SSL_CTX_CONFIG - Online Linux Manual PageSection : 3ossl
Updated : 2022-03-15
Source : 3.0.2
Note : OpenSSL
NAMESSL_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);
DESCRIPTIONThe functions SSL_CTX_config() and SSL_config() configure an SSL_CTX or ​SSL structure using the configuration 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 config (5) for details of the configuration file syntax.
RETURN VALUES​SSL_CTX_config() and SSL_config() return 1 for success or 0 if an error occurred.
EXAMPLESIf 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.

HISTORYThe SSL_CTX_config() and SSL_config() functions were added in OpenSSL 1.1.0.
