[CryptoAPI-devel] updates, bugs, and questions

[David B. <db...@du...>]

hey all,
no traffic for a while, so I thought i'd throw up an update on what's
going on, at least afaik.  Looks like we are almost ready for a release
save a couple of show stoppers.
- Apparently a data syncrhonization issue has cropped up with cryptoloop
and SMP machines, this is caused even when running SMP on a UP machine.=20
If anybody has experiences with this, or anything we can use to debug it
please post it.  Every little bit helps ;-)
- RC5 is still broken, not sure that it will be fixed before the next
release, it is currently disabled in the source code.
- hvr added a cryptoapi version macro in crypto.h
#define CRYPTO_API_VERSION_CODE 0x000100
is the current status.
- I've been workign on rewriting DES, and there is about 10 more lines
of code that i need for the key schedule and I am done.  It is currently
1/2 the size of the current implementation and MUCH more readable.  I am
also working on an assembly implementation on the side in ppc, hopefully
that will be done as well.
On another note, i'm having trouble grasping specific bit manipulations
in C :-( If anybody can help me out, or point me towards some helpful
links i would *really* appriciate it as I am kind of kludging along here
;-)

Finally, some interesting benchmarks i did quicly on my G4 867:
