This beautiful widget allows you to make MD5 and other encryptions on the fly. My house friends and I use it to create WEP, WPA, etc passwords for each other when we need.
You and a buddy need to encrypt your comp-to-comp network for a quick project. You do not want to leave it unsecured, so you both open ladycrypt and make an MD5 26 character password from the name of your favorite SciFi eye candy (or his really hot sister you have teased him about since the 5th grade). Next thing you know, you have a pretty darn secure network, relatively speaking!
