shadow file
 

hi

are there a way to get password with the shadow file?

thanks

Short answer: No. Hashes are one-way. They can not be reversed (in theory).

Long answer: You can run a dictionary attack / brute force attack against your own /etc/shadow file if you are really desparate.

Real answer: Explain your situation more. There are probably better ways to accomplish what you want.

If you just want to reset a password then just delete the password hash - leave it as nothing (ie. not space between the two colons).

There is an exploit that will dump the contents of /etc/shadow so you can brute force the hash much better. This depends on the kernel version as it exploits the binfmt handler. However I can't post it here as it would violate forum rules. Besides isn't this like your assignment like you said in the other thread. That is also against forum rules. :)

We won't make your homework for you, google a bit.
