SSL_library_init, OpenSSL_add_ssl_algorithms,
SSLeay_add_ssl_algorithms - initialize SSL library by
registering algorithms
SYNOPSIS
#include <openssl/ssl.h>
int SSL_library_init(void);
#define OpenSSL_add_ssl_algorithms() SSL_library_init()
#define SSLeay_add_ssl_algorithms() SSL_library_init()
DESCRIPTION
SSL_library_init() registers the available ciphers and
digests.
OpenSSL_add_ssl_algorithms() and
SSLeay_add_ssl_algorithms() are synonyms for
SSL_library_init().
NOTES
SSL_library_init() must be called before any other action
takes place.
WARNING
SSL_library_init() only registers ciphers. Another
important initialization is the seeding of the PRNG
(Pseudo Random Number Generator), which has to be
performed separately.
EXAMPLES
A typical TLS/SSL application will start with the library
initialization, will provide readable error messages and
will seed the PRNG.
SSL_load_error_strings(); /* readable error messages */
SSL_library_init(); /* initialize library */
actions_to_seed_PRNG();
RETURN VALUES
SSL_library_init() always returns "1", so it is safe to
discard the return value.
