Kask

Kask is a multi-master replicated opaque key-value data store.

On Dependency Management
The libraries an application depends on are as much a part of the final product as the code we write ourselves, and yet it is all too common for us to choose them indiscriminately, retrieve them via untrusted sources, and treat them (and the entire graph of transitive dependencies) as black-boxes. Often this pattern is deeply ingrained in our tools and the culture surrounding them. As Kask's raison d'etre is session storage, a use-case demanding of both security and robustness, greater rigor was needed.

Debian is a Linux distribution founded in 1996, with a long-standing reputation for quality control. Software that is packaged for Debian has been carefully curated. Packagers ensure that an active and response upstream exists, but accept responsibility for the duration of a release if an upstream becomes unwilling or unable to address issues. Care is taken to select the most appropriate version for release, and its transitive dependencies are satisfied by dependent relationships with other packages. Changes to a package during a stable release are made only on an as-needed basis (crippling bugs, security vulnerabilities, etc), and are as minimally invasive as possible. Additionally, PGP encryption is utilized to establish a strong chain of trust between the developers who upload packages, and the machines where they are ultimately installed.

Kask's code dependencies are sourced entirely from what is available in Debian (Stretch/9.8 at the time of writing).
