How to get started with Diogel

Secure browser extension for managing your Nostr identities without exposing your private keys to web applications.

Worried about exposing your nostr keys ? Diogel solves this.

NIP-07, which stands for "Nostr Implementation Proposal 07," is a standardised specification that enables web-based Nostr applications to securely interact with a user's account through a browser extension. It is exceptionally useful because it solves a critical security problem: instead of forcing users to manually copy and paste their sensitive private keys into every website or app they use—a practice that is highly vulnerable to phishing and malware—NIP-07 enables a dedicated browser extension, like the Diogel Browser Extension, to act as a secure vault.

When a web application needs to sign an event, like posting a message, it simply requests the action from the extension, which then handles the cryptographic signing process in a protected environment without ever exposing the user's keys to the website itself.

This creates a seamless and much safer user experience, by establishing a secure bridge between web applications and a user's private key management.

Diogel

Diogel is a privacy-focused Nostr account + signer browser extension designed to let you safely use Nostr apps without handing your private keys to websites.

It acts as a dedicated signer: Nostr web apps request signatures, and Diogel returns signatures—keys stay inside the extension.
