=head1 NAME
|
|
|
|
SSL_CTX_config, SSL_config - configure SSL_CTX or SSL structure
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int SSL_CTX_config(SSL_CTX *ctx, const char *name);
|
|
int SSL_config(SSL *s, const char *name);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The functions SSL_CTX_config() and SSL_config() configure an B<SSL_CTX> or
|
|
B<SSL> structure using the configuration B<name>.
|
|
|
|
By calling SSL_CTX_config() or SSL_config() an application can perform many
|
|
complex tasks based on the contents of the configuration file: greatly
|
|
simplifying application configuration code. A degree of future proofing
|
|
can also be achieved: an application can support configuration features
|
|
in newer versions of OpenSSL automatically.
|
|
|
|
A configuration file must have been previously loaded, for example using
|
|
CONF_modules_load_file(). See L<config(5)> for details of the configuration
|
|
file syntax.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_CTX_config() and SSL_config() return 1 for success or 0 if an error
|
|
occurred.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
If the file "config.cnf" contains the following:
|
|
|
|
testapp = test_sect
|
|
|
|
[test_sect]
|
|
# list of configuration modules
|
|
|
|
ssl_conf = ssl_sect
|
|
|
|
[ssl_sect]
|
|
server = server_section
|
|
|
|
[server_section]
|
|
RSA.Certificate = server-rsa.pem
|
|
ECDSA.Certificate = server-ecdsa.pem
|
|
Ciphers = ALL:!RC4
|
|
|
|
An application could call:
|
|
|
|
if (CONF_modules_load_file("config.cnf", "testapp", 0) <= 0) {
|
|
fprintf(stderr, "Error processing config file\n");
|
|
goto err;
|
|
}
|
|
|
|
ctx = SSL_CTX_new(TLS_server_method());
|
|
|
|
if (SSL_CTX_config(ctx, "server") == 0) {
|
|
fprintf(stderr, "Error configuring server.\n");
|
|
goto err;
|
|
}
|
|
|
|
In this example two certificates and the cipher list are configured without
|
|
the need for any additional application code.
