Encryption and Decryption – Base 64

Here is the Way to Encode And Decode Data

<form id=”form5″ name=”form5″ method=”post” action=””>
enter text
<input name=”data5″ type=”text” />
<input type=”submit” name=”Submit5″ value=”Encript” />
<input type=”submit” name=”Submit6″ value=”Decript” />
</form>
<?php
if(!isset($_POST[‘Submit5’])) {
}else {
$buffer = $_POST[‘data5’];
echo base64_url_encode($buffer);
}

if(!isset($_POST[‘Submit6’])) {
}else {
$buffer = $_POST[‘data5’];
echo base64_url_decode($buffer);
}

echo “<br/>”;

function base64_url_encode($input)
{
return strtr(base64_encode($input), ‘+/=’, ‘-_,’);
}
function base64_url_decode($input)
{
return base64_decode(strtr($input, ‘-_,’, ‘+/=’));
}
?>
