加密字符串AES Windows Phone 8.1 [英] Encrypt String AES Windows Phone 8.1

问题描述

我正在制作一个需要加密字符串的应用程序。
我是AES加密的新功能。

我必须在服务器上运行的代码进行加密。

  public static string Encrypt（string text，byte [] key，byte [] iv，int keysize = 128，int blocksize = 128，CipherMode cipher = CipherMode.CBC，PaddingMode padding = PaddingMode.PKCS7）
 {
 AesCryptoServiceProvider aes = new AesCryptoServiceProvider（）; 
 aes.BlockSize = blocksize; 
 aes.KeySize = keysize; 
 aes.Mode = cipher; 
 aes.Padding = padding; 
 
 byte [] src = Encoding.UTF8.GetBytes（text）; 
 using（ICryptoTransform encrypt = aes.CreateEncryptor（key，iv））
 {
 byte [] dest = encrypt.TransformFinalBlock（src，0，src.Length）; 
 encrypt.Dispose（）; 
 return Convert.ToBase64String（dest）; 
} 
} 
  

我已经有了这个，有一个图书馆Bouncy Castle，但是我似乎找不到一个简单的例子。

  byte [] key = Encoding.UTF8.GetBytes（[SECRETKEY ]）; 
 byte [] iv = Encoding.UTF8.GetBytes（[IV]）; 
 var cipher = CipherUtilities.GetCipher（AES / CBC / PKCS7Padding）; 
 
 cipher.Init（true，new KeyParameter（key））; 
  

如果可以帮助我也有运行Android客户端的代码。
让我知道，然后我可以发表。

解决方案

你可以使用PCLCrypto库，有一个nuget包可用（Install-Package PclCrypto）

从 https://github.com/AArnott/PCLCrypto/wiki/Crypto-Recipes ：

执行AES加密/解密

  byte [] keyMaterial; 
 byte [] data; 
 var provider = WinRTCrypto.SymmetricKeyAlgorithmProvider.OpenAlgorithm（SymmetricAlgorithm.AesCbcPkcs7）; 
 var key = provider.CreateSymmetricKey（keyMaterial）; 
 byte [] iv = null; //这是可选的，但加密和解密两者必须相同。
 byte [] cipherText = WinRTCrypto.CryptographicEngine.Encrypt（key，data，iv）; 
 byte [] plainText = WinRTCrypto.CryptographicEngine.Decrypt（key，cipherText，iv）; 
  

cipherText变量是加密数据，plainText是再次解密的加密变量

I'm making an app which will need to encrypt a string. I'm completely new to AES encryption.

I have to code that runs on the server to encrypt.

public static string Encrypt(string text, byte[] key, byte[] iv, int keysize = 128, int blocksize = 128, CipherMode cipher = CipherMode.CBC, PaddingMode padding = PaddingMode.PKCS7)
{
    AesCryptoServiceProvider aes = new AesCryptoServiceProvider();
    aes.BlockSize = blocksize;
    aes.KeySize = keysize;
    aes.Mode = cipher;
    aes.Padding = padding;

    byte[] src = Encoding.UTF8.GetBytes(text);
    using (ICryptoTransform encrypt = aes.CreateEncryptor(key, iv))
    {
        byte[] dest = encrypt.TransformFinalBlock(src, 0, src.Length);
        encrypt.Dispose();
        return Convert.ToBase64String(dest);
    }
}

I already have this, with a library Bouncy Castle, but I can't seem to find a simple example.

byte[] key = Encoding.UTF8.GetBytes("[SECRETKEY]");
            byte[] iv = Encoding.UTF8.GetBytes("[IV]");
            var cipher = CipherUtilities.GetCipher("AES/CBC/PKCS7Padding");

            cipher.Init(true, new KeyParameter(key));

If it can help I also have the code which runs an Android client. Let me know then I can post it.

解决方案

You can use the PCLCrypto library, there's a nuget package available (Install-Package PclCrypto)

From https://github.com/AArnott/PCLCrypto/wiki/Crypto-Recipes:

Perform AES encryption/decryption

byte[] keyMaterial;
byte[] data;
var provider = WinRTCrypto.SymmetricKeyAlgorithmProvider.OpenAlgorithm(SymmetricAlgorithm.AesCbcPkcs7);
var key = provider.CreateSymmetricKey(keyMaterial);
byte[] iv = null; // this is optional, but must be the same for both encrypting and decrypting
byte[] cipherText = WinRTCrypto.CryptographicEngine.Encrypt(key, data, iv);
byte[] plainText = WinRTCrypto.CryptographicEngine.Decrypt(key, cipherText, iv);

The cipherText variable is the encrypted data, plainText is the encrypted variable decrypted again
