The openssl program 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.
