Git-crypt Setup Guide for Secure Repositories

For developers using git with sensitive data who need better security than just a private repository. Here's a guide to transparent git encryption with git-crypt that ensures data-at-rest and data-in-transit encryption. Perfect for use with note taking apps like Obsidian and Logseq.

Key Benefits

• Transparent encryption: Files are automatically encrypted when pushed, decrypted when pulled
• Selective encryption: Choose which files or directories to encrypt
• Cloud-provider agnostic: Works with any git host (GitHub, GitLab, Bitbucket, etc.)
• Perfect for note-taking apps: Seamlessly encrypt Obsidian vaults, Logseq graphs, or any markdown-based notes
