[教学] Xamarin Studio PCLCrypto library AES Encrypt Decrypt

在xamarin你可以使用nuget来安装 PCLCrypto

取代 PHP MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC,  System.Security.Cryptography, RijndaelManaged, sample_visual_c_sharp_aes256_imcore_net

1.     public static string EncryptAES(string content, string password)
   
2.     {
   
3.         byte[] keyMaterial = Encoding.UTF8.GetBytes(password);
   
4.         byte[] data = Encoding.UTF8.GetBytes(content);
   
5.         byte[] iv = new byte[keyMaterial.Length];
   
6.         var provider = WinRTCrypto.SymmetricKeyAlgorithmProvider.OpenAlgorithm(SymmetricAlgorithm.AesCbcPkcs7);
   
7.         var key = provider.CreateSymmetricKey(keyMaterial);
   
8.         byte[] cipherText = WinRTCrypto.CryptographicEngine.Encrypt(key, data, iv);
   
9.         return Convert.ToBase64String(cipherText);
   
10.     }
    
11. 
    
12.     public static string DecryptAES(string content, string password)
    
13.     {
    
14.         byte[] keyMaterial = Encoding.UTF8.GetBytes(password);
    
15.         byte[] data = Convert.FromBase64String(content);
    
16.         byte[] iv = new byte[keyMaterial.Length];
    
17.         var provider = WinRTCrypto.SymmetricKeyAlgorithmProvider.OpenAlgorithm(SymmetricAlgorithm.AesCbcPkcs7);
    
18.         var key = provider.CreateSymmetricKey(keyMaterial);
    
19.         byte[] cipherText = WinRTCrypto.CryptographicEngine.Decrypt(key, data, iv);
    
20.         return Encoding.UTF8.GetString(cipherText, 0, cipherText.Length);
    
21.     }
