update: there is now an easier way to do this as a js widget!
% sha1sum jcr-1.0.jar 86b984b459383c8d4ba911785afef426be8fca7e % sha1sum *.jar | sed 's,\([^ \t]*\) *.*,\1 \1,;s,^...,&/,;s,/...,&/,;s, ,/,;s,.*,http://xml.jar-czar.com/pub/&-jar-czar.xml,' http://xml.jar-czar.com/pub/86b/984/b459383c8d4ba911785afef426be8fca7e/86b984b459383c8d4ba911785afef426be8fca7e-jar-czar.xml % alias sha1_to_jar_car="sed 's,\([^ \t]*\) *.*,\1 \1,;s,^...,&/,;s,/...,&/,;s, ,/,;s,.*,http://xml.jar-czar.com/pub/&-jar-czar.xml,'" % sha1sum *.jar | sha1_to_jar_car http://xml.jar-czar.com/pub/86b/984/b459383c8d4ba911785afef426be8fca7e/86b984b459383c8d4ba911785afef426be8fca7e-jar-czar.xml
using search on jar-czar
Just plugin the sha1 into the url pattern: http://www.jar-czar.com/search?type=sum&text=SUM
ie, http://www.jar-czar.com/search?type=sum&text=000e21736b021c1f6033e6cd1484f504176069b4
It also works for md5sums too: http://www.jar-czar.com/search?type=sum&text=31f97f979d99308b6530b93338ca3b01
