Diogel

Diogel is a free, open-source browser extension for Chrome and Firefox designed to securely manage multiple Nostr identities and facilitate NIP-07 signing. The extension addresses the need for safer handling of private keys when interacting with Nostr-compatible applications, ensuring that private keys remain protected and never leave the extension environment. Diogel is intended for users who require a secure, streamlined way to manage personal, work, or anonymous Nostr profiles across different web applications.

Key features of Diogel include the ability to manage multiple identities in one place, easily switch between them, and either import existing keys or generate new ones. The extension maintains profile metadata such as display names and related information for each identity. Private keys are stored in an encrypted, password-protected vault on the user's device, with support for auto-locking after periods of inactivity to enhance security. Diogel ensures that only cryptographic signatures or approved responses are shared with websites, never the private keys themselves.

The extension provides granular permission controls, allowing users to review and approve signing requests by site and request type. Before approving any action, Diogel displays clear details about what a site is requesting, supporting informed consent and user control. Users can configure preferred read and write relays to tailor their Nostr experience according to their workflow and privacy needs.

Diogel is explicitly built to avoid unnecessary data collection, with no analytics enabled by default, no external key storage, and no third-party access to private keys. Its focus is on delivering secure NIP-07 signing for Nostr applications without additional tracking. The extension is suitable for privacy-conscious individuals who want to keep their Nostr identities separate, secure, and easy to use while maintaining full control over their signing permissions and private key security.
