(Classic ASP) Generate Brainpool EC Keys (BP256R1, BP384R1, BP512R1, ...)Demonstrates how to generate brainpool EC keys. The brainpool elliptic curve (EC) is a set of standardized elliptic curves defined for use in cryptographic applications. These curves are defined over finite fields and are widely used for implementing elliptic curve cryptography (ECC) algorithms. The brainpool curves were developed by the brainpool project, a collaborative effort initiated by the German Federal Office for Information Security (BSI) to define standardized elliptic curves with well-established security properties. Note: Requires Chilkat v9.5.0.98 or later.
