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 SSL/TLS 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.  SSL_library_init() is not reentrant.

WARNING

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

EXAMPLES

       A typical TLS/SSL application will start with the library initialization, and provide readable error messages.

	SSL_load_error_strings();		 /* readable error messages */
	SSL_library_init();			 /* initialize library */

RETURN VALUES

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

NOTES

       OpenSSL 0.9.8o and 1.0.0a and later added SHA2 algorithms to SSL_library_init().  Applications which need to use SHA2 in earlier versions
       of OpenSSL should call OpenSSL_add_all_algorithms() as well.
