📘

Signing opaque binary data is not supported.

For security reasons, this API only supports signing human-readable UTF-8 strings. It is not intended for signing opaque binary data since then it can be used to sign an arbitrary hash, which means it can be used to sign transactions, or any other data, making it a dangerous phishing risk.

Use transaction signing for signing transaction data or typed data signing for signing generic data objects.
