AES CFB 256 Encryption method

2006-08-18 Thread David Irvine
Ok I have taken comment so far and this is my plan - if I am way off please let me know create a public salt (anyone can see this and will) of X length (128bits) take sha512 hash of file to be encryted (and keep it) supply a password to the pbkdf2 - to create a 256bit key for my AES256 CFB
