HKDF vector creation
====================
This page documents the code that was used to generate a longer
HKDF test vector (1200 bytes) than is available in :rfc:`5869`. All
the vectors were generated using OpenSSL and verified with Go.
Creation
--------
The following Python script was run to generate the vector files.
.. literalinclude:: /development/custom-vectors/hkdf/generate_hkdf.py
Download link: :download:`generate_hkdf.py
</development/custom-vectors/hkdf/generate_hkdf.py>`
Verification
------------
The following Go code was used to verify the vectors.
.. literalinclude:: /development/custom-vectors/hkdf/verify_hkdf.go
:language: go
Download link: :download:`verify_hkdf.go
</development/custom-vectors/hkdf/verify_hkdf.go>`
