使用AES /十六进制将ColdFusion加密转换为C#

与这篇文章中的主题相关：
Converting Coldfusion encryption code to C#

您将如何进行此转换：

<!--- valueToEncrypt = "34245678", key = "TJhKuhjyx/87giutBNHh9t==" --->
<cfset output = Encrypt( valueToEncrypt, key, "AES", "Hex")>

这是我在C#中尝试过的方法：

byte[] plainText = Encoding.UTF8.GetBytes(TextToEncrypt);
byte[] key = Convert.FromBase64String(encryptionKey);
RijndaelManaged algorithm = new RijndaelManaged();
algorithm.Mode = CipherMode.ECB;
algorithm.Padding = PaddingMode.PKCS7;
algorithm.BlockSize = 128;
algorithm.KeySize = 128;
algorithm.Key = key;
string result;
using (ICryptoTransform encryptor = algorithm.CreateEncryptor())
{
    using (MemoryStream memoryStream = new MemoryStream())
    {
        using (CryptoStream cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write))
        {
            cryptoStream.Write(plainText, 0, plainText.Length);
            cryptoStream.FlushFinalBlock();
            result = Convert.ToBase64String(memoryStream.ToArray());
        }
    }
}

return result;

ColdFusion结果：

04197FAA3C9C030660A6377E44F77C4E

C#结果：

BBl/qjycAwZgpjd+RPd8Tg==

解决方法:

实际上结果是相同的.它们只是编码不同.两者都对输入进行加密并生成二进制文件,然后对结果进行编码,以便于存储和传输. ColdFusion代码仅选择将这些字节编码为“十六进制”,而C#代码使用“ base64”.尽管结果看起来可能有所不同,但它们仍表示相同的值.例如,请注意,如果将C#结果(base64)解码为二进制和re-encode it as hex,它是否与CF结果匹配？

C#(将结果从base64转换为十六进制)

byte[] decoded = Convert.FromBase64String("BBl/qjycAwZgpjd+RPd8Tg==");
string resultAsHex = (BitConverter.ToString(decoded).Replace("-", string.Empty));

结果：

04197FAA3C9C030660A6377E44F77C4E 

话虽如此,如果您需要在两边都产生相同的编码字符串,则可以：

A.将C#代码更改为encode the result as hex,而不是base64

    result =  BitConverter.ToString(memoryStream.ToArray()).Replace("-", string.Empty);

要么

B.更改CF代码以使用base64编码：

    <cfset output = Encrypt( valueToEncrypt, key, "AES", "Base64")>
