Password and http 1

[petersJazz]

hi,

is there a simple way to encrypt a password given in a form so that it will be sent crypted to server where a php script will decrypt it?

Something like this?

You have to click on links to see what they have, petersJazz. BPRS's obviously underscored [red]this[/red] is a link to a webpage that has an answer to your question.

I personally use a one-way hash of the password for this kind of thing and store the hash in the database. That way no one will be able to retrieve the password, and matching the hashed value against the hashed value works the same as matching a decrypted password against a stored password.

Sorry, I missed the link. Your comment makes sence, thank you a lot. But now I have to find out how to do it. I have very limited experiance in client side programming, us to do everything on server.

Looks nice but it is very complicated and I have no idee how to implement it on a web page.

Here's a quick one that I've used for a number of years. I won't guarantee it can't be cracked or that it won't produce duplicate values.

function checklogin(onestring)
{
var mult=1, hnumber=0;
for (var si=0;si<onestring.length;si++)
  {
  var onenumber=onestring.charCodeAt(si) * mult;
  hnumber += onenumber;
  mult *= 3;
  }
return hnumber;
}

Encrypt the password when the form is submitted, put the value in a hidden input, and then the script on the server that processes the form will get the value.
