degrades, so developers without the secret key can still clone and commit to a

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 @code{gcrypt:} URLs that access a remote repository encrypted
with GPG, using our custom format.

Supported locations are local, @code{rsync://} and @code{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.")
