Question

I’m working with an application that requires sha1 encoding for certain form values.

The problem is that when I use the following

<?php echo(hash("sha1","par1=".$_POST['p1']."&par2=".$_POST['p2'])); ?>

It gives me a sha1 encoding of the actual string, while I want to get a sha1 encoding of the posted values, so in this example I want to get

<?php echo(hash("sha1","par1=firstvalue&par2=secondvalue")); ?>

How can I realize this? Is it actually that simple and am I thinking way to difficult?

Answer 1

That because it identifies that para1=some_value as string not para1 as variable and some_value string
To achieve what you want you should hash every variable alone

Or I suggest that you implement your own encoding algorithm
