/**
   * Returns a hash function implementing the Message Authentication Code (MAC) algorithm, using the
   * MD5 (128 hash bits) hash function and the given secret key.
   *
   * <p>If you are designing a new system that needs HMAC, prefer {@link #hmacSha256} or other
   * future-proof algorithms <a

It is not a full featured HTTP testing library that is developed standalone. It is not being actively developed
for new features. As such you might find your needs outgrow MockWebServer and you may which to use a
more full featured testing library such as [MockServer](https://www.mock-server.com/).
