What is Security Through Obscurity?

 , updated on March 20, 2017
Security through obscurity is a design that relies on secrecy to remain secure. It is considered a poor practice as truly secure designs could be openly published and remain secure.


Encryption algorithms are commonly published openly. This makes them more secure over time as peers can review the algorithm and attackers try to find weaknesses in it.
A proprietary encryption algorithm with a secret design may be less secure as some details about its design may be discovered at any time that expose flaws.
