Git is a free distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

This package allows managing files with Git, without checking the file contents into Git. It can store files in many places, such as local hard drives and cloud storage services. It can also be used to keep a folder in sync between computers.

git-crypt enables transparent encryption and decryption of files in a git repository. Files which you choose to protect are encrypted when committed, and decrypted when checked out. git-crypt lets you freely share a repository containing a mix of public and private content. git-crypt gracefully degrades, so developers without the secret key can still clone and commit to a repository with encrypted files. This lets you store your secret material (such as keys or passwords) in the same repository as your code, without requiring you to lock down your entire repository.

git-remote-gcrypt is a Git remote helper to push and pull from repositories encrypted with GnuPG. It works with the standard Git transports, including repository hosting services like GitLab.

Remote helper programs are invoked by Git to handle network transport. This helper handles gcrypt: URLs that access a remote repository encrypted with GPG, using our custom format.

Supported locations are local, rsync:// and sftp://, where the repository is stored as a set of files, or instead any Git URL where gcrypt will store the same representation in a Git repository, bridged over arbitrary Git transport.

The aim is to provide confidential, authenticated Git storage and collaboration using typical untrusted file hosts or services.
