RAR password cracking

I saw a pdf cracker, Which removes the password ( 256 bit encrypted) within seconds. When a pdf cracker cracks the password in seconds, why don't a RAR password cracker takes hours to crack a file. If we found out where a RAR file stores the password exactly we can easily break that too?? Any ideas?

 

I think it's got something to do with the compression algorithm that makes it takes longer.

 

Is there any way to hex edit a RAR file and remove the password

 

try olly at this link, it has helped me couple of times http://www.hellboundhackers.org/downloads.php?cat_id=10

 

If i hex edit a RAR file, when i try to open it again. it says "HEADER CORRUPT or MISSING".

I have "not" used it,so make sure to scan it ok. I found you 2 links,hope it helps you in anyway,and i hope im not breaking the rulez.

or try :This other link

I checked both links before posting and are working

 

Also this tool is very handy, can crack a couple of compresses file formats: http://packetstormsecurity.org/Win/archpr.zip

 

I already have this thing man. But when i try to crack a password say(123forgo~oo) It shows the ETA as (194 days 27 hrs 24 mins) I need a much more faster thing...

 

I have this tool also. But it takes much time to crack passwords.

 

Then try a hex editor, maybe you are lucky and see the password.

 

I don't know where exactly the passwords are stored. Thats wat the problem behind hex editing??

 

Give me the rar file so that I can try it using a hex editor or olly.
