=head1 DESCRIPTION

The loaded B<X509_INFO> object's can contain a CRL, a certificate and a
corresponding private key.

PEM_X509_INFO_read_ex() loads the B<X509_INFO> objects from a file I<fp>.
The library context I<libctx> and property query <propq> are used for fetching
algorithms from providers.

PEM_X509_INFO_read_bio_ex loads the B<X509_INFO> objects using a bio
I<bp>. The library context I<libctx> and property query <propq> are used for
fetching algorithms from providers.


=head1 RETURN VALUES

PEM_X509_INFO_read_ex() and PEM_X509_INFO_read_bio_ex() return
a stack of B<X509_INFO> objects or NULL on failure.
