Pentagraph
Overview
Pentagraph is a Vue app for performing PGP encryption and decryption without trusting a server. Keys are loaded directly into the browser and stay there - nothing is ever transmitted or stored remotely. All operations happen locally using the Web Crypto API.
The typical use case is quick, one-off encrypted message exchange where you want the convenience of a web UI without handing your private key to a third-party service.
Limitations
Because keys are held in browser memory rather than persistent storage, they will be lost when the tab is closed or the browser clears its cache. Pentagraph is suited to short sessions, not long-term key management.
