So that's what this does. This makes our salt.

We would just go through and say Obama go to the hashtable and hash Obama and make sure the value associated with it is 1.

That would be in its own file that has a functions related to art.

Mail functions

It takes a username and a password and an optional parameter for salt, and then returns the salt, the hash version of the name, password, and salt.

'Very,' said Alice ' where's the Duchess?'

Notice this time there is no user in the welcome. That's because it set a cookie.

There's a whole Udacity course on how to do testing.

So the way they work, first of all, is, as we said, they basically hash, the concatenation of the password and the salt.

The hash is a 32 character hexadecimal number.

Alice gave a little scream of laughter.

'Hush!

Grass? Hash? Coke?

If we double the number of buckets, the average lookup time is decreasing significantly.

So it takes a name and a password and the value in the database, and it makes sure the hash from the database matches the new hash created based on what the user entered in.

Only 1 10th of your keys get redistributed.

The way the Python dictionary is implemented, there's just one flat list.

And then we apply the hash function, oops, let me write it like this.

stored

Now, remember, we don't actually store passwords in the database, we just store hash of the password.

Another function I've added is this method called register, which takes a name, a password, and and e mail, and creates a new user object.

Certificate import hash successful created.

So the question is how does the range relate to this?

Those polls are fixed.

Calculates the MD5 hash of the specified filename using the RSA Data Security, Inc. MD5 Message Digest Algorithm

If a hash is not listed here, but is listed by mhash as supported, you can safely assume that this documentation is outdated.

So let's see how that works.

And if I were to, on this page, modify this cookie, change it to user id 5, which is what we had before, and I were to reload this page, we get redirected to the signup page, because the value in that cookie doesn't match the hash in that cookie, therefore is invalid, and we get bounced to the signup page.

And when you do a hashtable lookup you learned this in CS 101 we hash this value, we find it in the hashtable, and then we return the key or we return the value.

location.

If the name and password entered in match the password hash, from the object with that name in the database, we return the user.

Let's say we have a hash table with only 2 buckets.

It's going to be consistent. now, traditional traditional hash functions have been used in computer science for quite some time, and they're used in many computing applications.

And it's a very subtle notation.

Certificate import hash could not created.

Certificate import passphrase could not be removed.

Cisco certificate import cert found at current path.

First of all, as before they use a salt, a public, random value that's fixed forever.

I've installed this edit this cookie extension in Chrome, which is really handy for this sort of thing, to let me view a cookie, and we can see we have a cookie named userlD.

A set is a subset of itself, every member of a set is also a member of itself, so it's a subset of itself.

One of the more complicated things you do when you're writing web apps is all this kind of cookie and hashing and all that manipulation, but you can also start doing some really clever things.

And what do I mean by iterating it? So, well, we take the password and the salt.

If you're using consistent hashing, a key might hash to this space on a circle.

And we put them inside of one input to the hash function.

Right. Module hashing.
