prime256v1

prime256v1 is the OID of the P-256 curve (secp256r1) in keys and certificates.

1.2.840.10045.3.1.7 identifies prime256v1, named elliptic-curve domain parameters. DER: 06082a8648ce3d030107.

OpenSSL prints this OID as prime256v1, its ANSI X9.62 name; TLS and SEC 2 call the same curve secp256r1 and NIST calls it P-256. See P-256.
