NAME

SSL_CTX_config, SSL_config - configure SSL_CTX or SSL structure

SYNOPSIS

#include <openssl/ssl.h>

int SSL_CTX_config(SSL_CTX *ctx, const char *name);
int SSL_config(SSL *s, const char *name);

DESCRIPTION

The functions SSL_CTX_config() and SSL_config() configure an SSL_CTX or SSL structure using the configuration name.

NOTES

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 RETURN VALUES

SSL_CTX_config() and SSL_config() return 1 for success or 0 if an error occurred.

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

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;
}

SSL_CONF_cmd(3), HISTORY

SSL_CTX_config() and SSL_config() were first added to OpenSSL 1.1.0
