Nkosec Encode, 2 side encode. change alphabet to numeric or back numeric to alphabet.
- focused on alphanumeric, use a simple logic str_replace.
- this logic is made, when I make a challenge for a friend in a detective game.
<?php
include('nk26.php');
nk26_encode('hello there');
result : 961515180115961136
nk26_encode_safe('Hello There'); // hello there(lowercase)
result : 961515180115961136
nk26_decode('961515180115961136');
result : hello there
