openssl_x509_check_private_key

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

openssl_x509_check_private_keyChecks if a private key corresponds to a certificate

说明

bool openssl_x509_check_private_key ( mixed $cert , mixed $key )

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.

参数

cert

The certificate.

key

The private key.

返回值

Returns TRUE if key is the private key that corresponds to cert, or FALSE otherwise.

This function will return FALSE if the private key requires a pass phrase.
