Is there a chart somewhere that shows what version of PHP is required/supported for which version of opencart?

Depending on the OC Version used, it works up to PHP v.7.4.x (as tested so far),
and for older OC Versions, to achieve that, one possibly needs to
use a system/library/encryption.php file like this one:

Code: Select all

final class Encryption {
	private $cipher = 'aes-256-ctr';
	private $digest = 'sha256';
	private $key;
	public function __construct($key) {
		$this->key = $key;

	public function encrypt($value) {
		$key       = openssl_digest($this->key, $this->digest, true);
		$iv_length = openssl_cipher_iv_length($this->cipher);
		$iv        = openssl_random_pseudo_bytes($iv_length);
		return base64_encode($iv . openssl_encrypt($value, $this->cipher, $key, OPENSSL_RAW_DATA, $iv));
	public function decrypt($value) {
		$key       = openssl_digest($this->key, $this->digest, true);
		$iv_length = openssl_cipher_iv_length($this->cipher);
		$value     = base64_decode($value);
		$iv        = substr($value, 0, $iv_length);
		$value     = substr($value, $iv_length);
		return openssl_decrypt($value, $this->cipher, $key, OPENSSL_RAW_DATA, $iv);
In later OC Versions, that php end ?> is no longer required.
Other encryption.php files are available in the OC Extension Section as well.
Usually, nothing else is required, to make PHP v.7.x work on OpenCart.
But a specific List on this does not exist.

Older versions do not have any fixes for vulnerabilities to jquery, bootstrap, etc. It is best to use one of the newer versions and PHP 7.2+

Take a close look at our domain pricing. It's cheaper than most of the 'big name' registrars.

I am using an old version of PHp and want to check which version of opencart would support it.
How to check the same?
