Correct. 

And for added knowledge:
 - LibreOffice can do some operations using OpenPGP. And other operations using
x509
 - Kleopatra works with both OpenPGP keys and x509 certificates for different
and similar things
 - KMail cans sign and verify both with OpenPGP and with x509 (S/Mime)
 - GnuPG has tools to work with OpenPGP keys (gpg) and with x509 certificates
(gpgsm)
