Hi Guys!

I need help again.
I not understand this method. I probe cracking RAR file. I stopped the first steps.
How can I extract or find the hash file from RAR file - what can I cracking.

When I use this program:

http://www.servetrue.com/md5extractor.php

I open with password protected RAR file. The program give me example:

MD5: 1645486C13EAF0D0EE6181BECA67B8FD
SHA1: 51A182EAD5823D3135B7256F2E5A1257EACB1F75

This is "that" hash file? I crack it and I have the password for archive, or this is other hash.
And this case, what program can I extract the correct hasch file, for cracking?

well, MacGyver might be able to do what you try, but no normal people. Really.

Sure you're right...
I just not understand the method. There is a rar file - SHA1 128Bit crypting.
How can I get the hash from rar file?

The question is maybe wrong...
Okay, maybe this:

Can I extract at all HASH from encrypted rar file? Example: crack with rainbow tables

or

just bruteforca cracking work?

Try using JtR jumbo version from https://github.com/magnumripper/magnum-jumbo for cracking RAR files.

1. Compile and run rar2john on the RAR file.
2. Run john on output of step 1.

JtR jumbo supports cracking RAR files using GPU too. However, cracking RAR files is extremely slow.
