sample code:<\/p>\n
var CryptoJS = require("crypto-js"); \nlet secretKey = 'yourSecretKey'; \n\nfunction decrypt(aesStr, key) { \n return CryptoJS.AES.decrypt( \n aesStr, \n CryptoJS.enc.Utf8.parse(padding(key)), \n { \n mode: CryptoJS.mode.ECB, \n padding: CryptoJS.pad.Pkcs7 \n } \n ).toString(CryptoJS.enc.Utf8) \n} \n\nfunction padding(key) { \n return key.padEnd(32, '\\0'); \n} \n\n\/\/decrypt("encryptedData", secretKey)<\/pre>\nHere we choose AES-256 to encrypt \/ decrypt the secure information. When using AES, the length of the secretKey is important. The length of secretKey in AES-128 is 16 bits, and in AES-256 is 32 bits.<\/p>\n
And in our case, the length of secretKey is no enough. So we will use the function padding to fill in the missing length.<\/p>\n
