Hi Tomasz,
I thought about that too before considering packaging it, but it looks
like it's dual licensed, and patents are only here to protect the
commercial part.
According to https://github.com/NTRUOpenSourceProject/ntru-crypto :
"Security Innovation, Inc., the owner of the NTRU public key
cryptography system, made the intellectual property and a sample
implementation available under the Gnu Public License (GPL) in 2013 with
the goal of enabling more widespread adoption of this superior
cryptographic technology. The system is also available for commercial
use under the terms of the Security Innovation Commercial License."
I'm not sure this allows us to package it in debian, but hopefully
someone here knows better than me.
Regards,
