CrystalKeep

A comprehensive solution for encrypted data storage.

Running

To get up and running, clone this repository, and open a terminal in the directory containing the pom.xml file. Run the following maven command:

mvn javafx:run

You can also use the javafx-maven-plugin to generate an executable using mvn javafx:jlink.

Design

CrystalKeep makes use of Shards as the most basic form of encrypted data storage. A shard is a single data item, like login credentials, an image, or some text. One or more shards are stored in a Cluster, which is essentially a collection of shards (and possibly nested clusters). Top-level clusters (not nested inside another) can be encrypted and saved with a secret key passphrase.

With this approach, the user minimizes the amount of data that is accessible to an attacker in the event that the attacker gets access to the system while the contents of a cluster are unencrypted in memory, since only one cluster may be actively open at a time.

Furthermore, by removing a dependency on the host filesystem for encryption of, for example, files or directories, this solution is guaranteed to be equally secure across all platforms that it can run on.
