Re: heimdal and OpenSSL
Clearly I'm talking to a brick wall. This is my last message to you
on this subject. I'll post again to the list next week so that those
who have tuned out due to this inane discourse will have a chance to

Yes: without my patch, one cannot use OpenSSL in place of libdes.
With my patch, you can, as long as you have des_new_random_key. Or,
as I said, you can continue to use the included libdes.

No questions? This is where you got lost. My changes do not make
OpenSSL part of Heimdal, nor do they make Heimdal require OpenSSL.
THEY MERELY MAKE THE APIs COMPATIBLE.

This has nothing to do with me. I don't even know what this is about.

This corrects an abstraction error in otp_md.c: the typedef should
have been used instead of the underlying type.

This renames several API functions and one typedef.

This also has nothing to do with me, this is your futzing.

My changes do.

1) That applying the patches I posted to the list will not break
Heimdal on any platform.
2) That it will make it possible to build Heimdal with OpenSSL on
those platforms with appropriate support.

But it is. It is a prerequisite to supporting OpenSSL. I think they
are appropriate for all platforms -- certainly it won't harm anything
(with the exception that some applications might require recompiling
... but I don't know of the existence of any).
A complete solution apparently requires pulling rnd_keys.c out of
libdes as well for some platforms. Maybe this is what you are asking
me to do -- it's hard to tell.

That's fabulous, I'm so happy for you. Where are your patches? Did
they not involve renaming the libdes API functions under discussion?

Please show me the exact place where they do. I'm waiting.

You've brought OpenSSL into this again. OpenSSL is not on the table.
I did not suggest changing Heimdal to require OpenSSL -- in fact I
think that _you_ did.
Besides, if OpenSSL has a crappy PRNG on some platforms, that has
little to do with Heimdal. Supply your patches to the OpenSSL folks.
