(PHP ActiveX) Generate an ECC Key

Demonstrates how to generate an ECC key.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// All Chilkat classes can be unlocked at once at the beginning of a program
// by calling UnlockBundle.  It requires a Bundle unlock 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.

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