I'm working on a Java project where I should implement the SSL-protocol on the server-side. This is the first time I will use SSL in my application, so I read a lot about SSL/TLS, and now I want to implement something in Java. I will implement this process using the JSSE API:

1. Client will connect to me
2. I will authenticate with my pubic key certificate. I means that I will send the client a public key and its corresponding certificate
3. The client encrypts the secret-key using my public key and RSA-algorithm and send it to me

I already have the private key and certificate saved on a keystore on my computer. So I am hesitated how to access them from my Java application. I do not know, which are the steps to do to access them, since it is the first time I'm dealing with this kind of stuff

I will use an `SSLEngine`. So I should first initialize an `SSLContext` using this code:

```
// First initialize the key and trust material.
KeyStore ksKeys = KeyStore.getInstance("JKS");
ksKeys.load(new FileInputStream("/.../myKey"), passphrase);
KeyStore ksTrust = KeyStore.getInstance("JKS");
ksTrust.load(new FileInputStream("/../myCertificate"), passphrase);

sslContext = SSLContext.getInstance("TLS");
sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null);
// We're ready for the engine.
SSLEngine engine = sslContext.createSSLengine(hostname, port);

// Use as client
engine.setUseClientMode(true);

```

I'm really new to cryptography, and this is the first time I programming this stuff. Any idea?
