Hash Hunters lets users post their passwords and offer a reward for a person who can convert it to the original password. The highest reward posted on Hash Hunters is 1.585 Bitcoins for an MD5 hash, which would be about US$209 according to the market price on the Mt. Gox exchange.

It doesn’t use “https,” which is a standard security technology that encrypts communication between a client and a server.”]
