AES 加密和解密 [英] AES Encrypt and Decrypt

问题描述

我通过 swift 编写了一个应用程序，我需要 AES 加密和解密功能，我从另一个 .Net 解决方案收到了加密数据，但我找不到可以做的事情.

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.

这是我的 .net 加密:

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;
    }

我需要快速解密函数.

推荐答案

我找到了解决方案，它是一个很好的库.

I found the solution, it is a good library.

跨平台 256 位 AES 加密/解密.

Cross platform 256bit AES encryption / decryption.

该项目包含适用于所有平台(C#、iOS、Android)的 256 位 AES 加密的实现.关键目标之一是通过简单的实现使 AES 在所有平台上工作.

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.

支持的平台:IOS ,安卓 ，Windows (C#).

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