Yes, I understand how to do that. If you read my question carefully,
you will realize I am trying to get it in STRING format! Something
that could be added to another application like GnuPG. I have a
PgpPublicKey object -> STRING format. I'm not sure why there are no
examples in string format because without that, it really can not be
used in another application.
