Any Encryption tool in Gnome?

Hi Friends

Please help, any encryption tool is there in gnome? In my system I can’t able to install KDE, so no KGPG.

I have gone through the man pages of gpg2. but not understand properly.

How to encrypt certain file with certain keys using gpg2?

I haven’t used it, but u can check “Seahorse” out here:
