[boost] Including open source, non-copyright, no warranty in a boost library

Hello, I'm working on refactoring boost::uuids::name_generator to have a configurable hash algorithm through a template concept. RFC 4122 allows for two hashing algorithms, MD5 and SHA1. The current implementation only does SHA1, however I want to add MD5 for completeness (and I want to prepare for the eventual successor to SHA1 in the next RFC for UUID). I found an open source MD5 implementation of RFC 1321 at the following location and I was wondering if there are rules against bringing it into boost as a detail implementation? http://openwall.info/wiki/people/solar/software/public-domain-source-code/md... Thanks, Jim
