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 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 important initialization 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 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.
