Bug#802259: ITP: libntru -- implementation of the public-key encryption

[richard@orvidia.fr]

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,
