     BN_new() allocates and initializes a BBBBIIIIGGGGNNNNUUUUMMMM structure.
     BN_init() initializes an existing uninitialized BBBBIIIIGGGGNNNNUUUUMMMM.

     BN_clear() is used to destroy sensitive data such as keys
     when they are no longer needed. It erases the memory used by
     aaaa and sets it to the value 0.

     BN_free() frees the components of the BBBBIIIIGGGGNNNNUUUUMMMM, and if it was
     created by BN_new(), also the structure itself.
     BN_clear_free() additionally overwrites the data before the
     memory is returned to the system.

     BN_new() returns a pointer to the BBBBIIIIGGGGNNNNUUUUMMMM. If the allocation
     fails, it returns NNNNUUUULLLLLLLL and sets an error code that can be
     obtained by ERR_get_error(3).

     BN_init(), BN_clear(), BN_free() and BN_clear_free() have no
     return values.

     BN_new(), BN_clear(), BN_free() and BN_clear_free() are
     available in all versions on SSLeay and OpenSSL.  BN_init()
     was added in SSLeay 0.9.1b.
