Please let me know how can I translate it from Java to Pascal!

//create random demonstration ECC keys
KeyPairGenerator kpg = KeyPairGenerator.getInstance("EC");
kpg.initialize(256); //256 bit ECDSA key

//create a key pair for the demo Certificate Authority
KeyPair caKeyPair = kpg.generateKeyPair();

//get references to private keys for the CA and the signing key
PrivateKey caKey = caKeyPair.getPrivate();

Greetings and thanks for your help.

Thank you for contacting us.

You can use our TElECKeyMaterial class and its Generate method. Details: https://www.eldos.com/documentation/sb...erate.html

Code sample:

var Km: TElECKeyMaterial;
  Km := TElECKeyMaterial.Create;
  // then use Km instace with TElECDSAPublicKeyCrypto to sign data
