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();
