// 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:
CkoPrivateKey *privKey = [[CkoPrivateKey alloc] init];

// Pass an empty password if not needed.
NSString *password = @"";
BOOL success = [privKey LoadAnyFormatFile: @"qa_data/eddsa/ed25519.pem" password: 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: password];

// The same for public keys..
// (public keys never have nor need passwords)
CkoPublicKey *pubKey = [[CkoPublicKey alloc] init];
success = [pubKey LoadFromFile: @"qa_data/pubkeys/pubkey_pkcs1.der"];
