hey, obviously I am a n00b at this, but what are md5 hashes used for that makes people want to crack them? and how do you get hold of them? Confused

i will try to explain to you is simple words.

Most of the hashes posted in here are hashes that are stored into databases of web applications.

I forgat to mention :

from google:
A hash function h is a transformation that takes a variable-size input m and returns a fixed-size string, which is called the hash value h (that is, h = H(m)). Hash functions with just this property have a variety of general computational uses, but when employed in cryptography the hash functions are usually chosen to have some additional properties.
md5 is a hash function that gets an any h value input and returns a 32 characters hex output

md5 funtion is used to "encypt" the value of the password of the users of a web app. for example :
a user register to a website and his password is stored encypted in the database so that the only one that knows it is the specific user .. NOT even the owner of the site should know it.

Now , regarding your other questions how to get it.
Most of the exploits can execute sql statements and the return value at most of the cases is an md5 hash value.
So you may get from an execution the following info

username : admin
password : 31435008693ce6976f45dedc5532e2c1

the 31435008693ce6976f45dedc5532e2c1 is the md5 of the password of the user.

md5 was made to be one way.
but with various techniques like rainbow tables / dictionary attacks / online datbases / bruteforce attack ... the value is returned to the plain value which at the the above case is

31435008693ce6976f45dedc5532e2c1 resolves to thisismypassword

If someone hacks in to remote database or read privated files, then usernames and passwords can be considered as worthy data to be stolen. People tend to use same or similar passwords in many places and if you can get someone's password for some forum or blog, then same password can open many other "locks". Now, there were times, when passwords were stored as plain text. As for now, 21. century, most of the passwords are stored as hashes or even salted hashes. In this way, if hacker can steal your password's hash, he/she still does not know real, plain text password. But there comes better part - simple hashes can be 1) bruteforced, 2)cracked by wordlists, 3)cracked by rainbow tables.

Still i must admit, that IF password is very good, THEN hash cracking is not possible, period Smile
