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 registering 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_algorithms() are syn-
       onyms 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 initial-
       ization 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 initializa-
       tion, 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.
