Is it possible to use HS256 symmetric encryption algorithm for generation of JWTs? I can only see the asymmetric encryption RS256 used in the walkthroughs. 

I am trying to consume https://account-d.docusign.com/oauth/token with a JWT to get an access token, but it would be easier if this was possible with HS256 JWT encryption.

Hello Emiliy1008,
 
Thank you for using Docusign Community Support. 

At this time, our authentication system only uses RS256 to process token request. 

We have SDKs in several programming languages that already have the coding to use RS256, we hope one of them may safe you some time:

​@Emily1008 You can use JWT Util to generate JWT Assertion if your development language is java. Please reference this code:
