Gpgcrypt

This gem is designed to allow you to manually encrypt/ decrypt RSA encoded messages using GnuPG.

Installation

Install the gem:

$ gem install gpgcrypt

Usage Template

Encrypting:

$ gpgcrypt message public_key

Decrypting:

$ gpgcrypt encrypted_message private_key

Usage

Have your partner generate a public/private key pair (You may have already done this). 

$ ssh-keygen -t rsa

Obtain a copy of your partner's public key.

And then use gpgcrypt to encrypt a message using your partner's public key:

$ gpgcrypt message.txt public_key_of_recipient_rsa.pub > encrypted_message.txt

Or have your partner decrypt a message of yours using your own private key:

$ gpgcrypt encrypted_message.txt your_private_key_rsa > message.txt

Alternate Usage

You can alternatively specify a URL to public keys or messages

Encrypting:

$ gpgcrypt message.txt github.com/TheNotary/pgp/raw
Your message has been pastebin'd to http://pastebin.com/lkajds;lkfjsdaf

Decrypting:

$ gpgcrypt http://pastebin.com/lkajds;lkfjsdaf ~/.ssh/id_rsa

Later, you will be able to add other people's public keys to your ~/.gpgc folder. Then you will be able to set their key as the default key. 

$ gpgc --save-key pastebin.com/raw/;laksjdflkjdf joe
$ gpgc --converse-with ~/.gpgc/joe
$ gpgc "Hey, let me know when you've made the finishing touches."
