`certificatePem()` method encodes the certificate in the familiar PEM format
    (`--- BEGIN CERTIFICATE ---`); the `privateKeyPkcs8Pem()` does likewise for the private key.

    `HandshakeCertificates` holds the TLS certificates required for a TLS handshake. On the server
    it keeps your `HeldCertificate` and its chain. On the client it keeps the root certificates

 * They specify that the call may be plaintext (`http`) or encrypted (`https`), but not which cryptographic algorithms should be used. Nor do they specify how to verify the peer's certificates (the [HostnameVerifier](https://developer.android.com/reference/javax/net/ssl/HostnameVerifier.html)) or which certificates can be trusted (the [SSLSocketFactory](https://developer.android.com/reference/org/apache/http/conn/ssl/SSLSocketFactory.html)).
