The OpenSSL EC library provides support for Elliptic Curve Cryptography ( ECC ). It is the basis for the OpenSSL implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) and Elliptic Curve Diffie-Hellman (ECDH). Note: This page provides an overview of what ECC is, as well as a description of … See more The primary advantage of using Elliptic Curve based cryptography is reduced key size and hence speed. Elliptic curve based algorithms use significantly smaller key sizes than their non elliptic curve equivalents. The … See more First of all some terminology. We need to define what is meant by a field. In essence a field is a setof elements with operations defined for the elements of that set that equate to something like addition, substraction, … See more The parameters necessary for performing cryptographic operations for ECDH and ECDSA are simply the parameters required to set up the curve. Namely, the type of field e.g. prime (Fp) or … See more In principle there are many different types of field that could be used for the values x and y of a point (x, y).
