wolfcrypt: the wolfSSL Crypto Engine
====================================
**wolfCrypt Python**, a.k.a. ``wolfcrypt`` is a Python library that encapsulates
**wolfSSL's wolfCrypt API**.
`wolfCrypt <https://wolfssl.com/wolfSSL/Products-wolfcrypt.html>`_ is a
lightweight, portable, C-language-based crypto library
targeted at IoT, embedded, and RTOS environments primarily because of its size,
speed, and feature set. It works seamlessly in desktop, enterprise, and cloud
environments as well. It is the crypto engine behind `wolfSSl's embedded ssl
library <https://wolfssl.com/wolfSSL/Products-wolfssl.html>`_.
Installation
------------
In order to use ``wolfcrypt``, first you'll need to install ``wolfssl`` C
embedded ssl library.
Installing ``wolfssl`` :
~~~~~~~~~~~~~~~~~~~~~~~~
**Mac OSX**
.. code-block:: console
brew install wolfssl
or
.. code-block:: console
git clone https://github.com/wolfssl/wolfssl.git
cd wolfssl/
./autogen.sh
./configure --enable-sha512
make
sudo make install
**Ubuntu**
.. code-block:: console
sudo apt-get update
sudo apt-get install -y git autoconf libtool
git clone https://github.com/wolfssl/wolfssl.git
cd wolfssl/
./autogen.sh
./configure --enable-sha512
make
sudo make install
sudo ldconfig
**CentOS**
.. code-block:: console
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-6.noarch.rpm
sudo yum update
sudo yum install -y git autoconf libtool
git clone git@github.com:wolfssl/wolfssl.git
cd wolfssl
./autogen.sh
./configure --enable-sha512
make
sudo make install
echo /usr/local/lib > wolfssl.conf
sudo mv wolfssl.conf /etc/ld.so.conf
sudo ldconfig
Installing ``wolfcrypt`` :
~~~~~~~~~~~~~~~~~~~~~~~~~~
**Mac OSX**
.. code-block:: console
sudo -H pip install wolfcrypt
**Ubuntu**
.. code-block:: console
sudo apt-get install -y python-dev python3-dev python-pip libffi-dev
sudo -H pip install wolfcrypt
**CentOS**
.. code-block:: console
sudo yum install -y python-devel python3-devel python-pip libffi-devel
sudo -H pip install wolfcrypt
Testing ``wolfcrypt`` :
~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: console
python -c "from wolfcrypt.hashes import Sha; print Sha().hexdigest()"
expected output: **da39a3ee5e6b4b0d3255bfef95601890afd80709**
Testing ``wolfcrypt``'s source code with ``tox`` :
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To run the unit tests in the source code, you'll need ``tox`` and a few other
requirements. The source code relies at 'WOLFSSL_DIR/wrapper/python/wolfcrypt'
where WOLFSSL_DIR is the path of ``wolfssl``'s source code.
1. Make sure that the testing requirements are installed:
.. code-block:: console
$ sudo -H pip install -r requirements-testing.txt
2. Run ``tox``:
.. code-block:: console
$ tox
...
_________________________________ summary _________________________________
py27: commands succeeded
SKIPPED: py34: InterpreterNotFound: python3.4
py35: commands succeeded
congratulations :)
Note: the test is performed using multiple versions of python. If you are
missing a version the test will be skipped with an **InterpreterNotFound
error**.

Asymmetric Key Algorithms
=========================
.. module:: wolfcrypt.ciphers
**Asymmetric key algorithms** are encryption algorithms that use **a pair
of cryptographic keys**, one for data encryption and signing and the other
one for data decryption and signature verification.
``wolfcrypt`` provides access to the following **Asymmetric Key Ciphers**:

Message Digests
===============
.. module:: wolfcrypt.hashes
A **message digest** is the output of a **cryptographic hash function**
containing a string of bytes created by a **one-way formula** using the
original message as input.
Message digests are designed to protect the integrity of a piece of data or
media to detect changes and alterations to any part of a message.

Message Authentication Codes
============================
.. module:: wolfcrypt.hashes
A **message authentication code** (MAC) is a short piece of information used
to authenticate a message — in other words, to confirm that the message came
from the stated sender (its authenticity) and has not been changed in transit
(its integrity).
``wolfcrypt`` implements the **Hash-based message authentication code** (HMAC),
which uses a cryptographic hash function coupled with a secret key to produce
**message authentication codes**.

Random Number Generation
========================
A **cryptographically secure pseudo-random number generator** (CSPRNG) is a
**pseudo-random number generator** (PRNG) with properties that make it suitable
for use in cryptography.
Using the standard random module APIs for cryptographic keys or initialization
vectors can result in major security issues depending on the algorithms in use.
``wolfcrypt`` provides the following CSPRNG implementation:
.. module:: wolfcrypt.random

>>> from wolfcrypt.random import Random
