How To Decrypt AES 256 bit encrypted text in ServiceNow server side ?

[Rahul_Dhir0047]

I have a use case where I am connecting DarwinBox to ServiceNow. The API is returning an AES 256 encrypted text. The encryption logic used is CBC. Is there any script which works reliably on server side to decrypt this ? 

i have tried GlideCryptoModule and tried using CryptoJS in servicenow via CDN. But the former doesnt work. and the later is not an updated library which i found. 

Would appreciate if someone can guide me on how to implement this on ServiceNow.

I don't think anything available OOTB for this
