I've been working on some simple file encryption/decryption programs
(using ssleay) recently and i have a few questions.
1. With a block cipher, when dealing with a binary file (or any file for
that matter), how do you deal with the remaining block if it's incomplete?
2. In the docs for ssleay, eric suggests using des_read_pw_string() to
obtain the plaintext key, then making a 16 byte hash of it using md5, then
sending it (in my case) to BF_set_key(). How is this better than simply
sending the plaintext key to BF_set_key()?
Any help, pointers, etc are appreciated.
Nick
