Sending a NIP-17 DM builds a kind-1059 gift wrap, which needs a fresh ephemeral
keypair. generateEphemeralKeypair() hex-encodes the generated secret with
bytesToHex — but bytesToHex was never imported in client.js, so the call threw
ReferenceError. The try/catch swallowed it into privateKey="", keygen returned
null, and every NIP-17 send failed with "We couldn't create secure wrapper keys
for NIP-17 delivery." (nip17-keygen-failed). The seal (kind 13) signed fine
because it uses the active signer; only the ephemeral keygen was broken. Build
and lint don't parse JS, so the missing import wasn't caught.
- Add bytesToHex to the canonical js/utils/hex.js and import it in client.js.
- Add tests/nip17-send-gift-wrap.test.mjs: forces the NIP-17 path (useNip17 +
relay hints, nip44-capable signer) and asserts a kind-1059 gift wrap is
published. Reverting the import reproduces the exact nip17-keygen-failed error;
the existing DM tests only covered the legacy kind-4/NIP-04 path (they delete
nip44Encrypt), so this path had no coverage.
