- it also removes openbsd_hw.c from the build (that functionality is
going to be available in the openbsd ENGINE in a upcoming commit)
- evp_test has had the extra initialisation added so it will use (if
possible) any ENGINEs supporting the algorithms required.
distinction (which does not work well because if CRYPTO_MDEBUG is
defined at library compile time, it is not necessarily defined at
application compile time; and memory debugging now can be reconfigured
at run-time anyway). To get the intended semantics, we could just use
the EVP_DigestInit_dbg unconditionally (which uses the caller's
__FILE__ and __LINE__ for memory leak debugging), but this would make
memory debugging inconsistent. Instead, callers can use
CRYPTO_push_info() to track down memory leaks.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
was a really bad idea. For example, the following:
#include <x509.h>
#include <bio.h>
#include <asn1.h>
would make sure that things like ASN1_UTCTIME_print() wasn't defined
unless you moved the inclusion of bio.h to above the inclusion of
x509.h. The reason is that x509.h includes asn1.h, and the
declaration of ASN1_UTCTIME_print() depended on the definition of
HEADER_BIO_H. That's what I call an obscure bug.
Instead, this change makes sure that whatever header files are needed
for the correct process of one header file are included automagically,
and that the definitions of, for example, BIO-related things are
dependent on the absence of the NO_{foo} macros. This is also
consistent with the way parts of OpenSSL can be excluded at will.
Change EVP_SealInit() and EVP_OpenInit() to
handle cipher parameters.
Make it possible to set RC2 and RC5 params.
Make RC2 ASN1 code use the effective key bits
and not the key length.
TODO: document how new API works.
Declare ciphers in terms of macros. This reduces
the amount of code and places each block cipher EVP
definition in a single file instead of being spread
over 4 files.
Change functions like EVP_EncryptUpdate() so they now return a
value. These normally have software only implementations
which cannot fail so this was acceptable. However ciphers
can be implemented in hardware and these could return errors.
