**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

You will also need to configure this dependency:

```
dependencies {
  implementation "org.bouncycastle:bcprov-jdk15on:1.65"
}
```

 * [application interceptor][OkHttpClient.interceptors] or as a [OkHttpClient.networkInterceptors].
 *
 * The format of the logs created by this class should not be considered stable and may
 * change slightly between releases. If you need a stable logging format, use your own interceptor.
