deviates from the "standard" 64 bits of feedback that all other
algorithms are using. Therefore, let's redo certain EVP macros to
accept different amounts of feedback bits for these modes.
Also, change e_aes.c to provide all usually available modes for AES.

replacement implementation). This change makes sure the correct
implementation's "init()" handler is used rather than assuming 'type'.
crypto/rijndael. Additionally, I applied the AES integration patch
from Stephen Sprunk <stephen@sprunk.org> and fiddled it to work
properly with the normal EVP constructs (and incidently work the same
way as all other symmetric cipher implementations).
This results in an API that looks a lot like the rest of the OpenSSL
cipher suite.
libdes (which is still used out there) or other des implementations,
the OpenSSL DES functions are renamed to begin with DES_ instead of
des_. Compatibility routines are provided and declared by including
openssl/des_old.h. Those declarations are the same as were in des.h
when the OpenSSL project started, which is exactly how libdes looked
at that time, and hopefully still looks today.
The compatibility functions will be removed in some future release, at
the latest in version 1.0.
such cases, a flush should *not* attempt to finalise the encoding, as
the EVP_ENCODE_CTX structure will only be filled with garbage. For
the same reason, do the same check when a wpending is performed.
not implemented. (Bug reported by Martin Szotkowski)
This also changes the non-"_ex" versions to defer directly to
EVP_CipherInit_ex() rather than EVP_CipherInit() to avoid an unecessary
level of indirection.
See crypto/engine/README for details.
- 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.
ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.
Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.
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.

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

like des_read_password and friends (backward compatibility functions
using this new API are provided). The purpose is to remove prompting
functions from the DES code section as well as provide for prompting
through dialog boxes in a window system and the like.
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.
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.
records, EVP_EncodeUpdate() may misbehave. This happens when there's
a record boundary between the two ending b64 equal signs, which makes
EVP_EncodeUpdate think there has been more than one EOF, and therefore
add an extra NUL at the end of the output buffer. This fix corrects
that problem.
size) through the base64 filter, b64_write() messes up it's parameters
in such a way that instead of writing correct base64 output, the first
4 characters of that output is repeated over and over. This fix
corrects that problem.
could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.
This is mostly a work around for the old VC++ problem
that it treats func() as func(void).
Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.
The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.
Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)
Also, "make update" has added some missing functions to libeay.num,
updated the TABLE for the alpha changes, and updated thousands of
dependancies that have changed from recent commits.
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.
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
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.

Declare ciphers in terms of macros. This reduces

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.
enhance and tidy up the EVP interface.
This patch adds initial support for variable length ciphers
and changes S/MIME code to use this.
Some other library functions need modifying to support use
of modified cipher parameters.
Also need to change all the cipher functions that should
return error codes, but currenly don't.
And of course it needs extensive testing...
"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.
designed for that. This removes the potential error to mix data and
function pointers.
Please note that I'm a little unsure how incorrect calls to the old
ctrl functions should be handled, in som cases. I currently return 0
and that's it, but it may be more correct to generate a genuine error
in those cases.
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.
Never use des_set_key (it depends on the global variable des_check_key),
but usually des_set_key_unchecked.
Only destest.c bothered to look at the return values of des_set_key,
but it did not set des_check_key -- if it had done so,
most checks would have failed because of wrong parity and
because of weak keys.
in cryptlib.h (which is often included as "../cryptlib.h"), then the
question remains relative to which directory this is to be interpreted.
gcc went one further directory up, as intended; but makedepend thinks
differently, and so probably do some C compilers. So the ../ must go away;
thus e_os.h goes back into include/openssl (but I now use
#include "openssl/e_os.h" instead of <openssl/e_os.h> to make the point) --
and we have another huge bunch of dependency changes. Argh.
the secret key before we've encrypted it and using the right NID for RC2-64.
Add various arguments to the experimental programs 'dec' and 'enc' to make
testing less painful.
This stuff has now been tested against Netscape Messenger and it can encrypt
and decrypt S/MIME messages with RC2 (128, 64 and 40 bit) DES and triple DES.
Its still experimental though...
(meaning pointer to char) to des_cblock * (meaning pointer to
array with 8 char elements), which allows the compiler to
do more typechecking. (The changed argument types were of type
des_cblock * back in SSLeay, and a lot of ugly casts were
used then to turn them into pointers to elements; but it can be
done without those casts.)
Introduce new type const_des_cblock -- before, the pointers rather
than the elements pointed to were declared const, and for
some reason gcc did not complain about this (but some other
compilers did).
find the right RecipientInfo based on the recipient certificate (so would
fail a lot of the time) and fixup cipher structures to correctly (maybe)
modify the AlgorithmIdentifiers. Largely untested at present... this will be
fixed in due course. Well the stuff was broken to begin with so if its broken
now then you haven't lost anything :-)
to error code script: it can now find untranslatable function codes (usually
because the function is static and not defined in a header: occasionally because
of a typo...) and unreferenced function and reason codes. To see this try:
perl util/mkerr.pl -recurse -debug
Also fixed some typos in crypto/pkcs12 that this found :-)
Also tidy up some error calls that had to be all on one line: the old error
script couldn't find codes unless the call was all on one line.
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
consistent in the source tree and replaced `/bin/rm' by `rm'. Additonally
cleaned up the `make links' target: Remove unnecessary semicolons, subsequent
redundant removes, inline point.sh into mklink.sh to speed processing and no
longer clutter the display with confusing stuff. Instead only the actually
done links are displayed.
1. The already released version was 0.9.1c and not 0.9.1b
2. The next release should be 0.9.2 and not 0.9.1d, because
first the changes are already too large, second we should avoid any more
0.9.1x confusions and third, the Apache version semantics of
VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
.2 is already just a patchlevel and not major change).
