Secure Spread is currently using Blowfish, which encrypts 64-bit blocks.
It can increase the size of your message if the message size is not a multiple
of 8 bytes.  I don't think that this increase is significant, it depends what do

you mean by a small mesage.

There are a couple of papers, and also we have released a Secure Spread
version some months ago. All the information and the code are available at

Secure Spread is an ongoing research project so we are interested in any
comments or suggestions.
