Summary​

This document introduces the High-Level Specification of the Stronghold.

Logical System Design​

Low Level​

A Stronghold is composed of several interacting systems at a low level:

  1. Snapshot - box-encrypted file-based persistence layer
  2. Vault - a write and use protected, path-based system for storing and using secrets like private keys
  3. Store - a read/write key:value storage system for dynamic data
  4. Cache - an in-memory abstraction for vault and store
  5. Runtime - memory protection system for secrets

High Level​

At the high level, Stronghold provides an official client for interfacing with a Stronghold snapshot and its records.
