ARC4 vector creation
====================
This page documents the code that was used to generate the ARC4 test
vectors for key lengths not available in :rfc:`6229`. All the vectors
were generated using OpenSSL and verified with Go.
Creation
--------
``cryptography`` was modified to support ARC4 key lengths not listed
in :rfc:`6229`. Then the following Python script was run to generate the
vector files.
.. literalinclude:: /development/custom-vectors/arc4/generate_arc4.py
Download link: :download:`generate_arc4.py
</development/custom-vectors/arc4/generate_arc4.py>`
Verification
------------
The following Go code was used to verify the vectors.
.. literalinclude:: /development/custom-vectors/arc4/verify_arc4.go
:language: go
Download link: :download:`verify_arc4.go
