How to create a private-public key pair

This article explains how to create a private-public key pair. Private-public key cryptography is a relatively new cryptographic approach whose distinguishing characteristic is the use of asymmetric key algorithms instead of symmetric key algorithms.

Every digital certificate has a pair of associated cryptographic keys.
This pair of keys consists of a private key and a public key.
A public key is part of the owner's digital certificate and is available for anyone to use. A private key, however, is protected by and available only to the owner of the key. This limited access ensures that communications that use the key are kept secure.
