How to recover password
Salam
Dear mohsan1987,
Use John the Ripper to crack encrypted password , or you can say translate encrypted password into readable format .

Well if the password in shadow is hashed MD5 or SHA1 (which it is not so) then you cannot recover it as hashing is a one way function that is it is not reversable, that is why sometimes if you forget your passwords at YAHOO! or Hotmail they reset your passwords. Anyways the password in shadow file is encrypted using DES algorithm. You can view that also from
man crypt
You can easily create a C program to create your own implementation of extracting password from shadow file.

unless you know of a bug in des that no one else knows about, there is no way to go from the encrypted password in /etc/passwd or /etc/shadow to the original text. are you aware that des is used as a one-way hash for the passwords? read the source code to the crypt code.LinuxNerd wrote:You can easily create a C program to create your own implementation of extracting password from shadow file.
err BUG give me break... DES is an encryption algorithm. There is a world apart difference between encryption and hashing. Encrypted text can be decrypted, but hashing is a one way function. You need to study cryptography to get that, linux wont explain that. By the way RSA and DSA (these are much better than DES, 3DES, Rijndael, RC5, AES, ...) can be decrypted as well. I leave that part for the learned here to think and figure out how. Googling can solve lots of your woes, it would tell you how can you encrypt and decrypt these implementations. To calculate hashes (MD5 or SHA1 namely) is what we call in modern day world brute force or dictionary based password cracking, which some tools do used as mentioned in one of the recent posts. So it isnt impossible, it is just that we are unaware.
