| CAST5 vector creation |
| ===================== |
| |
| This page documents the code that was used to generate the CAST5 CBC, CFB, OFB, |
| and CTR test vectors as well as the code used to verify them against another |
| implementation. The CBC, CFB, and OFB vectors were generated using OpenSSL and |
| the CTR vectors were generated using Apple's CommonCrypto. All the generated |
| vectors were verified with Go. |
| |
| Creation |
| -------- |
| |
| ``cryptography`` was modified to support CAST5 in CBC, CFB, and OFB modes. Then |
| the following Python script was run to generate the vector files. |
| |
| .. literalinclude:: /development/custom-vectors/cast5/generate_cast5.py |

| |
| |
| Verification |
| ------------ |
| |
| The following Go code was used to verify the vectors. |
| |
| .. literalinclude:: /development/custom-vectors/cast5/verify_cast5.go |
| :language: go |
