4 Preferable way is to :ref:`download <download>` tarball with the
5 signature from `official website <http://pyderasn.cypherpunks.ru/>`__::
7 $ [fetch|wget] http://pyderasn.cypherpunks.ru/pyderasn-6.2.tar.xz
8 $ [fetch|wget] http://pyderasn.cypherpunks.ru/pyderasn-6.2.tar.xz.sig
9 $ gpg --verify pyderasn-6.2.tar.xz.sig pyderasn-6.2.tar.xz
10 $ xz --decompress --stdout pyderasn-6.2.tar.xz | tar xf -
12 $ python setup.py install
13 # or copy pyderasn.py (+six.py, possibly termcolor.py) to your PYTHONPATH
15 PyDERASN depends on `six <https://pypi.org/project/six/>`__ package
16 for keeping compatibility with Py27/Py35. It is included in the tarball.
17 You can also find it mirrored on :ref:`download <download>` page.
19 You could use pip (**no** OpenPGP authentication is performed!) with PyPI::
21 $ cat > requirements.txt <<EOF
22 pyderasn==6.2 --hash=sha256:TO-BE-FILLED
23 six==1.14.0 --hash=sha256:236bdbdce46e6e6a3d61a337c0f8b763ca1e8717c03b369e87a7ec7ce1319c0a
25 $ pip install --requirement requirements.txt
27 You have to verify downloaded tarballs integrity and authenticity to be
28 sure that you retrieved trusted and untampered software. `GNU Privacy
29 Guard <https://www.gnupg.org/>`__ is used for that purpose.
