Oops -- I deleted the message mentioning the "hacker's guide" to picking
locks. Actually it's a locksmithing guide, if you're thinking of the MIT
document.

Anyone who's really interested might also look for a document called
"scrtlock.html" or "scrtlock.txt", by Steven Hampton, and which used
to be
on Stephen Hardman's page.
