It would be very helpful if I could add actual .PEM key files into an actual Enpass secret. For example (RSA) Private Keys which are generated for various purposes like certificate generation or encryption.
The workaround at the moment is to copy and paste the data into a new multiline (sensitive) field and save it. Notes doesn't allow the sensitive data to be hidden from view, nor are multiple notes possible.
Ideally, I would just attach the PEM file into the secret and move on. This would shorten the time needed to copy the text from the secret, open a text editor, paste, save, then use it.
