EasyPGPeasy

This is a simple and easy (hopefully) to use PGP tool.

Features

[X] Create new PGP Keypairs, able to choose between 4096, 8192 and 16384 (overkill perhaps) bit keys.

[X] Paste from clipboard.

[X] Import messages, PGP Public Keys and PGP Signatures.

[X] Encrypt, Decrypt, Sign and Verify files and messages.

[X] Switch language.

[X] Small help window.

TODO

Release to a standalone executable.

What the tool can do

Create new PGP Keypairs, they'll be automatically saved in two separate files appropriately named in ./Keys, which will be used when Encrypting, Decrypting, Signing and Verifying signature files and messages. Please note, every time you create new Keypairs, the old ones will be overwritten. If you want to use your own Keypairs, create a new pair to check if the formatting and replace the content of the created ones with your own.

Imported Public PGP Keys, messages (in order to sign or verify them) and signatures (that correspond to the imported message) will be saved in ./Imported, and also rewritten with every import. The imported public keys will be used in encrypting and verifying. Please note imported Private PGP keys will be saved in ./Imported.

Encrypting, decrypting, signing and verifying files and messages using the created keys and imported keys where necessary.

Language change (only English and Spanish, I know no other languages).

A TL;DR short help window.

How to use the tool

If you want to create a PGP Keypair, select the bit size to use, choose whether you want a random or your own name, surname and email, type a passphrase for your PGP Private Key and create it. It will automatically create a Keypair with the chosen name, surname and email. Created Keypairs will be overwritten on every button press and will be automatically saved in ./Keys folder. Any operation that needs to use the PGP Private Key will ask for the passphrase.

You can import a message that was encrypted with your public key to automatically decrypt it, if the encrypted message was signed and you import the signature you can verify it, import a plaintext message and it's signature to verify it. You can import a PGP Public Key to encrypt a message. All of the above also applies with files and everything imported will be in the folder ./Imported.

If you want to encrypt a file/message, you first need to import the PGP Public Key, then type or paste the message, click encrypt and in the output the encrypted message will show and save in ./Output/Encrypted folder.

If you want to decrypt a file/message someone encrypted with your PGP Public Key, first, paste the encrypted message, press decrypt, type the passphrase and voilà, if the encrypted message was imported, you can autodecrypt, you can also choose to decrypt a file you encrypted. Decrypted files amd messages will be saved in ./Output/Decrypted.

If you want to sign a file/message, you can type a plaintext message, and press sign, you can automatically sign a message that was imported, be it plaintext or encrypted, or a file and will be saved in ./Output/Signed. The signing operation requires you to type the PGP Private Key passphrase.

If you want to verify a file/message, you need import the message, import the PGP Public Key, import the signature along with the corresponding PGP Public Key to verify that message, if will give a positive or negative result and save the verified message in ./Output/Verified, it will not save anything when verifying a file.

If anything goes wrong, an error will pop up and redirect you to the menu. If the tool crashes please open a ticket, with clear instructions on your steps to encounter the issue and I'll try and replicate the issue on my end and fix it the best I can.

Requirements

You'll need xclip for the copy/paste to/from clipboard actions to work.

Ubuntu

apt install python3-tk xclip

Fedora

dnf install python3-tk xclip

Python dependecies

Python 3.6+
PySimpleGUI
pgpy
png
pyclip
pyqrcode

Install with: python -m pip install PySimpleGUI pgpy pypng pyclip pyqrcode

Tails

If you wish to use it with TAILS, for whatever reason, follow the next steps to use it (not recommended).

sudo torify apt-get update

sudo torify apt-get install python3-pip gcc zlib1g-dev python3-tk

torify python3 -m pip install setuptools wheel

torify python3 -m pip install pyinstaller pyclip pypng pgpy pyqrcode PySimpleGUI tk

python3 EasyPGPeasy.py

What I do recommend is creating the release, copying it to a USB, rebooting TAILS so it's back to default TAILS and then executing the release from the home directory (if you have created Keypairs I suggest you have them on the USB to use them).

python3 /home/amnesia/.local/bin/pyinstaller -F EasyPGPeasy.py

./EasyPGPeasy

The release will be in the dist folder, make it executable and you're golden.

Usage

Execute python EasyPGPeasy.py (or python3 EasyPGPeasy.py depends on your system) and navigate through the menus, or execute one of the releases.

Releases

Tried on Fedora 33, 34 and 35, TAILS 4.29, several windows 10 builds (currently trying to build for Mac and try it).

Credits

Thanks to the guys who wrote the following Python libraries/modules, couldn't have done it without their awesome code:

Thanks to https://www.reddit.com/user/chaosharmonic/ for suggesting the name chang. I quite like it!

Coffee

Last but not least, if you found the tool useful and would like to help me out and buy me a coffee, I've included the addresses in the tool that'll be copied to clipboard automatically whilst a 5 second popup shows a QR code you can scan.

Sidenote

UNIX users should have no issue, though I've only been able to test on Fedora, will continue testing.

Mac users, it should work like with UNIX users.

Windows users, only PDF and txt files work when encrypting and decrypting, other file formats aren't recoverable as far as I've tested.
