Generate a strong secret from the shell

A good tool to generate strong passwords and secrets is "apg". You can get it with

sudo apt-get install apg

To create a strong secret for sessions, hashed Paperclip paths, etc. say

apg -m128 -a1 -E\'\"

Arguments explained:

  • The -m parameter defines the secret length
  • -a1 makes apg choose from all 7-bit ASCII characters instead of just the alphabet
  • -E\'\" excludes quote characters so you can easily paste the secret into a Ruby string

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
