Crate signer_nostr 

Nostr transaction signer built on BIP-340 Schnorr over secp256k1.

Implements the signing side of the Nostr protocol (NIP-01) with NIP-19 bech32 key encoding (nsec for private keys, npub for x-only public keys).

Key derivation from a mnemonic is handled by kobe-nostr (NIP-06) — this crate is signing only.

Examples

use signer_nostr::{Sign as _, Signer};

// NIP-06 test vector 1.
let signer = Signer::from_hex(
    "7f7ff03d123792d6ac594bfa67bf6d0c0ab55b6b1fdb6249303fe861f1ccba9a",
)
.unwrap();
assert!(signer.address().starts_with("npub1"));

// Sign a NIP-01 event id (32-byte SHA-256 of the canonical serialization).
let event_id = [0u8; 32];
let out = signer.sign_hash(&event_id).unwrap();
assert_eq!(out.to_bytes().len(), 64); // BIP-340 Schnorr
