验证PHP中的错误 - openssl_verify（）

Question

I am trying to verify signature via openssl_verify() function:

PHP code:

$signature = pack("H*", $ecdsa);
$verified = openssl_verify($data, $signature, $public_key, "sha256");

Error message:

error: error:0606C06E:digital envelope routines:EVP_VerifyFinal:wrong public key type

What means error message "wrong public key type"?
