Review Comment:
Instead of throwing here would it not make sense to try and get an instance
via something like `return MessageDigest.getInstance(digest.getAlgorithm());`
and only throw if that fails?

> Optimize authentication cache key creation

> Currently the process to create an authentication cache key involves _always_
> invoking {{java.security.MessageDigest#getInstance(java.lang.String)}}. This
> isn't strictly necessary. We can use a pattern similar to
> {{org.apache.activemq.artemis.protocol.amqp.sasl.scram.ScramServerFunctionalityImpl}}
> which uses {{clone()}} on the {{MessageDigest}} to avoid invoking
> {{getInstance}} every time.
> Also, we can hash fewer bytes and avoid unnecessary String concatenations by
> inspecting each part of the input and only adding bytes that actually make a
> difference to the final hash.
> These are relatively minor improvements, but are simple and still worth doing.
