To be fair, all security is a form of security through obscurity. An encryption key is just very, very obscure. If this security feature could only be reproduced using a bunch of PhD chemists and millions of dollars of lab equipment, then the security can be considered to be pretty obscure. Even the strongest key based encryption system is vulnerable to brute force attacks if you have enough computer power.
