`window.nostr` capability for web browsers
------------------------------------------
`draft` `optional` `author:fiatjaf`
The `window.nostr` object may be made available by web browsers or extensions and websites or web-apps may make use of it after checking its availability.
That object must define the following methods:
```
async window.nostr.getPublicKey(): string // returns a public key as hex
async window.nostr.signEvent(event: Event): Event // takes an event object and returns it with the `sig`
async window.nostr.getRelays(): { [url: string]: {read: boolean, write: boolean} } // returns a map of relay urls to relay policies
async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext+iv as specified in nip-04
async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext+iv as specified in nip-04

- [nos2x](https://github.com/fiatjaf/nos2x) is available as a Chromium extension that provides such capabilities.
- [Alby](https://getalby.com) is a Bitcoin extension that also provides a compatible `window.nostr`.
