How to format a PHP-OpenSSL signature to be verifiable with elliptic?

[gitgoodboy]

How to verify something like this?

PHP

$privkey = "-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIElP6IpLbE3Jd7KdBjlHtgtJfcZ94/OEkCoIsl/iV8q8oAcGBSuBBAAK
oUQDQgAECQ5QVzipmVe7SUco3rzOgvaO+f70wN5jVVHDK2bSVY1OV3OCW0UZmSjU
az/p1DNMYv9tcjPUuPwf+eCtxXSepg==
-----END EC PRIVATE KEY-----
";

openssl_sign(bin2hex($data), $sign, $privkey, OPENSSL_ALGO_SHA256);
$sign = base64_encode($sign);

This always returns false:

Typescript

const data: string = json_response["data"];
const sign64: string = json_response["sign64"];

let EC = require('elliptic').ec;
let ec = new EC('secp256k1');
let key = ec.keyFromPublic("04090e505738a99957bb494728debcce82f68ef9fef4c0de635551c32b66d2558d4e5773825b45199928d46b3fe9d4334c62ff6d7233d4b8fc1ff9e0adc5749ea6", 'hex');

let sign = Buffer.from(sign64, "base64").toString("hex");
let datahex = Buffer.from(data, "utf-8").toString("hex");

console.log(key.verify(datahex, sign));

I suggested a change to REAME.md. You must hash your data manually.
