Informations about the package git-deploy-key
Deploy key generator
This CLI application simplifies the process of generating deploy keys for git repositories.
Background
Git allows users to authenticate using SSH public keys. While this is superior to password authentication, most users typically only use a single SSH key in their environment.
The ideal situation is to use a unique key for each repository and deployment, with entirely different keys being used to log into machines.
How it works
This application generates an ECDSA key suitable for SSH. After creation, the key must be granted access on the remote git server. Github has a repository settings for this - users of Github will be directed to this page.
Keys are saved in the folder ~/.ssh/gitdeploy
. Each repository gets
it's own entry in ~/.ssh/config
, specifying a name for the host, the
user/domain/port, and the key file.
Keys are encrypted using the default SSH procedure (salted password, key derived through single pass of md5). PKCS#8 encoding is on the wishlist, as it enables stretching of encryption key material.
The tool supports unencrypted keys by setting the --no-password option.
Usage
Install the tool:
This tool is available through composer. The following command will save the application to the global composer directory (~/.composer)
composer global require afk11/git-deploy-key
Update your $PATH to include ~/.composer/vendor/bin:
echo "export PATH=~/.composer/vendor/bin:\$PATH" >> ~/.bashrc
source ~/.bashrc # this is done automatically when you log in
At this point you can use the tool anywhere:
git-deploy-key help
You can also checkout this repository and access the executable in bin/
directory after running composer install

Custom names for sessions
The default name for each session is made from the domain, organization, and repository. Custom names can be given by providing a second argument.
$ git-deploy-key create [email protected]:Bit-Wasp/bitcoin-php gitbitcoin
$ git clone gitbitcoin:Bit-Wasp/bitcoin-php
Unprotected SSH key:
The --no-password
option can be set to disable encryption of the key.
This can be useful during automated deployments with scheduled updates.
user@dev:~$ git-deploy-key create [email protected]:Bit-Wasp/bitcoin-p2p-php --no-password
