(C#) Load PEM Public/Private Key into RSA Object

Demonstrates how to load a PEM key into the Chilkat RSA object.

Note: This example requires Chilkat v11.0.0 or greater.

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Rsa rsa = new Chilkat.Rsa();

// First demonstrate importing a PEM public key:
string publicKeyPem = "PEM public-key data goes here";
Chilkat.PublicKey pubkey = new Chilkat.PublicKey();

success = pubkey.LoadFromString(publicKeyPem);
if (success == false) {
    Debug.WriteLine(pubkey.LastErrorText);
    return;
}

success = rsa.UsePublicKey(pubkey);
if (success == false) {
    Debug.WriteLine(rsa.LastErrorText);
    return;
}

// Demonstrate importing a PEM private key:
string privateKeyPem = "PEM private-key data goes here";
Chilkat.PrivateKey privkey = new Chilkat.PrivateKey();

// If the private key PEM is protected with a password, then 
// call LoadEncryptedPem.  Otherwise call LoadPem.
success = privkey.LoadPem(privateKeyPem);
if (success == false) {
    Debug.WriteLine(privkey.LastErrorText);
    return;
}

success = rsa.UsePrivateKey(privkey);
if (success == false) {
    Debug.WriteLine(rsa.LastErrorText);
    return;
}

Debug.WriteLine("OK!");
