I have created a connected app that I want to use as part of a JWT flow.
For this I created a certificate, by using the Create CA-Signed Certificate button from Certificate and key Management in Salesforce Set up.
From some Salesforce documentation (https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_auth_key_and_cert.htm) salesforce dont mention to use this tool, but instead use openSSl instead. I can see how much more flexibility openssl gives but will be enough using the salesforce tool to have a jwt flow?
