Jkain
Jkain is a free (as in free beer) fast hash reverser (MD5 & SHA-1) designed primarily for security analysts and penetration testers for risk assessment support. From ordinary databases where the passwords are stored hashed but unsalted Jkain will most likely be able to reverse about 50-75% of the hashed passwords in just matters of seconds, this because Jkain is using online rainbow tables.
