Quick Question about cypher object

[LazyCoder]

Just a quick question, does the length of the key determine how long it takes to encrypt/decrypt a file?

Interesting question, that. I imagine it would make some difference, but you wouldn't really notice it unless the file's particularly large.

There wouldn't be a problem with using a longer key but with a smaller key it might have to buffer more times so using a larger key might be quicker.

Unless you have a file that is shorter than the key where a smaller key would be quicker

It's a Quicktime movie that is just over a meg. I need it to be decrypted as fast as possible because it is a movie that is used to act as a transition between the different backgrounds in the main menu of my game.
