credentials.yml.enc and master.key

Mechanism for managing confidential information of apps that appeared in Rails 5.2

master.key A file containing the private key for decrypting the encrypted secret information written in credentials.yml.enc

credentials.yml.enc An encrypted file of credentials.yml

credentials.yml File with confidential information

how to use

When editing confidential information

Instead of editing credentials.yml.enc directly, edit it with the following command

EDITOR='vim' rails credentials:edit

Why not edit credentials.yml.enc directly?

Because credentials.yml.enc is an encrypted file and you can't edit it. (.enc means encrypted file)

When calling confidential information

After launching Rails console, type the following command

Rails.application.credentials[:Confidential information you want to get]
