我想将查询字符串中的一个字段从 asp .net 传递到 Apex 。我想加密字段的值，然后在查询字符串中传递它。我不知道如何解决这个问题，是否有相同的示例代码/链接？基本上我想在 C# 中加密并使用 Apex 解密。
在 C# 中
static string key = "eU5WzoFgU4n8Apu5PYxcNGRZswRDZJWDEMdbQVU85gw=";
static string IV = "9ehY9gYtfIGlLRgwqg6F2g==";
static void Main(string[] args)
{
string source = "test";
string encrypted = EncryptStringToBytes_Aes(source, Convert.FromBase64String(key), Convert.FromBase64String(IV));
Console.ReadLine();
}
static string EncryptStringToBytes_Aes(string plainText, byte[] Key, byte[] IV)
{
// Check arguments.
if (plainText == null || plainText.Length <= 0)
throw new ArgumentNullException("plainText");
if (Key == null || Key.Length <= 0)
throw new ArgumentNullException("Key");
if (IV == null || IV.Length <= 0)
throw new ArgumentNullException("Key");
string encrypted;
// Create an AesManaged object
// with the specified key and IV.
using (AesManaged aesAlg = new AesManaged())
{
aesAlg.Key = Key;
aesAlg.IV = IV;
// Create a decrytor to perform the stream transform.
ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);
// Create the streams used for encryption.
using (MemoryStream msEncrypt = new MemoryStream())
{
using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
{
using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
{
//Write all data to the stream.
swEncrypt.Write(plainText);
}
encrypted = Convert.ToBase64String(msEncrypt.ToArray());// ToArray();
}
}
}
// Return the encrypted bytes from the memory stream.
return encrypted;
}
在顶点：
string cryptoKey='eU5WzoFgU4n8Apu5PYxcNGRZswRDZJWDEMdbQVU85gw=';
String det= System.currentPageReference().getParameters().get('Det');
Blob decryptedData = Crypto.decryptWithManagedIV('AES256', EncodingUtil.base64Decode(cryptoKey), EncodingUtil.base64Decode(det));
但这不起作用，decryptedData.toString() 不是“测试”（原文）。我如何解密回来？
