Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
sets the subject name for a new request or supersedes the
subject name in a given request. Formats that can be parsed are
'CN=Some Name, OU=myOU, C=IT'
and
'CN=Some Name/OU=myOU/C=IT'.
Add options '-batch' and '-verbose' to 'openssl req'.

*) Introduce the possibility to access global variables through
functions on platform were that's the best way to handle exporting
global variables in shared libraries. To enable this functionality,
one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
"OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
is normally done by Configure or something similar).
To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
in the source file (foo.c) like this:
OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
OPENSSL_IMPLEMENT_GLOBAL(double,bar);
To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
OPENSSL_DECLARE_GLOBAL(int,foo);
#define foo OPENSSL_GLOBAL_REF(foo)
OPENSSL_DECLARE_GLOBAL(double,bar);
#define bar OPENSSL_GLOBAL_REF(bar)
The #defines are very important, and therefore so is including the
header file everywere where the defined globals are used.
The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
of ASN.1 items, but that structure is a bt different.
The largest change is in util/mkdef.pl which has been enhanced with
better and easier to understand logic to choose which symbols should
go into the Windows .def files as well as a number of fixes and code
cleanup (among others, algorithm keywords are now sorted
lexicographically to avoid constant rewrites).
[Richard Levitte]
*) In copy_email() check for >= 0 as a return value for
X509_NAME_get_index_by_NID() since 0 is a valid index.
[Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
*) In BN_div() keep a copy of the sign of 'num' before writing the
result to 'rm' because if rm==num the value will be overwritten
and produce the wrong result if 'num' is negative: this caused
problems with BN_mod() and BN_nnmod().
[Steve Henson]
*) Function OCSP_request_verify(). This checks the signature on an
OCSP request and verifies the signer certificate. The signer
certificate is just checked for a generic purpose and OCSP request
trust settings.
[Steve Henson]
*) Add OCSP_check_validity() function to check the validity of OCSP
responses. OCSP responses are prepared in real time and may only
be a few seconds old. Simply checking that the current time lies
between thisUpdate and nextUpdate max reject otherwise valid responses
caused by either OCSP responder or client clock innacuracy. Instead
we allow thisUpdate and nextUpdate to fall within a certain period of
the current time. The age of the response can also optionally be
checked. Two new options -validity_period and -status_age added to
ocsp utility.
[Steve Henson]
*) If signature or public key algorithm is unrecognized print out its
OID rather that just UNKOWN.
[Steve Henson]
*) Avoid coredump with unsupported or invalid public keys by checking if
X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
PKCS7_verify() fails with non detached data.
[Steve Henson]
*) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
ID to be generated from the issuer certificate alone which can then be
passed to OCSP_id_issuer_cmp().
[Steve Henson]
*) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
ASN1 modules to export functions returning ASN1_ITEM pointers
instead of the ASN1_ITEM structures themselves. This adds several
new macros which allow the underlying ASN1 function/structure to
be accessed transparently. As a result code should not use ASN1_ITEM
references directly (such as &X509_it) but instead use the relevant
macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
use of the new ASN1 code on platforms where exporting structures
is problematical (for example in shared libraries) but exporting
functions returning pointers to structures is not.
[Steve Henson]
*) Add support for overriding the generation of SSL/TLS session IDs.
These callbacks can be registered either in an SSL_CTX or per SSL.
The purpose of this is to allow applications to control, if they wish,
the arbitrary values chosen for use as session IDs, particularly as it
can be useful for session caching in multiple-server environments. A
command-line switch for testing this (and any client code that wishes
to use such a feature) has been added to "s_server".
[Geoff Thorpe, Lutz Jaenicke]
*) Modify mkdef.pl to recognise and parse prprocessor conditionals
of the form '#if defined(...) || defined(...) || ...' and
'#if !defined(...) && !defined(...) && ...'. This also avoids
the growing number of special cases it was previously handling.
[Richard Levitte]
*) Don't use getenv in library functions when run as setuid/setgid.
New function OPENSSL_issetugid().
[Ulf Moeller]
*) Make all configuration macros available for application by making
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.
Additionally, it is now possible to define configuration/platform-
specific names (called "system identities"). In the C code, these
are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
macro with the name beginning with "OPENSSL_SYS_", which is determined
from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
what is available.
[Richard Levitte]
*) New option -set_serial to 'req' and 'x509' this allows the serial
number to use to be specified on the command line. Previously self
signed certificates were hard coded with serial number 0 and the
CA options of 'x509' had to use a serial number in a file which was
auto incremented.
[Steve Henson]
*) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
due to incorrect handling of multi-threading:
1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
3. Count how many times MemCheck_off() has been called so that
nested use can be treated correctly. This also avoids
inband-signalling in the previous code (which relied on the
assumption that thread ID 0 is impossible).
[Bodo Moeller]
*) New options to 'ca' utility to support V2 CRL entry extensions.
Currently CRL reason, invalidity date and hold instruction are
supported. Add new CRL extensions to V3 code and some new objects.
[Steve Henson]
*) Add "-rand" option also to s_client and s_server.
[Lutz Jaenicke]
*) New function EVP_CIPHER_CTX_set_padding() this is used to
disable standard block padding (aka PKCS#5 padding) in the EVP
API, which was previously mandatory. This means that the data is
not padded in any way and so the total length much be a multiple
of the block size, otherwise an error occurs.
[Steve Henson]
*) Initial (incomplete) OCSP SSL support.
[Steve Henson]
*) Fix CPU detection on Irix 6.x.
[Kurt Hockenbury <khockenb@stevens-tech.edu> and
"Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
*) New function OCSP_parse_url(). This splits up a URL into its host,
port and path components: primarily to parse OCSP URLs. New -url
option to ocsp utility.
[Steve Henson]
*) New nonce behavior. The return value of OCSP_check_nonce() now
reflects the various checks performed. Applications can decide
whether to tolerate certain situations such as an absent nonce
in a response when one was present in a request: the ocsp application
just prints out a warning. New function OCSP_add1_basic_nonce()
this is to allow responders to include a nonce in a response even if
the request is nonce-less.
[Steve Henson]
*) Use the cached encoding of an X509_NAME structure rather than
copying it. This is apparently the reason for the libsafe "errors"
but the code is actually correct.
[Steve Henson]
*) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
skipped when using openssl x509 multiple times on a single input file,
e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
