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);
int
OpenSSL_add_ssl_algorithms(void);
int
SSLeay_add_ssl_algorithms(void);
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() and are
implemented as macros.
SSL_library_init()
must be called before any other action takes place.
SSL_library_init() is not reentrant.
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.
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 */
