I have no access to a good computer so it is impossible to crack a hash in a reasonable amount of time. Thanks in advance. Also, post what dictionary you used and which program.

hash1: 2B74D47199B354D472437CCB57040A21FACB72CF4B5B0AF4
hash2: 003AA2321FE6379EF15DB450CA50D8A3FA735E92631EFD66

Thanks!,
Apollo

Salted? Where is salt then? And what algorithm?

ApolloJain · Beginner

I believe the algorithm to be SHA-1

They are from Mac OSX 10.4.11 and were extracted using MacKrack

Does that help at all? Smile

Also, I thought the salt was the first 6 digits but IDK for sure. Confused

Excuse my pun

I imagine the passwords being between 7 and 10 but they could probably be anywhere from 5 to 12.

I found good article about such hashes:

http://www.dribin.org/dave/blog/archives/2006/04/28/os_x_passwords_2/

... and i'm trying right now some tricks in order to be able to crack them with passwordspro. But there is no guarantee of course. And there was information, that JohnTheRipper is able to crack this hashes - i suggest to look at it.

Would online SHA-1 rainbow table be put to any use or not

in Sha-1 salt algorithm, isn't the format SALTPASSWORD
so if your password was qwerty with a salt of 12345 wouldn't it be hashed Sha1 as 12345qwerty and if you took off the salt of the front of the hash you could search it in a rainbow table and if the rainbow table had 12345qwerty could you find it?

I ramble. Rolling Eyes

In case of MacOSX SHA-1 salted hashes you can't use traditional rainbow tables, because salt is 4 bytes of binary data. Chances are, that all four bytes of salt are alpha or alphanumeric or something like that, but in most cases those 4 bytes are containing non-traditional characters. For example, in one of your salts there is binary zero. So in other words you can't find downloadable rainbow tables with such charset (all 256 char variations) and building them yourself is not helping either, because they will be too big and performance too poor.
Only real choices are bruteforce and wordlist methods. I tried all my wordlists and some limited bruteforce and got no success. If the password is strong enough, then it's very hard to crack or it can be virtually uncrackable in case of very good password ...

Well, well, well...what do we have here? It seems Apollo wants to extract the root pass for our iBooks! Heh heh searching the pass on Google automatically came to this thread, seems like waraxe has a pretty good PageRank. Smile

I've been following this thread for a couple days now Apollo...seems you've gotten just as far as me. Wink

I've found the exact same hash hidden in var/db/shadow/hash/<guid>
