INTRODUCTION
|
|
|
|
Install as `git-remote-gcrypt` in $PATH
|
|
|
|
Supports local, ssh:// and sftp:// remotes at the moment,
|
|
as well as the special gitception://<giturl> remote type::
|
|
|
|
git config --global gcrypt.recipients KEYID1
|
|
git remote add gcryptrepo gcrypt::ssh://hostname.com:MyNewRepo
|
|
( or maybe:
|
|
git remote add gcryptrepo gcrypt::gitception://git@github.com/Secrets
|
|
)
|
|
git push --all gcryptrepo
|
|
|
|
CONFIGURATION
|
|
|
|
* Repository read access is set up from `git config gcrypt.recipients`
|
|
when creating new repositories.
|
|
|
|
* Set `git config gcrypt.signmanifest` to apply your signature to the
|
|
manifest when pushing.
|
|
* Set `git config gcrypt.requiresign` to always fail and stop if no
|
|
valid signature is found on the manifest.
|
|
|
|
* NOTE: We use the users gnupg configuration for cipher-algo and so on!
|
|
Configure your gnupg to use a strong crypto -- see `man gpg`.
|
|
|
|
|
|
REPOSITORY FORMAT
|
|
|
|
* masterkey is encrypted-to all gcrypt.recipients using `gpg -e`
|
|
* manifest contains the branches and the pack list
|
|
