This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. For more information about the manual page format, see the manual page for manpages(5). |
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 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.
