I am going for my ethical hacking exam soon and I still can't get my head around why symmetric key encryption is classed as "Private/Secret Key encryption" when symmetric encryption uses the same key and asymmetric encryption (Public Key) uses a public and PRIVATE key.
I just remember by thinking "As symmetric encryption begins with an S that's Secret key and secret key doesn't have a public and secret (private) key because it's weird."
I'm hoping someone will help me think of this in a less confusing way.
