SSL_library_init(3)          OpenSSL          SSL_library_init(3)



NAME

       SSL_library_init, OpenSSL_add_ssl_algorithms,
       SSLeay_add_ssl_algorithms - initialize SSL library by reg-
       istering algorithms


LIBRARY

       libcrypto, -lcrypto


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_algo-
       rithms() 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 impor-
       tant initialization is the seeding of the PRNG (Pseudo
       Random Number Generator), which has to be performed sepa-
       rately.


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.
