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
  The SSL_library_init() function registers the available ciphers and
  digests.

  The OpenSSL_add_ssl_algorithms() and SSLeay_add_ssl_algorithms() functions
  are synonyms for the SSL_library_init() function.

NOTES
  The SSL_library_init() function must be called before any other action
  takes place.

RESTRICTIONS
  The SSL_library_init() function only registers ciphers.  Another important
  initialization is the seeding of the PRNG (Pseudo Random Number Generator),
  which has to be performed separately.

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

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();

SEE ALSO
  Functions: ssl(3), SSL_load_error_strings(3), RAND_add(3)
