Those are block ciphers, not stream ciphers.

Dear DragonFlyBSD bugs,


Today I updated the L15 algorithm, available from:

http://www.leopard.uk.com/L15

The update is to the KSA (Key Scheduling Algorithm).

Perhaps DragonFlyBSD should consider updating their version,
as used for /dev/urandom ?

---

Also, I posted a bug report (some months ago now, I suspect),
which had to do with IBAA (as used for /dev/random), and specifically
relating to warming up the CSPRNG just before output in:

read_random()

As opposed to doing the warm-up after seeding the CSPRNG,
which unless I am mistaken, is what DragonFlyBSD does at the
moment.

I think there might also be one other update to L15 which I
mentioned on bugs at dragonflybsd.org quite a while ago, which
I don't think was met with a response. That was to do with the
STATEINDEX_CARRY change that I made to L15.

---

In any case I am always happy to discuss these issues by E-mail ...


PS Good luck with the new 3.8.0 Release !!
