Reversing django.contrib.auth.models.User password, sha1 to readable string

Question

from django.contrib.auth.models import User
u = User.objects.get(username='test')
user.password
u'sha1$c6755$66fc32b05c2be8acc9f75eac3d87d3a88f513802

Is reversing this password encryption possible?

Answer 1

Yes, it's possible. All you need is a few million years, and a computer the size of our solar system.

Answer 2

Sha-1 is a one-way hash. It cannot be reversed except for using a brute force attack which will take millions of years.

There are some online databases that let you reverse the hash of common words/conbinations of words. However, django adds "salt" to the password before it computes the hash, so you cannot reverse django passwords.

That's why a hash is used. Nobody can find out your password, not even sys admins :-)

Answer 3

No, that's the point.

If your user forgot their password, you'll have to reset it.
