There are mainly two folders, components and rollups
The first one is the component and the second one is the summary.
The files in the summary folder are compressed after the assembly of one or more folders.
This allows aggregation of separate folders into your project to incorporate project files without having to worry about its dependencies.

var md5 = CryptoJS.MD5("Message").toString(CryptoJS.enc.Hex);
console.log("md5 = %s", md5);
var sHA1 = CryptoJS.SHA1("Message").toString(CryptoJS.enc.Hex);
console.log("sHA1 = %s", sHA1);
var sHA256 = CryptoJS.SHA256("Message").toString(CryptoJS.enc.Hex);

var aesEncrypt = CryptoJS.AES.encrypt("Message", "Secret Passphrase");
console.log("aesEncrypt = %s", aesEncrypt.iv.toString(CryptoJS.enc.Hex));
var aesDecrypt = CryptoJS.AES.decrypt(aesEncrypt, "Secret Passphrase");
console.log("aesDecrypt = %s", aesDecrypt.toString(CryptoJS.enc.Utf8));
// base64 encrypt
var rawStr = "hello world!";
var wordArray = CryptoJS.enc.Utf8.parse(rawStr);
var base64 = CryptoJS.enc.Base64.stringify(wordArray);
console.log('base64Encrypt = ', base64);
// base64 decrypt
var parsedWordArray = CryptoJS.enc.Base64.parse(base64);
var parsedStr = parsedWordArray.toString(CryptoJS.enc.Utf8);
console.log('base64Decrypt = ',parsedStr);
</script>
</body>
</html>Since the background java uses AES encryption and uses AES/EBC/PKCS5Padding for initialization,
1、首先var key = CryptoJS.enc.Utf8.parse(key);
2、由于后端用的PKCS5Padding，而CryptoJS类库类库中没有，但有PKCS7Padding，跟PKCS5Padding是一样的，所以加密时加上红色部分的参数即可：CryptoJS.AES.encrypt(text, key, {
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.Pkcs7
