openssl_x509_check_private_key

Checks if a private key corresponds to a certificate

&reftitle.description; `bool` `openssl_x509_check_private_key` ``OpenSSLCertificate``string```certificate` ``OpenSSLAsymmetricKey``OpenSSLCertificate``array``string```private_key`

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;.

&reftitle.parameters;

`certificate`

- The certificate.

`private_key`

- The private key.

&reftitle.returnvalues;

Returns &true; if `private_key` is the private key that corresponds to `certificate`, or &false; otherwise.
