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

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.
