Using atob/btoa server side, and GlideRhinoHelper?

xiaix · ‎11-23-2020

So, I'm trying to Base64 decode a Base64 encoded string within a Script Include (server side). Of course I get "atob is not defined", so I'm wondering how to do this in ServiceNow.

I'm thinking I can use ServiceNow's "GlideRhinoHelper", but there is 0 documentation for it!

Anyone able to assist?

Ok, finally got it.

JSON.parse(GlideStringUtil.base64Decode(s))

So for example this Base64 encoded string:
eyJndWlkIjoiMjhmZDdiYmQtM2U2Ny00MDMwLTlhN2YtN2YzMzk1Zjc3Nzg2IiwiYWN0aW9uIjoidXBkYXRlIiwiZmllbGRzIjoiZW1haWwsbGFzdF9uYW1lIn0=

Nevermind... found it.

GlideStringUtil.base64Decode()

GlideStringUtil.base64Encode()

Well, this sucks... seems you can only use GlideStringUtil.base64Decode() on something that was encoded with GlideBase64.encode()

And it there is no such thing as GlideBase64.decode()

So if something was encoded with btoa('test'), GlideStringUtil.base64Decode() won't work.

So frustrating!

Hi xiaix,

Did you have to do anything to else after "GlideStringUtil.base64Decode() on something that was encoded with GlideBase64.encode()" to make GlideStringUtil.base64Decode() work? I'm trying to convert a base64 string (generated using CertificateEncryption.generateMac() ) into hex and GlideStringUtil.base64Decode() doesn't work.
