Failed to receive encrypted url variable

This is where I send my link variable to another form

<td>
    <?php echo $this->tag->linkTo(array("spm_contacto/delete/" .$this->crypt->encryptBase64($spm_contacto->CONT_CODIGO), "<img src='" . $this->url->get("img/tolbar/Delete_32x32.png") . "'>Eliminar")); ?></td>

To which I test if sending values sent encrypted or not

<?php $prueba=$this->crypt->encryptBase64($spm_contacto->CONT_CODIGO);
echo $prueba;
echo $this->crypt->decryptBase64($prueba);
?>

This is the result SqVg4xBmCQIkHFT656DBiToN0Yz8k4w+wuQQfn+BtGa1bsyee3UsRJoFIX+rL1L2Zrhgl3XiDXGuEr5c4QT+Ew==0401014717 zqxExWmJDAIU1k7M3adUO/1C5U9ywUbp5ULlxwdYlQm1KO4REUvB9P9V1Rzden+LI4SiNMll5fWpdD7FZO4tyQ==0803784016 Ssau2QyuBBgc8eQa1cVl505zHH4wmwbOhz34pSZuDnDxOGx3DX1ztPrjdf9fTJh5knTWZQeCjr5ZZ6ShSLbBbw==0908868128 qHDZldcucpDezWYvXJBvQwTwf6eWHpZFRwqXFbMZahN/m6q6imhUKI36THEgoUdIT7UCIhGhp5o8cW3LnRjRvw==1713516779 b+eGob7Lk6DO5gFK8nBjIRXs/l4GvuR/BBjqifJV0MxwgqByQMwOZ82rSLfqx972k9BIU5b46k3SihgSjtKv1A==1716931553 Q5BTRerh8RQ25s74szSjtYJqWRp8tviO264+pyWdGf3EatO29L2JVobyVHN4zLE+7krYoxgDSAcB4un9ncl+YQ==1720566247 QZKy1oPBpukuR5SKdPOD5xs2sPVs5bMt1CLRxrzwYmo0bbjvFAiAe6aroWkFObTmoS/8jlilX6h1JL5smR8ejA==1721241899 jHV/9SJTDsUa19u7D9GH3SS4m+chAYk1mRNyfWmg+pacR27rpL3d4vEuP2+Th6vBnbukJ2/rgdzK29sqthPOmw==1723995336 yBbE/lPatFc68gplLvTdb/VQp0ehAAwVZnEi/FQSKcmDAQxd/Y6ue11OeZrW6k1w5aVu2y59HhizbGf9C9nQRg==1724130693 2s7ylO4QeNSPaVaBnF8gFJmRGq+Zu5bSyFlg0gHuMEUxzPGvZcShIxR8an5CUjtlDuTojZQrpi0x59GtFTMq9g==1724908197

In my controller that receives the variable is so

echo $CONT_CODIGO;
echo $this->crypt->decryptBase64(trim($CONT_CODIGO));
$spm_contacto = SpmContacto::findFirstByCONT_CODIGO($this->crypt->decryptBase64($CONT_CODIGO));
        if (!$spm_contacto) {
            $this->flash->error("spm_contacto was not found");

            return $this->dispatcher->forward(array(
                "controller" => "spm_contacto",
                "action" => "index"
            ));
        }

But the result is

use phalcon filter to remove symbol from base64 encrypt https://docs.phalconphp.com/en/latest/reference/filter.html

<?php
use Phalcon\Filter;

$filter = new Filter();

echo $CONT_CODIGO;
$var =  $filter->sanitize($this->crypt->decryptBase64(trim($CONT_CODIGO)),"alphanum");
echo $var;
$spm_contacto = SpmContacto::findFirstByCONT_CODIGO($var);
        if (!$spm_contacto) {
            $this->flash->error("spm_contacto was not found");

            return $this->dispatcher->forward(array(
                "controller" => "spm_contacto",
                "action" => "index"

This I have in my file no use my key services

$di->set('crypt', function () {

$crypt = new Crypt();

// Set a global encryption key
$crypt->setKey('abc');

return $crypt;
}, true);

I was try like your code but it didn't work , here is my code it 's ok and I'm using it

in my service

<?php
$di->set('crypt', function () {
    $crypt = new Phalcon\Crypt();
    return $crypt;
});

in my controller

<?php
    public function testAction(){
        $key = 'yourcryptkey';
        $text = 'test';
        $encrypt = $this->crypt->encryptBase64($text, $key);
        echo ' encrypt : ' . $encrypt . '<br/>';
        $decrypt =  $this->filter->sanitize($this->crypt->decryptBase64($encrypt,$key),'alphanum'); 
        echo 'decrypt : ' . $decrypt . '<br/>;
    }

hope it will work with you too.

Encryption and decryption at the same time if it works, the problem is that I want to send a variable to encrypt and decrypt URL in another form, that's when the problem occurred

    }

    public function typeAction(){
        $key = 'test';
        $text = 'Type';
        $encrypted = $this->crypt->encryptBase64($text, $key);

DatatableController.php

<?php
use \DataTables\DataTable;
use Phalcon\Mvc\View;

class DatatableController extends ControllerBase
{
    public function initialize() {
        parent::initialize();
        $this->view->disableLevel(View::LEVEL_MAIN_LAYOUT);
    }

    public function getAction($tb=''){

        $this->view->disable();
        if($this->request->isAjax() == TRUE){
            $encrypted    = $this->request->getPost('instance');
            $table        = $this->filter->sanitize($this->crypt->decryptBase64($encrypted,'test'),'alphanum'); 
            echo $table;
        }
    }
}

when you echo this $instance variable it will show 'Type' sorry for my bad english.
