=head1 NAME
X509_check_private_key, X509_REQ_check_private_key - check the consistency
of a private key with the public key in an X509 certificate or certificate
request
=head1 SYNOPSIS
#include <openssl/x509.h>
int X509_check_private_key(X509 *x, EVP_PKEY *k);
int X509_REQ_check_private_key(X509_REQ *x, EVP_PKEY *k);
=head1 DESCRIPTION
X509_check_private_key() function checks the consistency of private
key B<k> with the public key in B<x>.
X509_REQ_check_private_key() is equivalent to X509_check_private_key()
except that B<x> represents a certificate request of structure B<X509_REQ>.
=head1 RETURN VALUE
X509_check_private_key() and X509_REQ_check_private_key() return 1 if
the keys match each other, and 0 if not.
If the key is invalid or an error occurred, the reason code can be
obtained using L<ERR_get_error(3)>.
=head1 BUGS
The B<check_private_key> functions don't check if B<k> itself 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. So if you pass a public key to these functions in B<k>, it will
return success.
