Store secrets encoded or decoded in exam?

Kubernetes
#1

Hello!

I watched the video: https://www.youtube.com/watch?v=9UqkWcdy140&t=61s or Kubernetes Certification Exam Environment Preview.
For me is not clear how the secrets’ values should be stored during the exam, encoded or decoded? Here, I see a mix.

Thank you,
Adrian

Thanks for response.
I expect base64 for password also.
I would expect:

λ k get secrets credentials -oyaml | yq '.data.password' | base64 -d  > pass.txt
λ k get secrets credentials -oyaml | yq '.data.username' | base64 -d > user.txt.cpt

then 

λ ccrypt -d user.txt.cpt -k pass.txt

Am I missing something?
