How to compute the jws signature with SHA256withRSA

Hello, All.
I'm writing a simple implementation of Auth 2.0 for Server to Server Applications for my application using this text https://developers.google.com/identity/protocols/OAuth2Serv....

Unfortunatly, i have no expirience with cryptography, so i'm not sure how to implement this: "Sign the UTF-8 representation of the input using SHA256withRSA".

Can anyone show example code or pseudo-code for this task?
I have RSA key and input string - how to process them?

Thanks!

Gauche Scheme:

12.32 rfc.sha - SHA message digest
Module: rfc.sha

This module implements US Secure Hash Algorithm defined in RFC
4634. It provides SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512
(the latter four are sometimes referred as SHA-2
collectively).

The module extends util.digest (See section util.digest -
Message digester framework).

Thank you for reply!
In my case, i need to sign string using CL (sorry for missing this in first message).

I believe you thanked the WJ-bot in error. Trolls should not be fed :) Besides, as you noted, the Gauche (umpteen implementation of ) Scheme version is not CL :)

Hi Vitaliy,

I also have no experience with that, but take a look at the Ironclad
library; it probably provides what you need.

Hi Carlos,
it is impossible to do with ironclad, unfortunatelly.

As wrote to me Vadim Penzin (he is author of http://penzin.net...)

>>Ironclad does not support formatted RSA keys and signatures, that is those keys and signatures that must be represented in a certain (standard) way.
Ironclad is a wrong tool for the job that you described.
>>
>>I believe that you should use OpenSSLl's command line tools for that.

I tried to write code using openssl, but i still can't generate jwt that would be acceptable by googleapi.
