这里的密钥是由

 //十六位十六进制数作为密钥偏移量

const CryptoJS = require('crypto-js'); //引用AES源码js const key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF"); //十六位十六进制数作为密钥 const iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412'); //十六位十六进制数作为密钥偏移量 //解密方法 function Decrypt(word) { let encryptedHexStr = CryptoJS.enc.Hex.parse(word); let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr); let decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8); return decryptedStr.toString(); } //加密方法 function Encrypt(word) { let srcs = CryptoJS.enc.Utf8.parse(word); let encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 }); return encrypted.ciphertext.toString().toUpperCase(); } export default { Decrypt , Encrypt }
