ajax jquery hash part 1

I keep recording videos too long, so there is a part 1 and part 2. This video shows you how to use jquery to make a simple ajax call to a php script that determines the md5 hash of what your typing. The trick is that is live as you type. I also go over some CSS centering, shortcuts and some CSS 3 things. Watch part 2 for the 2nd half.

I started to watch this video and I have a feeling there is some value here, however, I have no idea what it is - What is "hash"? what is "md5"? Who is this video targeted for?

@c532869 hash is a one way encryption key. md5 is just one of many mathematical algorithms for creating these encryptions.

So the use for this is with passwords. You never want to store a users password in raw format. Using hashes, you only store the encrypted password, and when a user tries to login you compare the encrypted password to the hash of what the user typed in. That way someone listening to the connections never sees the password and can't hack in.

could you maybe give us a download link for the 2 files

@optikalefxx But isn't that what H-T-T-P-S is for? My understanding is that a developer would use the H-T-T-P-S protocol to transmit sensitive information. This way, H-T-T-P-S handles the encryption relieving the developer of having to implement techniques such as the one you describe.
