Charset Storage Locks is a Charset module which adds Keys, Keyrings and Locks.
Inspired by the mod BetterStorage, this module allows you to lock containers with a Lock. Said Lock is crafted based on a Key, and only that Key - or a duplicate - may be used to open it.
Locks and Keys block player interaction and, if a special option is enabled in CharsetPatches, extraction and insertion by machines. (This option is not enabled by default as it is rather invasive. It should be fine to enable it on the server side only, however.)
To make life easier, Keys can be carried around in Keyrings, and - if Baubles is installed - put on as a Bauble so you don't have to hold the key every time you try to open a locked inventory. Locks and Keys may also be dyed to tell them apart easier!
This version of the mod requires CharsetLib!
