X509_LOAD_HTTP(3ossl) OpenSSL X509_LOAD_HTTP(3ossl)
NAME
X509_load_http, X509_http_nbio, X509_CRL_load_http, X509_CRL_http_nbio
- certificate and CRL loading functions
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 OPENSSL_API_COMPAT with a suitable version
value, see openssl_user_macros(7):
#define X509_http_nbio(rctx, pcert)
#define X509_CRL_http_nbio(rctx, pcrl)
DESCRIPTION
X509_load_http(3) and X509_CRL_load_http() loads a certificate or a CRL,
respectively, in ASN.1 format using HTTP from the given url.
Maximum size of the HTTP response is 100 kB for certificates and 32 MB
for CRLs and hard coded in the functions.
If bio is given and rbio is NULL then this BIO is used instead of an
internal one for connecting, writing the request, and reading the
response. If both bio and rbio are given (which may be memory BIOs,
for instance) then no explicit connection is attempted, bio is used for
writing the request, and rbio for reading the response.
If the 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.
RETURN VALUES
On success the function yield the loaded value, else NULL. Error
conditions include connection/transfer timeout, parse errors, etc.
