#include <openssl/x509.h>
X509 *X509_new(void);
void X509_free(X509 *a);
=head1 DESCRIPTION
The X509 ASN1 allocation routines, allocate and free an
X509 structure, which represents an X509 certificate.
X509_new() allocates and initializes a X509 structure.
X509_free() frees up the B<X509> structure B<a>.
=head1 RETURN VALUES
If the allocation fails, X509_new() returns B<NULL> and sets an error
code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
Otherwise it returns a pointer to the newly allocated structure.
X509_free() returns no value.
