=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.
