AES加密和解密 [英] AES Encrypt and Decrypt

问题描述

这是我的.net加密：

  public static byte [] AES_Encrypt（byte [] bytesToBeEncrypted，byte [] passwordBytes）
 {
 byte [] encryptedBytes = null; 
 
 byte [] saltBytes = new byte [] {1，2，3，4，5，6，7，8}; 
 
使用（MemoryStream ms = new MemoryStream（））
 {
 using（RijndaelManaged AES = new RijndaelManaged（））
 {
 AES.KeySize = 256; 
 AES.BlockSize = 128; 
 
 var key = new Rfc2898DeriveBytes（passwordBytes，saltBytes，1000）; 
 AES.Key = key.GetBytes（AES.KeySize / 8）; 
 AES.IV = key.GetBytes（AES.BlockSize / 8）; 
 
 AES.Mode = CipherMode.CBC; 
 
使用（var cs = new CryptoStream（ms，AES.CreateEncryptor（），CryptoStreamMode.Write））
 {
 cs.Write（bytesToBeEncrypted，0，bytesToBeEncrypted.Length） ; 
 cs.Close（）; 
} 
 encryptedBytes = ms.ToArray（）; 
} 
} 
 
返回encryptedBytes; 
} 
  

我需要在swift中解密功能。​​

解决方案

我找到了解决方案，这是一个很好的库。

跨平台256位AES加密/解密

此项目包含256位AES加密的实现，适用于所有平台（C＃，iOS，Android）。其中一个关键目标是使AES能够在所有平台上实现简单的实现。

支持平台：
iOS，
Android，
Windows（C＃）。

I write an application by swift, i need AES Encrypt and Decrypt functionality, i received encrypted data from another .Net solution, but i can't find something to do it.

This is my .net Encryption:

 public static byte[] AES_Encrypt(byte[] bytesToBeEncrypted, byte[] passwordBytes)
    {
        byte[] encryptedBytes = null;

        byte[] saltBytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };

        using (MemoryStream ms = new MemoryStream())
        {
            using (RijndaelManaged AES = new RijndaelManaged())
            {
                AES.KeySize = 256;
                AES.BlockSize = 128;

                var key = new Rfc2898DeriveBytes(passwordBytes, saltBytes, 1000);
                AES.Key = key.GetBytes(AES.KeySize / 8);
                AES.IV = key.GetBytes(AES.BlockSize / 8);

                AES.Mode = CipherMode.CBC;

                using (var cs = new CryptoStream(ms, AES.CreateEncryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(bytesToBeEncrypted, 0, bytesToBeEncrypted.Length);
                    cs.Close();
                }
                encryptedBytes = ms.ToArray();
            }
        }

        return encryptedBytes;
    }

I need to decrypt function in swift.

解决方案

I found the solution, it is a good library.

Cross platform 256bit AES encryption / decryption.

This project contains the implementation of 256 bit AES encryption which works on all the platforms (C#, iOS, Android). One of the key objective is to make AES work on all the platforms with simple implementation.

Platforms Supported: iOS , Android , Windows (C#).
