1、项目中引用命名空间
using System.Security.Cryptography;
using System.Text;
2、.NET Core(C#)的AES加解密实现代码
using System;using System.IO;using System.Security.Cryptography;using System.Text;namespace ConsoleApp2{ class Program { /// /// AES加密算法 /// /// 明文字符串 /// 字符串 public static string EncryptByAES(string input, string key, string iv) { if (string.IsNullOrWhiteSpace(input)) { return input; } using (RijndaelManaged rijndaelManaged = new RijndaelManaged()) { rijndaelManaged.Mode = CipherMode.CBC; rijndaelManaged.Padding = PaddingMode.PKCS7; rijndaelManaged.FeedbackSize = 128; rijndaelManaged.Key = Encoding.UTF8.GetBytes(key); rijndaelManaged.IV = Encoding.UTF8.GetBytes(iv); ICryptoTransform encryptor = rijndaelManaged.CreateEncryptor(rijndaelManaged.Key, rijndaelManaged.IV); using (MemoryStream msEncrypt = new MemoryStream()) { using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write)) { using (StreamWriter swEncrypt = new StreamWriter(csEncrypt)) { swEncrypt.Write(input); } byte[] bytes = msEncrypt.ToArray(); return Convert.ToBase64String(bytes); } } } } /// /// AES解密 /// /// 密文字节数组 /// 返回解密后的字符串 public static string DecryptByAES(string input, string key, string iv) { if (string.IsNullOrWhiteSpace(input)) { return input; } var buffer = Convert.FromBase64String(input); using (RijndaelManaged rijndaelManaged = new RijndaelManaged()) { rijndaelManaged.Mode = CipherMode.CBC; rijndaelManaged.Padding = PaddingMode.PKCS7; rijndaelManaged.FeedbackSize = 128; rijndaelManaged.Key = Encoding.UTF8.GetBytes(key); rijndaelManaged.IV = Encoding.UTF8.GetBytes(iv); ICryptoTransform decryptor = rijndaelManaged.CreateDecryptor(rijndaelManaged.Key, rijndaelManaged.IV); using (MemoryStream msEncrypt = new MemoryStream(buffer)) { using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, decryptor, CryptoStreamMode.Read)) { using (StreamReader srEncrypt = new StreamReader(csEncrypt)) { return srEncrypt.ReadToEnd(); } } } } } static void Main(string[] args) { Console.WriteLine(EncryptByAES("137", "CJAVAPmXcuAksWmF", "V33CQ1428SI8ZNMT")); Console.WriteLine(DecryptByAES( "v9BxRJX+ojPDhyJFrglcbA==","CJAVAPmXcuAksWmF","V33CQ1428SI8ZNMT")); Console.ReadKey(); } }}
3､js的aes.js加解密实现代码
aes.js下载引用地址：https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/aes.js
//加密function encrypt(e,key,iv) { var r = CryptoJS.enc.Utf8.parse(key), var n = CryptoJS.enc.Utf8.parse(iv), var o = CryptoJS.enc.Utf8.parse(e), var u = { iv: n, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }, i = CryptoJS.AES.encrypt(o, r, u); return i.toString() }//解密function decrypt(str, key, iv) { var r = CryptoJS.enc.Utf8.parse(iv), var n = CryptoJS.enc.Utf8.parse(key), var o = CryptoJS.AES.decrypt(e, n, { iv: r, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); return CryptoJS.enc.Utf8.stringify(o).toString()}Node.js中实现AES(CBC)加密和解密：安装crypto：npm install crypto//加密function encrypt (data, key, iv) { iv = iv || ""; var clearEncoding = 'utf8'; var cipherEncoding = 'base64'; var cipherChunks = []; var cipher = crypto.createCipheriv('aes-128-cbc', key, iv); cipher.setAutoPadding(true); cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding)); cipherChunks.push(cipher.final(cipherEncoding)); return cipherChunks.join('');}//解密function decrypt (data, key, iv) { if (!data) { return ""; } iv = iv || ""; var clearEncoding = 'utf8'; var cipherEncoding = 'base64'; var cipherChunks = []; var decipher = crypto.createDecipheriv('aes-128-cbc', key, iv); decipher.setAutoPadding(true); cipherChunks.push(decipher.update(data, cipherEncoding, clearEncoding)); cipherChunks.push(decipher.final(clearEncoding)); return cipherChunks.join('');}
