But also you can use PIP (@strong{no} authentication is performed!):

@verbatim
% pip install pygost==3.14
@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 is necessary to get signing public key and
import it. It is provided below, but you should check alternative
