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()
DESCRIPTIONSSL_library_init() registers the available ciphers and digests.
OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms()
are synonyms for SSL_library_init().
NOTESSSL_library_init() must be called before any other action
takes place. WARNINGSSL_library_init() only registers ciphers. Another important
initialization is the seeding of the PRNG (Pseudo Random Number
Generator), which has to be performed separately. EXAMPLESA typical TLS/SSL application will start with the library
initialization, will provide readable error messages and will seed
the PRNG.
RETURN VALUESSSL_library_init() always returns "1", so it is safe to discard
the return value. SEE ALSOssl(3) , SSL_load_error_strings(3) , RAND_add(3)
