Module openssl::ec [−][src]
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.
