Howto Fix OpenSSL::Cipher::CipherError on Ruby on Rails 7
I upgraded CMS of myrtana, oni_sorceress, to Rails 7 - generated a new application and moved files over there, but the deploy failed on:
tasks: TOP => deploy:assets:precompile
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as myrtana_sk@myrtana.sk: rake exit status: 1
rake stdout: Nothing written
rake stderr: rake aborted!

Tasks: TOP => environment
(See full trace by running task with --trace)
It sucks that openssl cipher object is hard to inspect, but I debugged MessageEncryptor instead. Didn’t really find out exactly what the hell is going on, but in the end I knew. I used old master.key file which not sure what ciper is exactly, but originates from Rails 4 or 5 era.
The solution? Remove credentials.yml and master.key, generated new ones (EDITOR=vim bin/rails credentials:edit), copy data over (or keep them if not really used other than for the session) and copy new master.key to the server (for Capistrano shared/config/master.key).
Now the deploy should work.
