nib-crypt

Add basic file encryption/decryption support to nib. This project deviates from the original intention of nib in that it does not specifically relate to docker-compose at all. In that way the API will be slightly different because a "service" is not involved, just file en/decryption.

Install the gem on your machine globally:

gem install nib-crypt

• OpenSSL is used to perform the file encryption/decryption (present on most systems already)
• AWS Command Line Interface is used to fetch and persist keys on in a bucket on S3 (install via whalebrew recommended)

nib-crypt will use a shared key for the purposes of encryption and decryption. These keys are to be stored in a (hopefully!) secure bucket on AWS S3. That means nib-crypt must be configured with the name of the bucket you would like to store secret files in.

# .bashrc or .zshenv etc
export NIB_CRYPT_BUCKET_NAME=secrets-r-us

nib-crypt expects a file name secrets.aes to be present in the current directory (typically the root of a project). If this file does not exists the crypt-init command can be used to create one or pull an existing one from AWS S3 if one exists for the project.

This command will check to see if a key exists for the current project (stored as projectname.secrets.aes on AWS S3). If a key exists it will be copied down from AWS S3. If a key does not yet exist a new one will be created and pushed to the configured bucket on AWS S3.

nib crypt-init

Use the existing key file to encrypt a file

nib encrypt [input] [output]

nib decrypt [input] [output]

After pull down the repo build an image and use Guard to facilitate running specs and RuboCop.

nib build
nib guard gem
