Google app script

[Deye]

hi,

I am trying to create a google app script that will encrypt a string with a password-key that will play along the _AesEncrypt() function from ward's AES.udf
 especially so the "web based _AesEncrypt()" will work when used with _AesDecrypt() of course ..
 
so far I've looked here :

https://ctrlq.org/code/19511-encryption-google-apps-script
https://github.com/digitalbazaar/forge/issues/134
 
Tried a few things ,but now I haven't got much clues on what else I should try 

TIA for any help pointers ,examples or any other ideas ..
