Supported ECC Curves

The following table lists all supported Elliptic Curve Cryptography (ECC) curves and their Object Identifiers (OID, expressed in dot notation and byte format).

NOTE    When 'HSM Policy (12) – allow non-FIPS algorithms' is disabled, any curve of <112-bit strength will exclusively be allowed for signature verification.

Curve Name(s) OID (dot) OID (byte) Security Strength (bits)
