[git-remote-gcrypt](https://github.com/blake2-ppc/git-remote-gcrypt/)
adds support for encrypted remotes to git. The git-annex gcrypt special
remote allows git-annex to also store its files in such repositories.
Naturally, git-annex encrypts the files it stores too, so everything
stored on the remote is encrypted.

## configuration

These parameters can be passed to `git annex initremote` to configure
gcrypt:

* `encryption` - One of "none", "hybrid", "shared", or "pubkey".
  See [[encryption]].

* `keyid` - Specifies the gpg key to use for encryption of both the files
  git-annex stores in the repository, as well as to encrypt the git
  repository itself. May be repeated when multiple participants
  should have access to the repository.

* `gitrepo` - Required. The path or url to the git repository
  for gcrypt to use. This repository should be either empty, or an existing
  gcrypt repositry.

## notes

For git-annex to store files in a repository on a remote server, you need
shell access, and `rsync` must be installed. 

While you can use git-remote-gcrypt with servers like github, git-annex
can't store files on them. In such a case, you can just use
git-remote-gcrypt directly.

If you use encryption=hybrid, you can add more gpg keys that can access
the files git-annex stored in the gcrypt repository. However, due to the
way git-remote-gcrypt encrypts the git repository, you will need to somehow
force it to re-push everything again, so that the encrypted repository can
be decrypted by the added keys.
