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.

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow.
