Re: [TLS] [Cfrg] V1.1 of MSR ECCLib for NUMS Curves library released (now supporting GCC on Linux)

Hi Hannes,

Thanks very much for your interest and yes we are working on a portable C version but it's not quite ready yet.  As soon as it's done & posted I'll send out another announcement.

Hi Brian,

thanks for sharing the code.

I am wondering whether you also have a version that does not make use of assembler code since I cannot run this code on 32-bit ARM processors.

Ciao
Hannes
