Aurora Vault solves the problem of securely storing and verifying the integrity of sensitive data, such as system configurations and API responses, without relying on a third-party service to manage keys or store plaintext data.
Aurora Vault is a tool that provides client-side encryption, append-only proof history, and CLI-first workflows without key custody. It encrypts files on the user's machine before they are uploaded to the server, which stores opaque ciphertext. Each upload receives a signed Ed25519 receipt and is added to an append-only hash-chain ledger. The tool can read from stdin, allowing users to preserve output from various commands, such as terraform and kubectl. It can be used to create a verifiable record of system configurations over time.
