Test vectors
============
Testing the correctness of the primitives implemented in each ``cryptography``
backend 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 to verify consistency between
implemented backends.
Vectors are kept in the `cryptography_vectors` package rather than within our
main test suite.
