1.5.6.4 to either PHP 7.2 or 7.3 SOLVED

Currently working with php 5.6 using opencart 1.5.6.4 But I NEED TO CHANGE TO PHP 7.2 OR 7.3 but keep getting blank screen when I change my opencart 1.5.6.4 to either PHP 7.2 or 7.3.

I have tried various Changes to encryption.php codes as follows:

<?php
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);
}
}


Also ----------------------------------------------------------------------------------------------------------------------------------------------------------

<?php
final class Encryption {
private $key;

public function __construct($key) {
$this->key = $key;
}

public function encrypt($value) {
if (function_exists('sodium_crypto_secretbox')) {
$nonce = random_bytes(SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);

return strtr(base64_encode($nonce . sodium_crypto_secretbox($value, $nonce, hash('sha256', $this->key, true))), '+/=', '-_,');
} else {
return strtr(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, hash('sha256', $this->key, true), $value, MCRYPT_MODE_ECB)), '+/=', '-_,');
}
}

public function decrypt($value) {
if (function_exists('sodium_crypto_secretbox')) {
$raw_value = base64_decode(strtr($value, '-_,', '+/='));

$nonce = substr($raw_value, 0, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);

return trim(sodium_crypto_secretbox_open(substr($raw_value, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES), $nonce, hash('sha256', $this->key, true)));
} else {
return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, hash('sha256', $this->key, true), base64_decode(strtr($value, '-_,', '+/=')), MCRYPT_MODE_ECB));
}
}
}
?>

But no joy, can anyone help, it would be appreciated !! Am I missing something else I need to do?

Did you switch to mysqli already ?
And try this one:

Hi thanks for your reply:

How do I switch from mysql to mysqli in opencart?
Do I need to change to mysqli?
My Server Database Type MySQL (Standard)
Plus tried your code and the same result, just blank white screen for website ON PHP 7.2

Regards

Do I need to change to mysqli?

Yes, mysql is no longer existing + valid on modern Servers.
In both config.php Files, change: TO: and that's it.
And if it still does not work, you have to remove your VqMods,
except for the vqmod_opencart.xml itself, to find out,
if one of them plays some role, to eventually keep your Site
from working.
HOWEVER, better download the latest v.1.5.6.5_rc Version first,
and use this one instead of yours, it only contains about 25 fixes,
to fix problems, found after the v.1.5.6.4 was released, but everything
else is still the same Code as 1.5.6.4 !Just overwrite all existing OC Files
on the Server with the new Code, exept for the Shop config.php
files, it should not do any harm. (If you never manually modified OC Source! )

And you also need to use the PHP-7 encryption.php file, as placed
above, to make it work with PHP7.2x at least. (I don't know about PHP 7.3 ,
since it is not available yet on my Server! But PHP 7.2x will stay for a while,
so, I would not care about 7.3 too much already anyway ! )

WOW Thank you so much, took over a week of trying everything.

I changed my config file to define('DB_DRIVER', 'mysqli');
I Changes to encryption.php code to the one you gave me!

But I still got the same plain white web page!

So I uninstalled all my VqMods, except for the vqmod_opencart.xml itself.

WORKS PERFECT on PHP 7.2!!!!!!!!

Thank you so much Ernie!

Good for you! Just find out now, which-one it was, and tell us about it,
I so far only found a 'file-manager' tool, able to 'handle' file and pics,
but unable to further work with php7, but it's always good to know, if
other Mods might keep the Baby from doing it's Job.

Hey, I want to do same thing, but I have OC 1.5.2.1. I followed all the steps and I no longer get ERROR 500 on PHP7, but instead I get white page with message saying "Error: Could not load database file mysqli!"
any ideas?
Just to make it clear what I've done:
I have OC 1.5.2.1 on PHP5
I moved it to new server with PHP7
I edited encryption.php in /system/library folder (copied the code from above)
Then I edited /admin/config.php and config.php (in shop root) and added the "i" at end of "mysql"
I tried removing vqmods too, but no luck.

EDIT: I figured it's because i'm missing the actual mysqli.php file as OC 1.5.2.1 doesn't even have it, I tried copying it from OC2 and renaming mysql.php to mysqli.php, but both result in either error 500 or just white blank page. I tried loading both /store/ and /store/admin. With one combination I get error 500 on front and blank page on admin. I really want to get my current one working. I already tried upgrading and it gives error 500 after upgrade.

Any ideas? thanks.

Copy mysqli.php (system/database) from 1.5.6.4 to your 1.5.2.1 (same path)

yeah I tried that, error 500 on shop front and blank page on /admin/
EDIT: I tried upgrading to 1.5.6.4, but it gives me ERROR 500 on admin panel after trying to login.
I suspect some extensions are giving me issues, but I can't exactly disable them if I can't even login.

EDIT2: has anyone tried installing 1.5.6.4 on PHP7 with the encryption.php mod? It's not working for me, I get the first license page (which seems bit broken) and when I click "continue" at bottom, then nothing happens. It seem to be just "refreshing" the page and nothing else happens.
I assume it's not possible to install one using this method?
I'm 99% sure that my old site's database has some entries that are causing the issue, I found some, but it's impossible to tell if it doesn't give me specific errors. I had some permission issues too, but again it's impossible to fix if I can't even see the errors.

I've done it a few times successfully. Most of that was probably down to luck.

Because you need to replace this code from install/index.php
With a new one And for debug, I gave already an url on your other topic. To add this code in index.php after <?php
Also you don't need admin acces to disable extensions/modules. You can do that from database.
