[Cryptography-dev] Recipe for files?

[Stefan Pochmann]

I like the Fernet recipe, but I'd like a better recipe for files. One that
doesn't want the entire message at once (bad for big files) and that
doesn't bloat with base64. Should I do it myself with "hazardous materials"
(I might adapt the Fernet code) or will you maybe add such a recipe soon?

Something like this maybe:

f = SomethingLikeFernetButForFiles(key)
for block in f.encrypt(filename, blocksize):
    myhandling(block)

Or with a handler parameter:

f = SomethingLikeFernetButForFiles(key)
f.encrypt(filename, blocksize, myhandling)
