This md5(md5($salt).md5($pass)) hash means the WORLD to me! My dictionaries couldn't crack it though..  Whoever cracks this one is my hero!  Seriously though, I really need this hash to be cracked. At least give it a try. 
Also the hash doesn't contain any special characters. Just the alphabet and numbers.
Md5: 893bac0dbb511a580e28f8a6805aa2b3
Salt: Xdwe{
Big huge forever thanks in return,
Ryan |

| If you brute force it, tell me what you did. That way that's one less thing I have to try myself. I'm at 7 digits with lower case alphabet and numbers. So I've tried 1-6 with lower case alphabet and numbers.(Something you don't have to do now) My computer is slow though.(Or at least the program I'm using is) Any help is very much appreciated.(Even if you don't crack it) |

Wait a second... md5(md5($salt) . md5($pass))? In my opinion it's nearly impossible to crack such a hash. You already know the half of the password, okay. But actually the "password" you're searching (the hash of the "real password") contains 32 digits.
This means your "real" password is salted with a 32 byte long salt.
Due to the fact that one digit of a hash may be 0 to f, that makes a number of... 16^32 or 3,4028236692093846346337460743177e+38 possibilities, if I recall right.
Do you really want to try this? |

O.o;
You didn't do your research before you posted, did you? Programs, such as PasswordPro, can do it in reverse. They take the salt and hash it, then take the pass and hash it, then hash them together.(Or something like that) I've cracked IPB passwords within seconds.  But I've only done them with dictionaries.. So are you saying when you brute force an IPB hash that it's gonna contain 32 digits? I'll prove you wrong. I've got a 6 digit password in an IPB hash format. I'll try to brute force it, with the brute forcer set to 6 digits. BRB |

All passwords found!
Thus, you are wrong. 
So yes, whoever can help(And knows how) please do. |

Dictionary attack relies opn the hashing method being known, and all variables, including the password.. Since it hashes a password and matches it to the unknown password.. Then with a word list u can try most common passwords  |

Uh, mea culpa.
The 16^32 combinations aren't that wrong (if you had to crack ALL possible MD5s), but I didn't think about easily cracking the hashes by dictionary or bruteforce (and that way you'd just have to concatenate both hashes and MD5 that again)... Seems like I was too tired... :/
Sorry for the incidence. |

Haha, it's cool mate. I know no ones gonna wanna dedicate their computer to help me brute force this Md5 hash. So wish me luck. |
