Are secrets hidden from admins too - ?

[lejeczek <peljasz@xxxxxxxxxxx>]

Hi guys.

On a remote & "shared" systems - are private secrets 
completely 100% safe? Can root get to those?
(naturally excluding hacking of unknown bugs & exploits and 
theories such as "no computer system is ultimately safe")

And if answer is yes then - do you have any best practices 
for storing & managing of those secrets?

many thanks, L.
