[Feature Request]: Add hash calculations to calculation transform for various field types and algorithms

[vdwals]

What would you like to happen?

For some APIs I need to calculate hash values of certain strings for authentication. I utilized a external service called via REST API, but this had become a bottleneck and critical dependency quickly. Therefore I developed an own small plugin https://github.com/vdwals/hop-plugin-hashing based on the existing calculation transform.

During this process, I figured out, the current calculation transform could be enhanced to do certain hashing calculations with only a few changes, and therefore I would spent time more efficiently enhancing the calculation step than improving my plugin.

So sum up: Add further calculation to the calculation transform to calculate hash strings and binaries from certain inputs. Maybe even with a variable algorithm set by "Field B".

Extra calculations to the calculator are always welcome! Thanks for stepping up!
You can assign an issue to yourself by placing a .take-issue comment. (now i hope this won't trigger it and assign it to me)

Reading your use case, did you need something different than the "Add Checksum" Transform? I saw all the hash methods you used present there: [image: image.png]

@usbrandon You're absolutely correct, and I appreciate you bringing it to my attention. I hadn't taken that into consideration. Thank you for letting me know. While it's still possible to calculate more values in a single step using the calculation plugin, it does seem quite unusual.
