Cryptographic technology in Craft Providers

Craft Providers uses cryptographic technologies to communicate with processes running on the host system. It does not directly implement its own cryptography, but it does depend on external libraries to do so.

Communication with local processes

Craft Providers uses the Requests library to communicate over Unix sockets with the local snap daemon (snapd). These requests are used to fetch information about required software. If the software is missing, Craft Providers will install it through snapd. This is done by querying the snapd API with URLs built dynamically and sanitized by urllib.
