The simplest gem to encrypt and decrypt data, you only need to set a secret password to your credentials.

JustEncrypt works with Rails 5.2 onwards. Add the following line to your Gemfile:

gem 'just-encrypt'

Then run bundle install

Next, you need to add a secret key into your credentials file, the key must be 32 bytes. You can generate one easily with OpenSSL:

$ openssl rand -hex 32

Then edit your credentials:

$ EDITOR=vim rails credentials:edit

And add the secret key generated with the next structure:

just_encrypt:
  secret: YOUR_SECRET_KEY

require 'just-encrypt'

JustEncrypt.encrypt('STRING_TO_ENCRYPT')

require 'just-encrypt'

JustEncrypt.decrypt('STRING_TO_DECRYPT')
