DOCS: Please provide example for encrypting in more than one call to encrypt()

[matthewmucker-vizio]

I'm facing, I think, the same issue reported in issue 342. I would like to encrypt a 100GB file by sending multiple 'chunks' of data to encrypt(). I'm finding that this only works if I pad every input chunk (even when a multiple of AES block size), and only when I decrypt using the input chunk size plus 16 bytes.

This means that the decrypt operation has to know the chunk size used by then encrypt operation, which seems likely to be wrong to me.

An example of encrypting a large file in the docs would be much appreciated.
