Kerckhoffs law states that a cryptosystem should be secure even if
everything about the system is public knowledge. This is also konwn as
Shannons maxim where it is formulated as "the enemy knows the system".

This is a very important part in all cryptosystems and secure systems
and applies very well here. If the system cannot take full disclosure
it is considered weak. Security though obscurity is a very bad idea.
