Elliptic Curve

Cryptology relies on the difficulty of solving mathematical problems, such as the factor of large integers composed of two large prime numbers and the discrete logarithm of a random eliptic curve. This module provides low-level features of the latter. Elliptic Curve protocols can provide the same security with smaller keys.

There are 2 forms of elliptic curves, `Fp`

and `F2^m`

. These curves use irreducible
trinomial or pentanomial . Being a generic interface to a wide range of algorithms,
the cuves are generally referenced by `EcGroup`

. There are many built in groups
found in `Nid`

.

OpenSSL Wiki explains the fields and curves in detail at Eliptic Curve Cryptography.
