An extremely important and justified question! Plugins created by me, in which personal or confidential data is entered, always contain a method for securely storing this data in encrypted form. Let me briefly describe this in more detail. Preliminary remark This is not about creating backups. The topic of this article is a description of how plugins developed by me handle data worthy of protection. As the website operator, you are responsible for backing up your website's data. Basic ideas There are various methods of implementing encryption. The German Federal Ministry for Security has provided an article on this here: https://www.bsi.bund.de/DE/Themen/Verbraucherinnen-und-Verbraucher/Informationen-und-Empfehlungen/Cyber-Sicherheitsempfehlungen/Daten-sichern-verschluesseln-und-loeschen/Datenverschluesselung/datenverschluesselung_node.html They recommend the use of the Advanced Encryption Standard (AES), which according to current knowledge is the way to go. However, this alone is not enough, as you should not only think about the encryption method but also about where the necessary key is stored. Use in my plugins Each of my plugins that require this therefore contains a component that provides AES encryption based on PHP's own functions. In hosting where OpenSSL is available, this is also used. If OpenSSL is not available, Sodium is used. The encrypted data is stored in WordPress' own database. Keys are required for both methods. These are neither stored in the files of my plugins nor in the project's database, but in the project's wp-config.php. If the wp-config.php cannot be written to, a must-use plugin is created that contains the key. This means that the encrypted data and the key for decryption are logically separated. According to my research, this corresponds to the ISO/IEC 27002 standard. Advantages of this method Unlike other solutions, the user of the plugin does not have to worry about this protection. My plugins do this fully automatically in the background. This means that there is literally no effort required to set it up. Disadvantages Of course, there are also disadvantages. If the key is lost, the encrypted data can no longer be decrypted. The website operator should therefore make sure to include the wp-config.php and/or the must-use plugin in his data backup. This is the only way to restore the key used and access your data in the event of unexpected problems with one of the files. Interested? The code for the above is included as a GPL license in the respective free plugins.
