URL Encoder 1.0 (Windows)
From the developer: "URL Encoder turns plain-text web addresses into obfuscated, illegible URLs. Protect yourself against your employer, ISP, or government searching for "key words" in web access logs. For example, http://winfosec.com becomes http://%77%69%6E%66%6F%73%65%63%2E%63%6F%6D which cannot be read by a human or searched for 'key words.' URL Encoder is totally free!"
