| The key, message, and signature come from: |
| http://csrc.nist.gov/groups/STM/cavp/documents/dss/186-3ecdsatestvectors.zip (SigVer.rsp) |
| |
| The algorithm DER was synthesized to match, and the signature (provided as an r |
| and s tuple) was encoded into a Ecdsa-Sig-Value and then a BIT STRING. |
| |
| It uses ECDSA verification, using curve prime256v1 and SHA-512 |
