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
