openssl_x509_check_private_key — Checks if a private key corresponds to a certificate
$certificate, OpenSSLAsymmetricKey|OpenSSLCertificate|array|string $private_key): bool
Checks whether the given private_key is the private key
that corresponds to certificate.
The function does not check if private_key is indeed a private key or not.
It merely compares the public materials (e.g. exponent and modulus of an RSA key)
and/or key parameters (e.g. EC params of an EC key) of a key pair.
This means, for example, that a public key could be given for private_key
and the function may return true.
certificateThe certificate.
private_keyThe private key.
Returns true if private_key is the private key that
corresponds to certificate, or false otherwise.
