I need to access my secret GPG/PGP key to copy/paste it into another application.
How do I show my secret key without generating too much traces of it?
I only know of the export command to gpg (or the export function in several GUI-GPG tools), but this would always generate a file. A file on the filesystem needs to be securely erased afterwards, may get picked up by synchronization, backup or mirroring tools etc.
So is there a way to show it in a dialog window (no traces except RAM/swapfile) or at least only to the console window (will leave trace in console history)?
