I've used gpg4win's Kleopatra tool to create an OpenPGP RSA personal certificate. I want to export the private key for several reasons (import it on another machine, as well as backing it up in Keepass), so I right-clicked the certificate and chose "Export Secret Keys..." and chose to "ASCII armor" it.
If I open up the file in Notepad I see this kind of thing:
-----BEGIN PGP PRIVATE KEY BLOCK----- asdfhoewiqifEFJUIONsedfiOEJhioEFh8903FSED.....etc. etc. etc. etc. -----END PGP PRIVATE KEY BLOCK-----
How can I tell (or alternatively: know) if this is passphrase-protected?
