git-crypt provides transparent encryption and decryption of selected files inside Git repositories. It is designed for projects where most content can be shared normally, but certain files contain information that should only be accessible to authorised collaborators.
The software uses Git filters to encrypt protected files when they are committed and decrypt them in an authorised working copy. Once configured, users can continue performing ordinary Git operations without manually encrypting and decrypting files.
git-crypt is not intended to encrypt an entire repository. Filenames, commit messages and other metadata remain visible, and previously authorised users cannot be prevented from accessing historical content for which they already hold the necessary keys.
This is free and open source software.
Key Features
- Transparent encryption and decryption of selected files using Git filters.
- Specify encrypted paths and filename patterns through .gitattributes.
- AES-256 encryption using a synthetic initialisation vector derived from an HMAC.
- Support for sharing encrypted content with collaborators through GnuPG keys.
- Alternative symmetric-key mode without requiring GnuPG.
- Export repository encryption keys for secure transfer to authorised users.
- Unlock encrypted content in authorised working copies.
- Allow users without keys to clone repositories containing encrypted files.
- Multiple encryption keys within a repository for different groups of files or users.
- Inspect which files are encrypted or unencrypted using git-crypt status.
- Detect files that should have been encrypted but were added without protection.
- Deterministic encryption so Git can recognise unchanged protected content.
- Preserve ordinary Git workflows for unencrypted files in the same repository.
- Integrate with Git-based development workflows without requiring a separate encryption server.
