hey,
i encountered some problem here...
it was 2 days i tried to search on internet about what does ubuntu use for encrypting a password?
i tried with md5 hash generator and i did try with des generator..but the encrypted password that was produced by these two generator is not the same as mine..
one more questions?
i read on internet,if in etc/shadow,there is $1$ before our encrypted password,it means the password is encrypted by using md5.
in my case,there is $6$.what does this $6$ mean and which type of password encryption does it use?

regards
nik

Hi,

This: $1$ or $6$ show the id's.

ID meaning:
If you see $6$ then SHA-512 is used.

Source of information: Ubuntu manuals: karmic (3) crypt.3.gz

Hope this helps.

To add to the previous poster here is the syntax of your password in /etc/shadow:
$id$salt$encrypted

Where ID is the algorithm used:
0-DES, 1->MD5, 2a->Blowfish, 5->SHA-256, 6->SHA512

Below is en example of what you can find in my /etc/shadow (some what modifyed )
