[suggestion/FAQ] Explain difference between passphrase and keyfile

[Shohreh]

Hello,

I don't know much about encryption, and for symmetric encryption, it took me a little while to understand the difference between using a passphrase or a keyfile.

For other newbies, I suggest adding a section the FAQ, eg."To encrypt a file for yourself (symmetric encryption), Kryptor will hash a phrase and/or a (key)file you provide as input, and use that hashing to actually encrypt the file. If you use a keyfile as the sole source, make sure it's well protected since it's all Kryptor needs to decrypt a file."

FWIW, I was looking for an alternative to AES Crypt (it was recently closed-sourced), 7zip (it doesn't prompt for a confirmation when encrypting!), and Picocrypt (neither the GUI nor the CLI can take a passphrase as a parameter, so I was unable to automate its use from a wxPython script).

Cheers,

Thank you for the feedback and for trying Kryptor.

I think this is already covered by the Best practices section/Tutorial. However, I'll tweak the wording of What's a keyfile? to explicitly say that it needs to be kept secret.

Thank you.
