Question

Find out how can we use cryptography libraries in Python. Write down the steps to install cryptography library in Python.

Answer 1

Answer:

To use cryptography libraries - import cryptography

(or)

from cryptography.fernet import Fernet

To install cryptography on windows, simply open administrative command prompt and type -

$ pip install cryptography

To install cryptography on Linux,  cryptography ships manylinux wheels (as of 2.0) so all dependencies are included. For users on pip 8.1 or above running on a manylinux1 or manylinux2010 compatible distribution (almost everything except Alpine) all you should need to do is:

$ pip install cryptography

If you are on Alpine or just want to compile it yourself then cryptography requires a compiler, headers for Python (if you’re not using pypy), and headers for the OpenSSL and libffi libraries available on your system.

For Ubuntu, we need to type this command:-

$ sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

For CentOS-

$ sudo yum install redhat-rpm-config gcc libffi-devel python-devel \
    openssl-devel

Let me know if you have any doubts or if you need anything to change.
