首先下载 aes.js加密工具类：
本文采用的是 AES/ECB/PKCS5Padding的加密方式进行加密的：
js加密写法如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <script src="aes.js"></script> <body> <script> var key = CryptoJS.enc.Utf8.parse("8NONwyJtHesysWpM"); var plaintText = 'ABCDEFGH'; // 明文 var encryptedData = CryptoJS.AES.encrypt(plaintText, key, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); console.log("加密前："+plaintText); console.log("加密后："+encryptedData); encryptedData = encryptedData.ciphertext.toString(); var encryptedHexStr = CryptoJS.enc.Hex.parse(encryptedData); var encryptedBase64Str = CryptoJS.enc.Base64.stringify(encryptedHexStr); var decryptedData = CryptoJS.AES.decrypt(encryptedBase64Str, key, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); var decryptedStr = decryptedData.toString(CryptoJS.enc.Utf8); console.log("解密后:"+decryptedStr); var pwd = "PCsUFtgog9/qpqmqXsuCRQ=="; //加密服务端返回的数据 var decryptedData = CryptoJS.AES.decrypt(pwd, key, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); console.log("解密服务端返回的数据:"+decryptedStr); </script> </body> </html>
Java加解密类：
import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; import org.apache.commons.net.util.Base64; public class AESUtil { public static String encrypt(String input, String key){ byte[] crypted = null; try{ SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"); cipher.init(Cipher.ENCRYPT_MODE, skey); crypted = cipher.doFinal(input.getBytes()); }catch(Exception e){ System.out.println(e.toString()); } return new String(Base64.encodeBase64(crypted)); } public static String decrypt(String input, String key){ byte[] output = null; try{ SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding"); cipher.init(Cipher.DECRYPT_MODE, skey); output = cipher.doFinal(Base64.decodeBase64(input)); }catch(Exception e){ System.out.println(e.toString()); } return new String(output); } public static void main(String[] args) { String key = "8NONwyJtHesysWpM"; String data = "ABCDEFGH"; System.out.println(AESUtil.decrypt(AESUtil.encrypt(data, key), key)); System.out.println(AESUtil.encrypt(data, key)); } }
