SEC 2 Version 1.0 — Recommended Elliptic Curve Domain Parameters
SECG's 2000 catalogue defines named prime-field and binary-field curve parameter sextuples, including secp256k1 and secp256r1, plus identifiers and then-current strength mappings.
SEC 2 specifies each prime-field curve as and gives interoperable encodings, names, and OIDs. Its secp256k1 parameters remain consensus-relevant to Bitcoin and Ethereum, while secp256r1 is the same curve commonly called P-256 in NIST contexts.
Version 1.0 also lists small curves, binary curves, SHA-1-based generation descriptions, and cross-standard status as of 2000. Those tables are not present recommendations; use SEC 2 v2 and NIST SP 800-186 for current parameter guidance.

All 51 physical pages were rendered and inspected. The document contains parameter and interoperability tables rather than explanatory diagrams. The 256-bit strength row and parameter sextuple are synthesized into the ECC entry; no source visual is retained.
