Transparent

chezmoi supports encrypting files with transparent git encryption tools like transcrypt and git-crypt.

transcrypt

In your configuration file, set encryption to transparent:

encryption = "transparent"

Initialize transcrypt:

$ chezmoi cd
$ transcrypt

Edit .gitattributes to use transcrypt for files with the encrypted_ prefix:

encrypted_* filter=crypt diff=crypt merge=crypt

Add an encrypted file to both chezmoi and git:

$ chezmoi add ~/.config/sensitive_file
$ git add dot_config/encrypted_sensitive_file
$ git commit -m "Add .config/sensitive_file"

Verify that the file is handled by transcrypt:

$ git ls-crypt
dot_config/encrypted_sensitive_file

Note that commands like git show, git diff, etc. will also show the cleartext form of the file.

Use transcrypt --display to show instructions for how to setup transcrypt after cloning the repository elsewhere. It will involve running a command like:

$ transcrypt -c aes-256-cbc -p $PASSWORD
