Encryption of large files using symmetric ciphers.

[tomilov]

There is a task, which all the similar libraries should be able to solve: encryption of a large files.

As an example of a good interface lets look at QCryptographicHash. Its QCryptographicHash::addData(QIODevice *) can process whole file not putting it into the memory entirely.

Is it possible to porcess large files with QPolarSSL having low memory footprint?
