Function Documentation

   void RAND_add (const void * indata, size_t size, double entropi)
       Seed that random number generator. Secret material can securely be feed
       into the function, they will never be returned.

       Parameters:
           indata the input data.
           size size of in data.
           entropi entropi in data.

   int RAND_bytes (void * outdata, size_t size)
       Get a random block from the random generator, can be used for key
       material.

       Parameters:
           outdata random data
           size length random data

       Returns:
           1 on success, 0 on failure.

   void RAND_cleanup (void)
       Reset and free memory used by the random generator.

   const char* RAND_file_name (char * filename, size_t size)
       Return the default random state filename for a user to use for
       RAND_load_file(), and RAND_write_file().

       Parameters:
           filename buffer to hold file name.
           size size of buffer filename.

       Returns:
           the buffer filename or NULL on failure.

   const RAND_METHOD* RAND_get_rand_method (void)
       Get the default random method.

   int RAND_load_file (const char * filename, size_t size)
       Load a a file and feed it into RAND_seed().

       Parameters:
           filename name of file to read.
           size minimum size to read.

   int RAND_pseudo_bytes (void * outdata, size_t size)
       Get a random block from the random generator, should NOT be used for
       key material.

       Parameters:
           outdata random data
           size length random data

       Returns:
           1 on success, 0 on failure.

   void RAND_seed (const void * indata, size_t size)
       Seed that random number generator. Secret material can securely be feed
       into the function, they will never be returned.

       Parameters:
           indata seed data
           size length seed data

   int RAND_set_rand_engine (ENGINE * engine)
       Set the default random method from engine.

       Parameters:
           engine use engine, if NULL is passed it, old method and engine is
           cleared.

       Returns:
           1 on success, 0 on failure.

   int RAND_set_rand_method (const RAND_METHOD * meth)
       Set the default random method.

       Parameters:
           meth set the new default method.

       Returns:
           1 on success.

   int RAND_status (void)
       Return status of the random generator

       Returns:
           1 if the random generator can deliver random data.

   int RAND_write_file (const char * filename)
       Write of random numbers to a file to store for later initiation with
       RAND_load_file().

       Parameters:
           filename name of file to write.

       Returns:
           1 on success and non-one on failure.
