Add "init" command to control ENGINE
initialization.
Call ENGINE_finish on initialized ENGINEs on exit.
Reorder shutdown in apps.c: modules should be shut
down first.
Add test private key loader to openssl ENGINE: this
just loads a private key in PEM format.
Fix print format for dh length parameter.
ENGINE redevelopment. The idea had been that "-1" could be used as a
special "ask me later" 'nid' rather than specifying supported cipher and
digest 'nid's up front. However the idea turned out to be pretty broken.
testing. Because of the recent changes (see crypto/engine/README), the
"openssl" ENGINE is no longer needed nor is it loaded automatically or by
ENGINE_load_builtin_engines(). So a explicit ENGINE_load_openssl() call is
required by applications or a modification to eng_all.c before this ENGINE
will be used. This change will send output to stderr as/when its
implementations are used.
ENGINE_TABLE-based stuff - as described in crypto/engine/README.
Associated miscellaneous changes;
- the previous cipher/digest hooks that hardwired directly to EVP's
OBJ_NAME-based storage have been backed out. New cipher/digest support
has been constructed and will be committed shortly.
- each implementation defines its own ENGINE_load_<name> function now.
- the "openssl" ENGINE isn't needed or loaded any more.
- core (not algorithm or class specific) ENGINE code has been split into
multiple files to increase readability and decrease linker bloat.
- ENGINE_cpy() has been removed as it wasn't really a good idea in the
first place and now, because of registration issues, can't be
meaningfully defined any more.
- BN_MOD_EXP[_CRT] support is removed as per the README.
- a bug in enginetest.c has been fixed.
NB: This commit almost certainly breaks compilation until subsequent
changes are committed.
