OkHttp TLS
==========

Approachable APIs for using TLS.

A [`HeldCertificate`][held_certificate] is a certificate and its private key. Use the
[builder][held_certificate_builder] to create a self-signed certificate that a test server can use
for HTTPS:

```java
HeldCertificate localhostCertificate = new HeldCertificate.Builder()
    .addSubjectAlternativeName("localhost")
    .build();
```
