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. SSL_library_init() is not reentrant.

WARNING

SSL_library_init() adds ciphers and digests used directly and indirectly by

EXAMPLES

A typical application will start with the library initialization, and provide readable error messages.

 SSL_load_error_strings();                /* readable error messages */
 SSL_library_init();                      /* initialize library */

RETURN VALUES

SSL_library_init() always returns ``1'', so it is safe to discard the return value.

NOTES

OpenSSL 0.9.8o and 1.0.0a and later added algorithms to SSL_library_init(). Applications which need to use in earlier versions of OpenSSL should call OpenSSL_add_all_algorithms() as well.
