REST API's, JSON Web Tokens & Hash Algorithms

[Bleiler, Timothy]

Thank you Tom!

This is all new to me and I’d missed that distinction. I hope you don’t mind a follow up question.

Is it your understanding that using SHA-256 or SHA3-256 as the “digestType” in the Livecode function would meet the service requirement for RS-256 or is there something else I’m missing?

Hey Tim, the ciphernames lists "encryption" algorithms not hashing.

I believe RS256 refers to RSA with SHA 256.

messagedigest is the function you want to look up for hashing algorithms.

Hi,

I’ve seen some great presentations in the last few years from the
conferences and Livecode Global sessions using Livecode to access REST
API’s from web services, so I’m hoping someone can help me out here.

I need to access a web service (Box.com<http://box.com/><http://Box.com<http://box.com/>>) from my Livecode
app using JSON web tokens.
The service  documentation states that they only support RS256, RS384, and
RS512 for hashing the signature in the token. Unfortunately, in the 139
options and variations listed by the Livecode CipherNames function I don’t
see these.

Have I missed or misunderstood something or am I out of luck for using
Livecode for this task?

Thanks,
