Question

我创建了一些用于加密和解密的方法和类，并为AES算法生成了随机密钥。现在，当我想使用随机密钥进行加密时，我的解密结果和输入字符串不匹配。并且当我使用指定的密钥时（不使用随机）匹配此结果，但在解密结果字符串

后有“ \ v”表达式

我的随机密钥生成器工厂：

public class KeyGeneratorFactory
{
    public static string keyGeneratorFactory()
    {
        string keyGenerator = string.Empty;
        Random random = new Random();
        int rdmkey = random.Next();
        keyGenerator = "llkj322km,n3kl4nnl@" + Convert.ToString(rdmkey);
        return keyGenerator;
    }
}

这是我的加密方法

public static string EncryptPass(string password)
{
    if (password == null)
    {
        return null;
    }
    else
    {
        byte[] bytePassword = Encoding.UTF8.GetBytes(password);
        using (Aes aesEncryptor = Aes.Create())
        {
            Rfc2898DeriveBytes rf = new Rfc2898DeriveBytes(KeyGeneratorFactory.keyGeneratorFactory(), new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
            aesEncryptor.Key = rf.GetBytes(32);
            aesEncryptor.IV = rf.GetBytes(16);
            using (MemoryStream memoryStream = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(memoryStream, aesEncryptor.CreateEncryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(bytePassword, 0, bytePassword.Length);
                    cs.Close();
                }
                password = Convert.ToBase64String(memoryStream.ToArray());
            }
        }
        return password;
    }
}

这是我的解密方法

public static string DecryptPass(string cypherPassword)
{
    if (cypherPassword == null)
    {
        return null;
    }
    else
    {
        byte[] cypherPasswordByte = Convert.FromBase64String(cypherPassword);
        using (Aes aesDecryptor = Aes.Create())
        {
            aesDecryptor.Padding = PaddingMode.Zeros;
            Rfc2898DeriveBytes rf = new Rfc2898DeriveBytes(KeyGeneratorFactory.keyGeneratorFactory(), new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
            aesDecryptor.Key = rf.GetBytes(32);
            aesDecryptor.IV = rf.GetBytes(16);
            using (MemoryStream memoryStream = new MemoryStream())
            {
                using (CryptoStream cs = new CryptoStream(memoryStream, aesDecryptor.CreateDecryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(cypherPasswordByte, 0, cypherPasswordByte.Length);
                }
                cypherPassword = Encoding.UTF8.GetString(memoryStream.ToArray());
            }
        }
        return cypherPassword;

    }
}

我想知道如何在字符串后清除“ \ v”，以及如何在不为用户保存数据库的情况下将随机密钥用于AES算法。我可以吗？我不喜欢使用指定的密钥

我在使用C＃的AES算法中使用随机密钥加密和解密密码时遇到问题
