TL;DR: This module is deprecated, use lowercase md5@>=2.x from now on.
For years, there has been a lot of confusion with this module since there were two MD5 modules on npm, one called "MD5" (uppercase, the module you are looking at) as well as one by AJ ONeal called "md5" (lowercase). With version 2.0.0, only the implementation in this git repository stays on NPM, but its name changes from uppercase to lowercase. Old versions of both modules are marked deprecated. From now on, please use lowercase md5 with versions >= 2.0.0.
