NAME
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.
