LockettePro is a block-protection plugin based on Lockette (https://github.com/Acru/Lockette), the code base is entirely re-written. It is 100% compatable with original Lockette, and the plugin behaviors are also 100% same.
This repo is a maintained fork of NyaaCat's LockettePro (https://github.com/NyaaCat/LockettePro).
