Generate an ECDSA Key

Demonstrates how to generate an ECDSA key. C#

bool success = false;

// 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.
Chilkat.Prng fortuna = new Chilkat.Prng();
string entropy = fortuna.GetEntropy(32,"base64");

Chilkat.Ecc ecc = new Chilkat.Ecc();

// Generate a random ECC private key on the secp256r1 curve.
// Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.
