X509_CHECK_PRIVATE... DragonFly Library Functions Manual X509_CHECK_PRIVATE...

NAME
     X509_check_private_key, X509_REQ_check_private_key -- compare public key
     components

SYNOPSIS
     #include <openssl/x509.h>

     int
     X509_check_private_key(const X509 *x, const EVP_PKEY *k);

     int
     X509_REQ_check_private_key(X509_REQ *x, EVP_PKEY *k);

DESCRIPTION
     These functions are seriously misnamed.  X509_check_private_key() com-
     pares the public key components (e.g. exponent and modulus of an RSA key)
     and parameters (e.g. EC params of an EC key) of k with the corresponding
     properties of x.  Despite the name, it neither checks whether k contains
     private key components at all, nor, if any are present, whether they are
     consistent with the public key components.

     X509_REQ_check_private_key() is equivalent to X509_check_private_key()
     except that it compares to the public key contained in a certificate
     request.

RETURN VALUES
     These functions return 1 if the public key components and parameters
     match, or 0 if they do not or if an error occurs.	On error or mismatch,
     a reason code can be obtained using ERR_get_error(3).
