 RAND_file_name() generates a default path for the random seed
 file. B<buf> points to a buffer of size B<num> in which to store the
-filename. The seed file is $RANDFILE, if that environment variable is
-set, $HOME/.rand otherwise. If $HOME is not set either, or B<num> is
+filename. The seed file is $RANDFILE if that environment variable is
+set, $HOME/.rnd otherwise. If $HOME is not set either, or B<num> is
 too small for the path name, an error occurs.

+RAND_load_file() reads a number of bytes from file B<filename> and

 RAND_write_file() writes a number of random bytes (currently 1024) to
-file B<filename> which can be used to initialze the PRNG by calling
+file B<filename> which can be used to initialize the PRNG by calling
