Mcrypt ile Şifreleme Sınıfı

I recently tried running Magento v1 on PHP7.1 and ran into the following error:

Function mcyrpt_module_open() is deprecated

I did some Googling to see if this has happened to other people, and sure enough, it has. Cadence Labs has a post that provides an easy workaround.

However, I take issue with the fact that this doesn't actually get past the usage of mcrypt. MCrypt is abandoned entirely in later versions of PHP and I need to make sure my clients and I are running long term solutions.

The better way to resolve this is to copy the Varien_Crypt_Mcrypt class to the local code folder at /app/code/local/Varien/Crypt/Mcrypt.php. Then refactor the class to use OpenSSL encrypt/decrypt functions instead. If you want, you can just download the code I wrote for this and drop it in your install.

Warning: I have not tested this for backwards compatibility and I have only used this successfully with the AES-256-ECB cipher.

There are some methods in the code that attempt to translate old Mcrypt constants (ciphers and modes) to their OpenSSL alternatives, but you should do as much testing as possible before putting this in production.

<?php $dmcryptText = “dummy”; $key = “foobar”; $size = mcrypt_get_iv_size(MCRYPT_BLOWFISH,MCRYPT_MODE_ECB);

$iv = mcrypt_create_iv($size); //Take care

$m = mcrypt_ecb(MCRYPT_BLOWFISH, $key, $dmcryptText, MCRYPT_DECRYPT, $iv); var_dump($m);

When 20 requests of this script are sent to the server in parallel, we can find the response time of Apache server increases rapidly. The reason for the…

Mcrypt, içerisinde bazı metin şifreleme algoritmalarını barındıran bir php eklentisidir. Gerek Laravel gibi framework’ler, gerekse magento gibi içerik yönetim sistemleri bu eklentiye ihtiyaç duyar.

“mcrypt php extension required” hatasını almanızın birden fazla sebebi olabilir. Şöyle ki; Localhost üzerinde çalışıyorsanız MAMP, XAMP gibi paketlerde aslında bu eklenti mevcuttur. Ancak MacOs işletim…

Install PHP Mcrypt on CentOS

Install PHP Mcrypt on CentOS

Overview

The PHP module “Mcrypt” provides encryption and decryption using algorithms such as DES, TripleDES and Blowfish. You can read more about it on the official PHP Mcrypt page.

This is required by eCommerce systems such as Magento, however it’s not part of the standard RHEL / CentOS packaging.

CentOS 6 and 6.5 allow you to install PHP-mCrypt easily right after installing CentOS. The reason mCrypt is removed by default from version  7 is still unknown, but we’re going to show you how to re-enable it.

The php-mcrypt package is available (for CentOS, Scientific Linux, and Oracle Linux administrators) from the RPMforge repository and from the EPEL repository.

  How to install mcrypt ?

First, add the repository. For example, to add EPEL:

# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Then, install the php-mcrypt module:

# yum install php-mcrypt

If you see this —-> its OK :)

yum install php-mcrypt.x86_64
