GNUpgp?GNUpg?GPG?

I'm very confuse with the difference of GNUpgp, GNUpg and GPG~!?!?!?! :confused:

Wiki just showing GNUpg but not GNUpgp or GPG~~ are they the same or different?

Google even suggestion my string to be 'GNUPG', when i tried to search the word of 'GNUPGP'~~

I'm looking for info regard to GNUpgp~ does it exist? does it just mean of GNU liciense of PGP~?
Anything related to pgpi?

Sorry by asking those stupid question~~ hope some1 could help me to differenciate and provide more info regarding on GNUpgp~

Many thanks~

Good day~

There is no such thing as GNUpgp..

There is however the GNU Privacy Guard (GNUPG or GPG): http://www.gnupg.org/

Which is in fact a free replacemenet for PGP (Pretty Good Privacy)..
PGPi is the international homepage for pgp, which has something to do with weird crypto export rules in the USA..

Hope that helps..
