NAME

       SSL_library_init, OpenSSL_add_ssl_algorithms - initialize SSL library by registering
       algorithms

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_library_init(void);

        int OpenSSL_add_ssl_algorithms(void);

DESCRIPTION

       SSL_library_init() registers the available SSL/TLS ciphers and digests.

       OpenSSL_add_ssl_algorithms() is a synonym for SSL_library_init() and is implemented as a
       macro.

NOTES

       SSL_library_init() must be called before any other action takes place.  SSL_library_init()
       is not reentrant.

WARNING

       SSL_library_init() adds ciphers and digests used directly and indirectly by SSL/TLS.

RETURN VALUES

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

SEE ALSO

       ssl(7), RAND_add(3)

HISTORY

       The SSL_library_init() and OpenSSL_add_ssl_algorithms() functions were deprecated in
       OpenSSL 1.1.0 by OPENSSL_init_ssl().
