此加密及解密是用AES方式需要引入 aes.js、core-min.js檔案
自訂 common.js
/** * * @param encryptchar 加密字元 * @param key 加密私密金鑰 * @return */function encrypt(encryptchar,key){if(encryptchar==""||key==""){alert("加密字元或私密金鑰為空白!");return;}var array=new Array();array[0]=key;array[1]=CryptoJS.AES.encrypt(encryptchar,key);;return array;}/** * * @param char 密文 * @param key 解密私密金鑰 * @return */function decrypt(char,key){if(char==""||key==""){alert("密文或私密金鑰為空白!");return;}return CryptoJS.AES.decrypt(char,key).toString(CryptoJS.enc.Utf8);}
