PacCrypt

Important

PacCrypt is still in the beginning stages of development. PacCrypt has not been examined for vulnerabilities yet. Due to this, PacCrypt and PacShare are not recommended for PII or sensitive information. User discretion is advised.

PacCrypt is used for text encoding and decoding (using a basic Cypher), text and file encrypting and decrypting (using AES-GCM more algorithms coming) — built with Flask, JavaScript, and AES-GCM encryption.
Built in admin control panel, GitHub updater, and a Pac-Man like game! 🕹️

Note

Windows as a server host is not offically supported. Some features may not work, or work incorrectly, if hosted on Windows. It is recommended to host the server on Linux. PacCrypt Server has been tested on Debian and Arch. The official server is hosted using Debian.

Prerequisites

Python 3.7+
Flask 3+
Cryptography 42+
Waitress 2.1+
Git
Nginx (Recommended)

⚡ Quick Setup

git clone https://github.com/TySP-Dev/PacCrypt-Webapp.git
cd PacCrypt-Webapp
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Then run:

Development Mode:
```
./start_dev.sh
```
Production Mode:
```
./start_prod.sh
```

Visit http://127.0.0.1:5000 or http://localhost:5000 - If you are on the host system Visit http://hosts_private_ip - If you are not on the host system but on the same network Visit http://hosts_public_ip:5000 - If you are not on the host system but on a different network

🔑 Generate Passwords

Click Generate
