See more Ed25519 Examples

Demonstrates how to load any format Ed25519 private or public key.

Note: Chilkat began support for Ed25519 keys in version 9.5.0.83

  //  See Global Unlock Sample for sample code.

  //  A private key, regardless of type or format (RSA, EC, DSA, Ed25519) can be loaded by
  //  calling LoadAnyFormat or LoadAnyFormatFile.

  //  Likewise, a public key, regardless of type or format can be loaded by calling
  //  LoadFromFile or LoadBd.

  //  For example:
  privKey := TPrivateKey.Create;

  //  Pass an empty password if not needed.
  password := '';
  success := privKey.LoadAnyFormatFile('qa_data/eddsa/ed25519.pem',password);

  //  For example, an encrypted PKCS8 key of any type (Ed25519, RSA, EC, etc.)
  password := 'secret';
  success := privKey.LoadAnyFormatFile('qa_data/rsa/pkcs8.key',password);

  //  The same for public keys..
  //  (public keys never have nor need passwords)
  pubKey := TPublicKey.Create;
  success := pubKey.LoadFromFile('qa_data/pubkeys/pubkey_pkcs1.der');
