53 Example X.509 compatible 34.10-2012 keypair generation, signing and
54 verifying its signature:
57 >>> from pygost import x509
58 >>> prv, pub = x509.keypair_gen(urandom(64), mode=2012)
59 >>> data = b'some data'
60 >>> signature = x509.sign(prv, data, mode=2012)
61 >>> x509.verify(pub, data, signature, mode=2012)

67 mailing list. Announcements also go to this mailing list.
74 No additional dependencies except Python 2.7/3.x interpreter are required.
76 Preferable way is to download tarball with the signature:
79 % wget http://www.cypherpunks.ru/pygost/pygost-2.3.tar.xz
80 % wget http://www.cypherpunks.ru/pygost/pygost-2.3.tar.xz.sig
81 % gpg --verify pygost-2.3.tar.xz.sig pygost-2.3.tar.xz
82 % xz -d < pygost-2.3.tar.xz | tar xf -
84 % python setup.py install

102 But also you can use PIP (@strong{no} authentication is performed!):
105 % pip install pygost==2.3
108 You @strong{have to} verify downloaded tarballs integrity and
109 authenticity to be sure that you retrieved trusted and untampered
110 software. @url{https://www.gnupg.org/, The GNU Privacy Guard} is used
113 For the very first time it it necessary to get signing public key and
114 import it. It is provided below, but you should check alternative
