// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Create a Fortuna PRNG and seed it with system entropy.
// This will be our source of random data for generating the ECC private key.

Dim entropy As String

// Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.
