Is your feature request related to a problem? Please describe.
I would like to extract the header which contains the base64 value and decoded and return it in the body as a response.

Describe the solution you'd like
It has been requested before to have a base64 encoding feature here. It will be great if we can have the decoding feature as well.

Describe alternatives you've considered
I have to copy the value from the header response and use online converter tools to decode the string.
