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

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.
