To tell the truth, GitHub is not entirely safe for private notes. Imagine a 15-year-old hacker discovering a vulnerability that could expose a private repository. If someone has malicious intent toward you, they could exploit this bug and make your private data public.
-
What our script does: It is a simple script that utilizes the 7z API to encrypt notes using SHA-256. It creates a password-protected zip file with a specified size limit (in MB you provide during running the script) and then pushes these encrypted backups to GitHub.
Key Features
- Military-grade AES-256 encryption via 7z (FIPS 197 compliant)
- Configurable chunk sizing for optimized storage
- Automated GitHub synchronization workflow
- Salted SHA-256 hashing for file integrity verification
- Download & Install the code.
git clone https://github.com/Ctmax-ui/obsidian-data-packer.git
cd obsidian-data-packer
pip install -r requirements.txt- Paste your notes folder or the folder you want to ecnrypt in this repo root.
- Run the main.py
- Make an output folder & link that to your github private repo.
mkdir output && cd output
git init
git remote add origin <your repo url>- Run the main.py or double click on the run.bat In windows.
Security Considerations Table
| Feature | Standard GitHub | Obsidian Data Packer |
|---|---|---|
| At-rest encryption | ❌ No | ✅ AES-256 |
| Chunked storage | ❌ Single file risk | ✅ Split archives |
| Local key management | ❌ Relies on GH | ✅ Client-side control |
| Metadata protection | ❌ Visible structure | ✅ Obfuscated contents |
