pls could any one resolve this. thanks

It looks like you're trying to implement your own registration framework with it. What's wrong with the existing one? I think you should read more about the Django framework generally and go through the tutorial.

Looking at that traceback, the problem is in the line hashlib.new(str(random.random())).hexdigest()[:5]. (Get familiar with looking at tracebacks and working out what the issue is, you'll find you need to often when you make a mistake.)

help(hashlib.new) shows this:

__hash_new(name, string='')
    new(name, string='') - Return a new hashing object using the named algorithm;
    optionally initialized with a string.

The "named algorithm" should be md5, sha1, sha256, etc. (See help(hashlib) for the list, and also how you should use e.g. hashlib.md5() instead of hashlib.new('md5').)

haslib.new() expects a hashing algorithm name (e.g. "md5", "sha1" etc.) as the first parameter. You're passing in a random string.

when the password is saving at the time instead of hashlib i use sha cryptographic alog that works fine
