Using Libsodium in PHP Projects

Using Libsodium in PHP Projects

A guide to using the libsodium PHP extension for modern, secure, and fast cryptography. Developers can now develop fast, secure, and reliable applications without needing to know what a stream cipher even is.

This e-book is intended for PHP developers with no prior cryptography experience. To that end, this ebook will not go too in-depth to the nature of the lower-level cryptography features that each libsodium feature uses. Towards the end of each chapter, a link will be provided to other resources that explain the finer details for readers that are interested.

After reading this brief electronic manual, you should…

  • Know what libsodium is, what features it has, and how to install it (both the library and the PHP extension from PECL).
  • Generally understand which cryptography tool to use for a specific scenario.
  • Be capable of writing production-quality code that uses libsodium.

Chapters breakdown
