openssl_x509_check_private_key
Checks if a private key corresponds to a certificate
Description
bool openssl_x509_check_private_key(OpenSSLCertificatestring $certificate, #[\SensitiveParameter]OpenSSLAsymmetricKeyOpenSSLCertificatearraystring $private_key)
Warning
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.
Parameters
-
certificate
-
The certificate.
-
private_key
-
The private key.
Return Values
Returns true if private_key is the private key that
corresponds to certificate, or false otherwise.
