HowToMakeAnSha1Sum
From FOAF
Make an email into into an sha1sum!
echo -n mailto:me@mydomain.com | sha1sum
There are also online tools:
* sbp's sha1sum (Python) * earle's sha1sum (Perl) * mortenf's sha1ify (PHP)
Issues to clarify: what level of case normalisation to perform? Is there an open issue on this?
It might be a good idea to combine this information with that at HashPrograms.
