Nostr Signer Extension

This allows you to sign Nostr events on web-apps without having to give them your keys.

It provides a window.nostr object which has the following methods:

async window.nostr.getPublicKey(): string // returns your public key as hex
async window.nostr.signEvent(event): Event // returns the full event object signed
async window.nostr.getRelays(): { [url: string]: RelayPolicy } // returns a map of relays
async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext+iv as specified in nip04
async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext+iv as specified in nip04
