NAME    [Toc]    [Back]

       SSL_library_init, OpenSSL_add_ssl_algorithms,
       SSLeay_add_ssl_algorithms - initialize SSL library by registering
 algorithms

SYNOPSIS    [Toc]    [Back]

        #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    [Toc]    [Back]

       SSL_library_init() registers the available ciphers and
       digests.

       OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algo-
       rithms() are synonyms for SSL_library_init().

NOTES    [Toc]    [Back]

       SSL_library_init() must be called before any other action
       takes place.

WARNING    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       SSL_library_init() always returns "1", so it is safe to
       discard the return value.
