openssl_x509_check_private_key
(PHP 4 >= 4.2.0, PHP 5, PHP 7)
openssl_x509_check_private_key — Checks if a private key corresponds to a certificate
Description
Checks whether the given key is the private key
that corresponds to cert.
Warning
The function does not check if 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 key
and the function may return TRUE.
Parameters
cert- The certificate.
key- The private key.
Return Values
Returns TRUE if key is the private key that
corresponds to cert, or FALSE otherwise.
