SSL_LIBRARY_INIT(3) Library Functions Manual SSL_LIBRARY_INIT(3)

SSL_library_init, OpenSSL_add_ssl_algorithms, SSLeay_add_ssl_algorithmsinitialize SSL library by registering algorithms

#include <openssl/ssl.h>




() registers the available SSL/TLS ciphers and digests.

() and () are synonyms for SSL_library_init() and are implemented as macros.

() must be called before any other action takes place. SSL_library_init() is not reentrant.

() adds ciphers and digests used directly and indirectly by SSL/TLS.

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

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 */
