SHA384 Nonce auth pattern — bitfinex.
Signs "AUTH{nonce}" (nonce = timestamp_ms) with HMAC-SHA384 hex and
builds a flat auth frame — no nested args.
Example Frame (bitfinex)
%{
"event" => "auth",
"apiKey" => "api_key",
"authSig" => "hex_signature",
"authNonce" => 1699999999999,
"authPayload" => "AUTH1699999999999"
}Config
| Key | Default | Purpose |
|---|---|---|
:event_value | "auth" | Top-level event field |
:timestamp_ms_override | (unset) | Test-only — freezes the nonce |
