| SECP256K1 vector creation |
| ========================= |
| |
| This page documents the code that was used to generate the SECP256K1 elliptic |
| curve test vectors as well as code used to verify them against another |
| implementation. |
| |
| |
| Creation |
| -------- |
| |
| The vectors are generated using a `pure Python ecdsa`_ implementation. The test |
| messages and combinations of algorithms are derived from the NIST vector data. |

| |
| |
| Verification |
| ------------ |
| |
| ``cryptography`` was modified to support the SECP256K1 curve. Then |
| the following python script was run to generate the vector files. |
