yet tighter, and also put some heat on the rest of the library by
insisting (correctly) that compare callbacks used in stacks are prototyped
with "const" parameters. This has led to a depth-first explosion of
compiler warnings in the code where 1 constification has led to 3 or 4
more. Fortunately these have all been resolved to completion and the code
seems cleaner as a result - in particular many of the _cmp() functions
should have been prototyped with "const"s, and now are. There was one
little problem however;
X509_cmp() should by rights compare "const X509 *" pointers, and it is now
declared as such. However, it's internal workings can involve
recalculating hash values and extensions if they have not already been
setup. Someone with a more intricate understanding of the flow control of
X509 might be able to tighten this up, but for now - this seemed the
obvious place to stop the "depth-first" constification of the code by
using an evil cast (they have migrated all the way here from safestack.h).
Fortunately, this is the only place in the code where this was required
to complete these type-safety changes, and it's reasonably clear and
commented, and seemed the least unacceptable of the options. Trying to
take the constification further ends up exploding out considerably, and
indeed leads directly into generalised ASN functions which are not likely
to cooperate well with this.
"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order. Thusly fixed.
aka X509_LOOKUP_load_file(...) is always 0 or 1, not the counter
returned from the recently introduced function X509_load_cert_crl_file.
X509_STORE_load_locations expects X509_LOOKUP_load_file to return 1 on
success, and possibly there's other software that relies on this too.
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.
that can automatically determine the type of a DER encoded
"traditional" format private key and change some of the
d2i functions to use it instead of requiring the application
to work out the key type.
yet.
Add a function X509_STORE_CTX_purpose_inherit() which implements the logic
of "inheriting" purpose and trust from a parent structure and using a default:
this will be used in the SSL code and possibly future S/MIME.
Partial documentation of the 'verify' utility. Still need to document how all
the extension checking works and the various error messages.
in a table. Doesn't do too much yet.
Make the -<digestname> options in 'x509' affect all relevant
options.
Change the name of the 'notrust' options to 'reject' as this
causes less confusion and is a better description of the
effect.
A few constification changes.
Extend the X509_PURPOSE structure to include shortnames for purposed and default
trust ids.
Still need some extendable trust checking code and integration with the SSL and
S/MIME code.
plain not working :-(
Also fix some memory leaks in the new X509_NAME code.
Fix so new app_rand code doesn't crash 'x509' and move #include so it compiles
under Win32.
