getting the bottommost one. I hope I understood correctly how this
should be done. It seems to work when running evp_test in an
environment where it can't find openssl.cnf.
1. rnd_reference was a duplication of the work the the engine
framework does, and wasn't ever checked. Removed.
2. use the NO_ macros to disable appropriate algorithms.
3. Only implement the RNG stuff if AEPRAND is defined (default: not
defined, because the AEP people plan on having boards without it.
I'll see if I can device a more dynamic way of disabling this).
4. aep_finish() now closes all connections, and if that worked, does a
proper finalize.
5. proper AEP types are used to conform to the AEP definitions of
their own functions.
6. remake the use of thread locks. The use of CRYPTO_LOCK_DYNLOCK was
definitely inappropriate, and for random generator stuff, it's
better to use CRYPTO_LOCK_RAND.
Also, I applied certain changes that were provided by the AEP people.
Among others, BN_CTX_new() is not used to initialise a BN context
(this was never done before, and may have made things slower or not
working at all.
that were never part of the engine framework.
The aep and sureware implementations are taken directly from 0.9.6c
[engine] and have been modified to fit the newer engine framework and
to be possible to build shared libraries of.
The aep implementation has gone through quite a bunch of tests and is
cleaned up (there were some misunderstandings in it about how to use
locks).
The sureware hasn't been tested at all in this incarnation and is
basically a quick hack to get it to compile properly.
functions in ui_compat. This gave reason to rework that part more
thoroughly, so here are the changes made:
1. Add DES_read_password() and DES_read_2passwords() with the same
functionality as the corresponding old des_ functions, as a
convenience to the users.
2. Add UI_UTIL_read_pw_string() and UI_UTIL_read_pw() with the
functionality from des_read_pw_string() and des_read_pw(), again as
a concenience to the users.
3. Rename des_read_password(), des_read_2passwords(),
des_read_pw_string() and des_read_pw() by changing des_ to
_ossl_old_des_, and add the usual mapping macros.
4. Move the implementation of des_read_password() and
des_read_2passwords() to the des directory, since they are tightly
tied to DES anyway.
This change was inspired by a patch from Assar Westerlund <assar@sics.se>:
There are some functions that didn't get the kick-away-old-des-and-
replace-des-with-DES action. Here's a patch that adds DES_ and des_
(in des_old.h) versions of des_read_pw_string et al. This patch
includes some of the first des_old.h semi-colon macro fixes that I've
already sent.
This patch makes the macros in des_old.h actually pretend to be
functions.
There's no reason not to define _ossl_old_crypt when using
PERL5/FreeBSD/darwin/Next, since it makes using crypt and including
des.h break. Here's a trivial patch.
This patch fixes some of the typos used in macro names in des_old.h
and the number of arguments for some of them.
