continue with symmetric decryption process to avoid leaking timing
information to an attacker.
Thanks to Ivan Nestlerode <inestlerode@us.ibm.com> for discovering
this issue. (CVE-2012-0884)
See the commit log message for that for more information.
NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.
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.
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.
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...
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.
be explicitly stated with PKCS#7 verify.
Also fix for util/mkerr.pl: if the -nostatic option is being used this will be
for an external library so the autogenerated C file should include the
header file as:
#include "any/path/to/header.h"
rather than the internal library form:
#include <openssl/header.h>
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...
