There was recently an instance where a user was confused by the deprecation warnings in the docs. They believed the warning applied to the immediately preceding function declarations, when it fact it applied to the following function declarations. https://mta.openssl.org/pipermail/openssl-users/2021-December/014665.html We clarify the wording to make it clear that the warning applies to the following functions.

=head1 NAME
|
|
|
|
X509_load_http,
|
|
X509_http_nbio,
|
|
X509_CRL_load_http,
|
|
X509_CRL_http_nbio
|
|
- certificate and CRL loading functions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
X509 *X509_load_http(const char *url, BIO *bio, BIO *rbio, int timeout);
|
|
X509_CRL *X509_CRL_load_http(const char *url, BIO *bio, BIO *rbio, int timeout);
|
|
|
|
The following macros have been deprecated since OpenSSL 3.0, and can be
|
|
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
|
see L<openssl_user_macros(7)>:
|
|
|
|
#define X509_http_nbio(rctx, pcert)
|
|
#define X509_CRL_http_nbio(rctx, pcrl)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_load_http() and X509_CRL_load_http() loads a certificate or a CRL,
|
|
respectively, in ASN.1 format using HTTP from the given B<url>.
|
|
|
|
If B<bio> is given and B<rbio> is NULL then this BIO is used instead of an
|
|
internal one for connecting, writing the request, and reading the response.
|
|
If both B<bio> and B<rbio> are given (which may be memory BIOs, for instance)
|
|
then no explicit connection is attempted,
|
|
B<bio> is used for writing the request, and B<rbio> for reading the response.
|
|
|
|
If the B<timeout> parameter is > 0 this indicates the maximum number of seconds
|
|
to wait until the transfer is complete.
|
|
A value of 0 enables waiting indefinitely,
|
|
while a value < 0 immediately leads to a timeout condition.
|
|
|
|
X509_http_nbio() and X509_CRL_http_nbio() are macros for backward compatibility
|
|
that have the same effect as the functions above but with infinite timeout
|
|
and without the possibility to specify custom BIOs.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
On success the function yield the loaded value, else NULL.
|
|
Error conditions include connection/transfer timeout, parse errors, etc.
