There are scads of options presented by GnuPG, which are all part of making it the flexible and powerful an encryption framework that it is. But it's extremely complicated to get started with, and that quite reasonably puts people off.
egpg is a wrapper script that tries to simplify the process of using GnuPG. In order to simplify things, it is opinionated about the "right" way to use GnuPG.
The philosophic goals here are these:
Make GPG as easy to use as possible. The more people using strong encryption, the better for everyone. One of the big hang ups right now is that the GPG tools are difficult to use - moreso than they strictly have to be.
Make the interface itself auditable. This is why this is presented as shell scripts rather than a web service or a GUI. If you're concerned about what egpg does, open up the files and read them, or have someone you trust read them.
Build a guide forward. The simplified interface provided here should be good to get started with, and with luck many users will find they never need anything beyond what egpg provides. If you find that you need to do something more, though, the goal is that you have a foundation to start with, and some direction on how to proceed.

- https://fosdem.org/2018/schedule/event/easy_gnupg/ (lightning talk)
git clone --branch gnupg-2.1 https://github.com/easygnupg/egpg cd egpg/ sudo make install
Debian and Ubuntu:
apt install gnupg2 pinentry-tty haveged libgfshare-bin parcimonie \ qrencode imagemagick zbar-tools wget realpath psmisc
For development, you need also
ronnto make the man pages:
apt install ruby-dev gcc gem install ronn
egpg presents a series of subcommands:
egpg init egpg key gen [<email> <name>] egpg key ls egpg contact search <name> egpg contact ls egpg sign <file> egpg verify <file.signature> egpg seal <file> [<recipient>+] egpg open <file.sealed> egpg help egpg key help egpg contact help egpg ext help
These should be the minimal set required to use GPG effectively.
Any suggestions or discussions about supported operations, simplified terminology, etc. is wellcome.
