Plebeian Signer

Nostr Identity Manager & Signer

Plebeian Signer is a browser extension for managing multiple Nostr identities and for signing events on web apps without having to give them your keys.

It implements these mandatory NIP-07 methods:

async window.nostr.getPublicKey(): string
async window.nostr.signEvent(event: { created_at: number, kind: number, tags: string[][], content: string }): Event

It also implements these optional methods:

async window.nostr.getRelays(): { [url: string]: {read: boolean, write: boolean} }
async window.nostr.nip04.encrypt(pubkey, plaintext): string
async window.nostr.nip04.decrypt(pubkey, ciphertext): string
async window.nostr.nip44.encrypt(pubkey, plaintext): string
async window.nostr.nip44.decrypt(pubkey, ciphertext): string

The repository is configured as monorepo to hold the extensions for Chrome and Firefox.
