Test vectors
============

Testing the correctness of the primitives implemented in ``cryptography``
requires trusted test vectors. Where possible these vectors are
obtained from official sources such as `NIST`_ or `IETF`_ RFCs. When this is
not possible ``cryptography`` has chosen to create a set of custom vectors
using an official vector file as input.

Vectors are kept in the ``cryptography_vectors`` package rather than within our
main test suite.

Sources
-------

Project Wycheproof
~~~~~~~~~~~~~~~~~~

We run vectors from `Project Wycheproof`_ -- a collection of known edge-cases
for various cryptographic algorithms. These are not included in the repository
(or ``cryptography_vectors`` package), but rather cloned from Git in our
continuous integration environments.

We have ensured all test vectors are used as of commit
``2196000605e45d91097147c9c71f26b72af58003``.

Creating test vectors
---------------------

When official vectors are unavailable ``cryptography`` may choose to build
its own using existing vectors as source material.

Created Vectors

If official test vectors appear in the future the custom generated vectors
should be discarded.

Any vectors generated by this method must also be prefixed with the following
header format (substituting the correct information):
