Keeping data encrypted and secure is becoming more and more common with website projects. This requirement can come up in complicated applications as well as simple blogs collecting visitor data. There aren’t a lot of default options for WordPress-powered sites to handle encryption. A lot of the time, for things like SSL certificates, you rely on your web hosting provider. For more complicated tasks, you might need custom code written to encrypt and process data. Thankfully, the WordPress community has stepped up with plugins. Take a look at our list of some useful WordPress encryption plugins you can use on your current or future client projects for data security.
