About
NostrKey is a Safari extension for macOS and iOS that manages your Nostr identities and signs events on your behalf — your private keys never touch the websites you visit.
Features:
• NIP-07 signing — works with any Nostr web app
• NIP-46 nsecBunker — remote signing, your key never leaves the bunker
• NIP-44 encryption — modern ChaCha20-Poly1305 messaging
• Encrypted document vault — zero-knowledge storage on Nostr relays
• API key vault — encrypted secret storage
• Master password — keys encrypted at rest with auto-lock
• Multi-profile support — manage multiple Nostr identities
• Per-site permissions — control which sites can request signatures
• iCloud sync — profiles, settings, and vault data sync across your Apple devices via storage.sync (Safari 16+, user-toggleable)
Your keys. Your control. No data collection. No tracking. Fully open source.
