Since 4.0.0, we have added an extra way of storing your API details.
Your settings are stored in the WP database, which means that an SQL exploit may result in access to your settings key data. While such an exploit also has access to the rest of the database as those settings are unencrypted, it does leave the potential for an exploit. Other payment gateway plugins implement the same procedure when saving the API credentials, but we’d like to offer something different to protect your data.
You can now define the credentials on your website. This means that the settings are no longer stored in the database. Should a hacker gain access to the database, the settings are not visible to them.
0 = SHA-1
1 = SHA-256
2 = SHA-512
We recommend that SHA-512 is set, this is more secure, if you do decide to use SHA-512 then you would define it like this:
define( ‘secure_ePDQ_SHA_method’, ‘2’ );
Before proceeding, please create a backup of your site as you will be editing your theme/website files as a preventive measure if you have accidentally deleted any code. You can ask your hosting provider to backup your site for you.
You would need to use the code below and replace the required credentials for your ePDQ account below:
// This stops anyone from editing the plugin files within the WP admin
define(‘DISALLOW_FILE_EDIT’ , true);
define( ‘secure_ePDQ_PSPID’, ‘#replace with PSPID for account#’ );
define( ‘secure_ePDQ_SHA_in’, ‘#replace with SHA in for account#’ );
define( ‘secure_ePDQ_SHA_out’, ‘#replace with SHA out for account#’ );
define( ‘secure_ePDQ_SHA_method‘, ‘#replace with SHA method for account#’ );
Once you have replaced it with the correct information, copy and paste the code on your theme’s functions.php file.
The quickest way to add these would be to add them to your theme’s functions.php file from your:
WordPress dashboard > Appearance > Theme Editor > click the functions.php from the file selection.
After that, kindly click the Update File button for the changes to be applied.
We recommend that you add the above code into the wp-config.php file via FTP.
Alternatively, you can also use a third-party plugin like the Code Snippets by Code Snippets Pro plugin to add the code instead of manually adding it on your theme’s function.php file.
