There Is no real way to do this in Microformats (as far as I know) but
there has been some work on hashes[1] and digital signatures[2], you are
maybe even asking the wrong community, and you should maybe ask the
RDFa[3] community as what you are asking is possible in RDFa:

<a property="foaf:sha1sum" href="mailto:their at name.com" rel="contact"
content="052f384479559f1b4854756bdce69d1c658de3b3">Their Name</a>
