De-Obfuscator

Some spam contains URLs and other text that has been obfuscated by applying URL (%xx) or HTML (&#ddd;) encoding. They sometimes also add a fake domain in the (otherwise rarely used) username/password field of the http url.

It is sometimes useful to be able to decode this stuff without loading it into a browser. Here's a tool to do (some of) that, in case anyone else out there has the same requirement.

Unfortunately for some, it's written in Java 1.4 because I wanted regular expressions. If enough people complain they can't use it, I'll re-do it in an earlier version.

This version has been updated to operate on multiple lines, since it has become more common for spam to contain multiple lines of obfuscated text. It is also now under the GNU GPL.
