In an early draft of the new PRNG, before I decided to get rid of random_byte() and replace it with random_read(), it was important after generating a hash-worth of PRNG output to buffer it so as to return it a byte at a time. So the PRNG data structure itself had to keep a hash-sized buffer of pending output, and be able to return the next byte from it on every random_byte() call. But when random_read() came in, there was no need to do that any more, because at the end of a read, the generator is re-seeded and the remains of any generated data is deliberately thrown away. So the pending_output buffer has no need to live in the persistent prng object; it can be relegated to a local variable inside random_read (and a couple of other functions that used the same buffer since it was conveniently there). A side effect of this is that we're no longer yielding the bytes of each hash in reverse order, because only the previous silly code structure made it convenient. Fortunately, of course, nothing is depending on that - except the cryptsuite tests, which I've updated. |
