This page documents the code that was used to generate the SEED CFB and OFB test vectors as well as the code used to verify them against another implementation. The vectors were generated using OpenSSL and verified with Botan.
cryptography was modified to support SEED in CFB and OFB modes. Then the following python script was run to generate the vector files.

The following Python code was used to verify the vectors using the Botan project's Python bindings.
