While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=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>.
|
|
|
|
=head1 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 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 EXAMPLE
|
|
|
|
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.
