
        aes.IV = iv;
        using CryptoStream cs = new(ms, aes.CreateDecryptor(), CryptoStreamMode.Read, true);
        using MemoryStream output = new();
        cs.CopyTo(output);
        return Encoding.UTF8.GetString(output.ToArray());
    }
}
