SSL_LIBRARY_INIT(3) Library Functions Manual SSL_LIBRARY_INIT(3)

NAME

SSL_library_init, OpenSSL_add_ssl_algorithms, SSLeay_add_ssl_algorithmsinitialize 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 */
