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.

HOTP from RFC 4226
TOTP from RFC 6238 (Note that an errata for the test vectors in RFC 6238 exists)

CMAC

AES-128, AES-192, AES-256, 3DES from NIST SP-800-38B

Poly1305

Test vectors from RFC 7539.

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):

# CAST5 CBC vectors built for https://github.com/pyca/cryptography
# Derived from the AESVS MMT test data for CBC
# Verified against the CommonCrypto and Go crypto packages
# Key Length : 128
