My computing teachers are funny sometimes, today they refused to believe that one way encryption exists!

It's not Mozilla Firebird it's that bloody awful Norton Personal Firewall  pop up add blocker.

They keep changing the code it injects into every page so everytime I try and filter it out they change it again.

Is there any chance you could post me the code it injects so I can try filtering it.

It looks like:-


<script language="javascript"><!--

window.open = SymRealWinOpen;

//-->

</script>

this what your looking for

<script language="JavaScript">
<!--

function SymError()
{
  return true;
}

window.onerror = SymError;

//-->
</script>

but i think that's part of the forum's code... doesn't do anything to my posts

Here it is:

<script language="JavaScript">
<!--

function SymError()
{
return true;
}

window.onerror = SymError;

var SymRealWinOpen = window.open;

function SymWinOpen(url, name, attributes)
{
return (new Object());
}

window.open = SymWinOpen;

//-->
</script>

Ohhhh ok then, forgive my arrogance.  So whats the difference between a hash and an encryption?

encryption can be decrypted a hash is 1 way and cannot be encrypted.

Of course there is one-way-encryption, Hash is just a commonly known expression for one-way-encryption thus it being the same. You can also call it irreversible encryption.

I.e. if you get the ASCII code of a character and times it by something that changes, e.g. current second on server time then your not gooing to be able to decypt it. Obviously it doesnt use server time though because then it would change every time its hashed.
