krypt

A command line file encrypter and decrypter.

This program started as a clone of ansible-vault. Support for additional ciphers and a different binary only file format was added for flexibility.

Installing

Compile

This project has only been tested with go1.14+. To compile just run go get -u github.com/gesquive/krypt and the executable should be built for you automatically in your $GOPATH. This project uses go mods, so you might need to set GO111MODULE=on in order for go get to complete properly.

Optionally you can run make install to build and copy the executable to /usr/local/bin/ with correct permissions.

Download

Alternately, you can download the latest release for your platform from github.

Once you have an executable, make sure to copy it somewhere on your path like /usr/local/bin or C:/Program Files/. If on a *nix/mac system, make sure to run chmod +x /path/to/krypt.

Homebrew

This app is also avalable from this homebrew tap. Just install the tap and then the app will be available.

$ brew tap gesquive/tap
$ brew install krypt

Configuration

Precedence Order

The application looks for variables in the following order:

• command line flag
• environment variable
• config file variable
• default

So any variable specified on the command line would override values set in the environment or config file.

Config File

The application looks for a configuration file at the following locations in order:

• ./config.yml
• ~/.config/krypt/config.yml
• /etc/krypt/config.yml

Environment Variables

Optionally, instead of using a config file you can specify config entries as environment variables. Use the prefix "KRYPT_" in front of the uppercased variable name. For example, the config variable password-file would be the environment variable KRYPT_PASSWORD_FILE.
