Curve OIDs

This page contains an overview of elliptic curves and their corresponding ASN.1 Object Identifiers (OIDs).

When creating an elliptic curve key (algorithm "EC" or "ED"), you need to specify the OID to select the curve. This is similar to how you need to specificy a key size (such as 4096) when creating a key with algorithm "RSA".
