/**
* <p>
* SSLProtocolSocketFactory can be used to validate the identity of the HTTPS
* server against a list of trusted certificates and to authenticate to the HTTPS
* server using a private key.
* </p>
*
* <p>
* SSLProtocolSocketFactory will enable server authentication when supplied with
* a {@link KeyStore truststore} file containg one or several trusted certificates.
* The client secure socket will reject the connection during the SSL session handshake
* if the target HTTPS server attempts to authenticate itself with a non-trusted
* certificate.
* </p>
*
* <p>
* Use JDK keytool utility to import a trusted certificate and generate a truststore file:
* <pre>
* keytool -import -alias "my server cert" -file server.crt -keystore my.truststore
* </pre>
* </p>
*
* <p>
* SSLProtocolSocketFactory will enable client authentication when supplied with
* a {@link KeyStore keystore} file containg a private key/public certificate pair.
* The client secure socket will use the private key to authenticate itself to the target
* HTTPS server during the SSL session handshake if requested to do so by the server.
* The target HTTPS server will in its turn verify the certificate presented by the client
* in order to establish client's authenticity
* </p>
*
* <p>
* Use the following sequence of actions to generate a keystore file
* </p>
* <ul>
* <li>
* <p>
* Use JDK keytool utility to generate a new key
* <pre>keytool -genkey -v -alias "my client key" -validity 365 -keystore my.keystore</pre>
* For simplicity use the same password for the key as that of the keystore
* </p>
* </li>
* <li>
* <p>
* Issue a certificate signing request (CSR)
* <pre>keytool -certreq -alias "my client key" -file mycertreq.csr -keystore my.keystore</pre>
* </p>
* </li>
* <li>
* <p>
* Send the certificate request to the trusted Certificate Authority for signature.
* One may choose to act as her own CA and sign the certificate request using a PKI
* tool, such as OpenSSL.
* </p>
* </li>
* <li>
* <p>
* Import the trusted CA root certificate
* <pre>keytool -import -alias "my trusted ca" -file caroot.crt -keystore my.keystore</pre>
* </p>
* </li>
* <li>
* <p>
* Import the PKCS#7 file containg the complete certificate chain
* <pre>keytool -import -alias "my client key" -file mycert.p7 -keystore my.keystore</pre>
* </p>
* </li>
* <li>
* <p>
* Verify the content the resultant keystore file
* <pre>keytool -list -v -keystore my.keystore</pre>
* </p>
* </li>
* </ul>
