php[architect]: Security Corner: PHP, meet Libsodium
On the php[architect] site they've posted an article that appeared in their December 2017 issue, an article that introduces Libsodium (by Eric Mann), a new addition to PHP's "security toolbelt" for encryption.
In the article he covers the basics of the Sodium library (that libsodium is built on top of) and what makes it different from other encryption methods. He also talks about what's been done to support it on pre-PHP 7.2 versions including the sodium_compat polyfill library and the PECL extension for PHP 7.0+. Example code is included showing how to use this new functionality via native functions once support for it has been compiled in.
