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
http://www.cnds.jhu.edu/research/group/secure_spread/

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