| IDEA vector creation |
| ===================== |
| |
| This page documents the code that was used to generate the IDEA CBC, 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`_. |
| |
| Creation |
| -------- |
| |
| ``cryptography`` was modified to support IDEA in CBC, CFB, and OFB modes. Then |
| the following python script was run to generate the vector files. |
| |
| .. literalinclude:: /development/custom-vectors/idea/generate_idea.py |

| |
| |
| Verification |
| ------------ |
| |
| The following Python code was used to verify the vectors using the `Botan`_ |
| project's Python bindings. |
