This is a library for encrypting data with a key or password in PHP. It requires PHP 5.4 or newer. The current version is v2.0.0, which is expected to remain stable and supported by its authors with security and bugfixes until at least January 1st, 2019.
The library is a joint effort between Taylor Hornby and Scott Arciszewski as well as numerous open-source contributors.
What separates this library from other PHP encryption libraries is, firstly, that it is secure. The authors used to encounter insecure PHP encryption code on a daily basis, so they created this library to bring more security to the ecosystem. Secondly, this library is "difficult to misuse." Like libsodium, its API is designed to be easy to use in a secure way and hard to use in an insecure way.
