C# AES-128-CBC 加密

本文介绍: string s1 = AESEncode r.AesEnc ry p t(“abc d123哪里”);Con sole.Wr i t eLin e(“加密:” + s1);Con sole.Wr i t eLin e(“解密:” + s2);

一、加密

        /// &lt;summary&gt;
        /// 加密
        /// &lt;/summary&gt;
        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 = “nsm kindi”.PadRight(16);

string s1 = AESEncoder.AesEncrypt(“abcd123哪里”);
Con sole.WriteLine(“加密:” + s1);

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

Console.ReadKey();

}
