+ * ```ts
+ * async function sign_msg (logger: sk.Logger) : Promise<void> {
+ *     let acc_pubkey : string = pv_address;
+ *     // @ts-ignore value property exists because i say so
+ *     let msg_text   : string = document.getElementById('message-text').value;
+ *     let signed_msg = await sk.msg_sign('sk-msg-sign-1', acc_pubkey, msg_text, sk.TIMEOUT_DEF_MSG_SIGN_MS, 'message signing took too long', logger);
