check_ca(), to resolve constness issue. check_ca() is called from the
purpose checkers instead of X509_check_ca(), since the stuff done by
the latter (except for calling check_ca()) is also done by
X509_check_purpose().
CA setting in each certificate on the chain is correct. As a side-
effect always do the following basic checks on extensions, not just
when there's an associated purpose to the check:
- if there is an unhandled critical extension (unless the user has
chosen to ignore this fault)
- if the path length has been exceeded (if one is set at all)
- that certain extensions fit the associated purpose (if one has been
given)
Use BUF_strlcat() instead of strcat().
Use BIO_snprintf() instead of sprintf().
In some cases, keep better track of buffer lengths.
This is part of a large change submitted by Markus Friedl <markus@openbsd.org>
structures for fields that are not OPTIONAL.
However in the AUTHORITY_INFO_ACCESS case
the 'location' field was set to NULL in
the old code.
So in 0.9.7+ we should free up the field before
overwriting it in v2i_AUTHORITY_INFO_ACCESS.

Split private key PEM and normal PEM handling. Private key
handling needs to link in stuff like PKCS#8.
Relocate the ASN1 *_dup() functions, to the relevant ASN1
modules using new macro IMPLEMENT_ASN1_DUP_FUNCTION. Previously
these were all in crypto/x509/x_all.c along with every ASN1
BIO/fp function which linked in *every* ASN1 function if
a single dup was used.
Move the authority key id ASN1 structure to a separate file.
This is used in the X509 routines and its previous location
linked in all the v3 extension code.
Also move ASN1_tag2bit to avoid linking in a_bytes.c which
is now largely obsolete.
So far under Linux stripped binary with single PEM_read_X509
is now 238K compared to 380K before these changes.
Add new extension functions which work with NCONF.
Tidy up extension config routines and remove redundant code.
Fix NCONF_get_number().
Todo: more testing of apps to see they still work...
the 'ca' utility. This can now be extensively
customised in the configuration file and handles
multibyte strings and extensions properly.
This is required when extensions copying from
certificate requests is supported: the user
must be able to view the extensions before
allowing a certificate to be issued.
change the way ASN1 modules are exported.
Still needs a bit of work for example the hack which a
dummy function prototype to avoid compilers warning about
multiple ;s.
and make all files the depend on it include it without prefixing it
with openssl/.
This means that all Makefiles will have $(TOP) as one of the include
directories.
