// This example assumes the Chilkat API to have been previously unlocked.
// 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 := CkPrivateKey_Create();

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

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

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

CkPrivateKey_Dispose(privKey);
CkPublicKey_Dispose(pubKey);
