If I have understood correctly, Twofish is more secure (harder to break) than AES and Camellia, but it's slower than both.
How can I measure the speed difference between AES vs Twofish and Camellia vs Twofish? Does Twofish use twice as much time? Half as much time? Or does it just take a few percent longer to encrypt/decrypt than AES/Camellia?
I'm in the starting/planning phase of software development: the local stored data will be encrypted, and the data to be transmitted over a network will be encrypted/signed. I would like to use Twofish as the symmetric cipher, but if it uses twice the resources of AES/Camellia, then it's not a good idea.
