JavaScript与Java之间AES加密解密

采用CBC模式

JavaScript代码：

$(document).ready(function (){var str = "你好";var e = AESUtils.encrypt(str);var d = AESUtils.decrypt(e);console.log("明文："+str);console.log("加密："+e);console.log("解密："+d);});var AESUtils = {key:CryptoJS.enc.Utf8.parse("1234567891234567"),iv:CryptoJS.enc.Utf8.parse("1234567981234657"),/** * 加密  * 返回密文（base64）的16进制大写字符串 * @param {Object} data */encrypt:function(data){var srcs = CryptoJS.enc.Utf8.parse(data);var encrypted = CryptoJS.AES.encrypt(srcs, this.key, {iv:this.iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.Pkcs7});return encrypted.ciphertext.toString().toUpperCase();},/** * 解密 * @param {Object} data */decrypt:function(data){var encryptedHexStr = CryptoJS.enc.Hex.parse(data);  var encryptedBase64Str = CryptoJS.enc.Base64.stringify(encryptedHexStr); var decrypted = CryptoJS.AES.decrypt(encryptedBase64Str, this.key, {iv:this.iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.Pkcs7});return decrypted.toString(CryptoJS.enc.Utf8);}}
