Function for RSA SHA-256 digital signature

sect55Apr 6 2021

I am attempting to write an Oracle function to authenticate against DocuSign using JWT. It requires RSA SHA-256 digital signature as outlined below:
The signature part of the JWT is a digital signature that enables DocuSign to verify that the JWT was created by your application and has not been modified since it was created. The first two parts of the JWT are signed with your application's private key (using the RSA SHA-256 digital signature algorithm) as shown in the diagram.
When Oracle function should I be using?
I'm using Oracle 19c (EE).

group by status

Hi,
SUM (CASE ...), as Bede showed, will work. You could also use COUNT (CASE ...), like this:

SELECT    status              -- or  LOWER (status) AS status
,         COUNT (*)  AS col1  -- or a more descriptive name, like number_total
,	  COUNT ( CASE
	  	      WHEN  review_status = 'Y'
		      THEN  'OK'
	  	  END
	  	)    AS number_reviewed
FROM      temp1
GROUP BY  status
ORDER BY  status  -- or whatever
;

If you really want to display 'open' and 'close' even though the table has 'Open' and 'Close', as you said, then you just need to change the first line.
In any event, you don't need "SELECT DISTINCT". The GROUP BY clause guarantees that status will be distinct in the output
