RuntimeError: Digest::Base cannot be directly inherited in Ruby

[mcoetzee]

Alright so we are sporadically getting this RuntimeError in our Sidekiq workers and the offending line of code is lib/sekrets.rb#L303:

cipher.key = Digest::SHA256.digest(key.to_s).slice(0,16)

After some digging I found a similar issue in the aerospike-client-ruby gem:
Digest::Base cannot be directly inherited in Ruby

Which they solved by using the thread-safe digest lookup.

Would you agree that this line lib/sekrets.rb#L303 should similarly be changed to use the thread-safe digest lookup?
