gitcrypt

Gitcrypt is a set of scripts used to encrypt and decrypt automatically for you git repositories.

Installation

Put fnmatch, git_crypt_filter in one of your $PATH directories.

Usage

1. Create a new git repository.

    $> git init encryped_repo
    $> cd encryped_repo
   

Then run git_crypt_deploy, and it will guide you to configurate the encryption and decryption settings.

    $> ~/bin/git_crypt_deploy

2. Edit the pattern list file, default is .gitcrypt, it works like .gitignore. Each line is a pattern to match file names. All matched files will be encrypted before staging(store as git blob files). And they are decrypted when checking out automatically. The fnmatch script is used to match a file name with a file containing glob patterns, there's an example of how to use it:

    # Lines begin with # are comments
    # Encrypt all indexed files
    *
    # Encrypt files under `passwords` directory
    passwords/\
    # Just encrypt file `ssh/config`
    ssh/config
   

3. Commit changes

    $> git commit passwords/ -m "Add password for Facebook"
   

Then all changes are encrypted and stored as git blobs. If you push the changes to a public remote repository, others will only see the encrypted version as long as you don't share the salt and key with them.
