C# AES-128-CBC 加密

一、加密

        /// <summary>
        /// 加密
        /// </summary>
        public static string AesEncrypt(string toEncrypt)
        {
            byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt);
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(Key);//注意编码格式(utf8编码 UTF8Encoding)
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(Iv);

            RijndaelManaged rDel = new RijndaelManaged();
            rDel.KeySize = 128;
            rDel.BlockSize = 128;
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            ICryptoTransform cTransform = rDel.CreateEncryptor();//加密
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);


        }

二、解密

        /// <summary>
        /// 解密
        /// </summary>
        public static string AesDecrypt(string toDecrypt)
        {
            string key32 = Key.PadRight(16);

            byte[] toEncryptArray = Convert.FromBase64String(toDecrypt);
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(Key);//注意编码格式(utf8编码 UTF8Encoding)
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(Iv);

            RijndaelManaged rDel = new RijndaelManaged();
            rDel.KeySize = 128;
            rDel.BlockSize = 128;
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;

            ICryptoTransform cTransform = rDel.CreateDecryptor();//解密
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return UTF8Encoding.UTF8.GetString(resultArray);
        }

三、具体使用

     static void Main(string[] args)
        {
            AESEncoder.Key = "nsmkindi".PadRight(16);

            string s1 = AESEncoder.AesEncrypt("abcd123哪里");
            Console.WriteLine("加密:" + s1);

            string s2 = AESEncoder.AesDecrypt(s1);
            Console.WriteLine("解密:" + s2);

            Console.ReadKey();

        }

四、完结。
