c# - 从 System.Security.Cryptography 获取相同的加密字符串

Question

我想在下面的加密代码中进行更改，以便它一次又一次地为给定文本提供相同的加密字符串。

例如输入字符串：“test”

输出加密字符串：“@#$#@$@#$SDFDSF”

如果我一次又一次地输入“测试”，输出应该是相同的。

public static string Encrypt(string text, bool encryptSame = false)
    {
        var key = Encoding.UTF8.GetBytes("E546C8DF278CD5931069B522E695D4F3");

        using (var aesAlg = Aes.Create())
        {
            if (encryptSame)
            {
                aesAlg.Padding = PaddingMode.Zeros;
                aesAlg.Mode = CipherMode.ECB;
            }

            using (var encryptor = aesAlg.CreateEncryptor(key, aesAlg.IV))
            {
                
                using (var msEncrypt = new MemoryStream())
                {
                    using (var csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                    using (var swEncrypt = new StreamWriter(csEncrypt))
                    {
                        swEncrypt.Write(text);
                    }

                    var iv = aesAlg.IV;

                    var decryptedContent = msEncrypt.ToArray();

                    var result = new byte[iv.Length + decryptedContent.Length];

                    Buffer.BlockCopy(iv, 0, result, 0, iv.Length);
                    Buffer.BlockCopy(decryptedContent, 0, result, iv.Length, decryptedContent.Length);

                    return Convert.ToBase64String(result);
                }
            }
        }
    }
