@node Download
@unnumbered Download

Preferable way is to download tarball with the signature from
website and, for example, run tests with benchmarks:

@verbatim
% wget http://www.cypherpunks.ru/gogost/gogost-1.1.tar.xz
% wget http://www.cypherpunks.ru/gogost/gogost-1.1.tar.xz.sig
% gpg --verify gogost-1.1.tar.xz.sig gogost-1.1.tar.xz
% xz -d < gogost-1.1.tar.gz | tar xf -
% make -C gogost-1.1 bench
@end verbatim

You @strong{have to} verify downloaded tarballs integrity and
authenticity to be sure that you retrieved trusted and untampered
software. @url{https://www.gnupg.org/, The GNU Privacy Guard} is used
for that purpose.

For the very first time it it necessary to get signing public key and
import it. It is provided below, but you should check alternative
resources.
