Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Add summary printout to ocsp utility. The various functions which
convert status values to strings have been renamed to:
OCSP_response_status_str(), OCSP_cert_status_str() and
OCSP_crl_reason_str() and are no longer static. New options
to verify nonce values and to disable verification. OCSP response
printout format cleaned up.
[Steve Henson]
*) Add additional OCSP certificate checks. These are those specified
in RFC2560. This consists of two separate checks: the CA of the
certificate being checked must either be the OCSP signer certificate
or the issuer of the OCSP signer certificate. In the latter case the
OCSP signer certificate must contain the OCSP signing extended key
usage. This check is performed by attempting to match the OCSP
signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
in the OCSP_CERTID structures of the response.
[Steve Henson]
*) Initial OCSP certificate verification added to OCSP_basic_verify()
and related routines. This uses the standard OpenSSL certificate
verify routines to perform initial checks (just CA validity) and
to obtain the certificate chain. Then additional checks will be
performed on the chain. Currently the root CA is checked to see
if it is explicitly trusted for OCSP signing. This is used to set
a root CA as a global signing root: that is any certificate that
chains to that CA is an acceptable OCSP signing certificate.
[Steve Henson]
*) New '-extfile ...' option to 'openssl ca' for reading X.509v3
extensions from a separate configuration file.
As when reading extensions from the main configuration file,
the '-extensions ...' option may be used for specifying the
section to use.
[Massimiliano Pala <madwolf@comune.modena.it>]
*) Change PKCS12_key_gen_asc() so it can cope with non null
terminated strings whose length is passed in the passlen
parameter, for example from PEM callbacks. This was done
by adding an extra length parameter to asc2uni().
[Steve Henson, reported by <oddissey@samsung.co.kr>]
*) New OCSP utility. Allows OCSP requests to be generated or
read. The request can be sent to a responder and the output
parsed, outputed or printed in text form. Not complete yet:
still needs to check the OCSP response validity.
[Steve Henson]
*) New subcommands for 'openssl ca':
'openssl ca -status <serial>' prints the status of the cert with
the given serial number (according to the index file).
'openssl ca -updatedb' updates the expiry status of certificates
in the index file.
[Massimiliano Pala <madwolf@comune.modena.it>]
*) New '-newreq-nodes' command option to CA.pl. This is like
'-newreq', but calls 'openssl req' with the '-nodes' option
so that the resulting key is not encrypted.
[Damien Miller <djm@mindrot.org>]
*) New configuration for the GNU Hurd.
[Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
*) Initial code to implement OCSP basic response verify. This
is currently incomplete. Currently just finds the signer's
certificate and verifies the signature on the response.
[Steve Henson]
*) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
value of OPENSSLDIR. This is available via the new '-d' option
to 'openssl version', and is also included in 'openssl version -a'.
[Bodo Moeller]
*) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
call failed, free the DSA structure.
[Bodo Moeller]
*) Allowing defining memory allocation callbacks that will be given
file name and line number information in additional arguments
(a const char* and an int). The basic functionality remains, as
well as the original possibility to just replace malloc(),
realloc() and free() by functions that do not know about these
additional arguments. To register and find out the current
settings for extended allocation functions, the following
functions are provided:
CRYPTO_set_mem_ex_functions
CRYPTO_set_locked_mem_ex_functions
CRYPTO_get_mem_ex_functions
CRYPTO_get_locked_mem_ex_functions
These work the same way as CRYPTO_set_mem_functions and friends.
CRYPTO_get_[locked_]mem_functions now writes 0 where such an
extended allocation function is enabled.
Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
a conventional allocation function is enabled.
[Richard Levitte, Bodo Moeller]
*) Fix to uni2asc() to cope with zero length Unicode strings.
These are present in some PKCS#12 files.
[Steve Henson]
*) Finish off removing the remaining LHASH function pointer casts.
There should no longer be any prototype-casting required when using
the LHASH abstraction, and any casts that remain are "bugs". See
the callback types and macros at the head of lhash.h for details
(and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
[Geoff Thorpe]
*) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
If an EGD or PRNGD is running and enough entropy is returned, automatic
seeding like with /dev/[u]random will be performed.
Positions tried are: /etc/entropy, /var/run/egd-pool.
[Lutz Jaenicke]
*) Change the Unix RAND_poll() variant to be able to poll several

committed
random devices, as specified by DEVRANDOM, until a sufficient amount
of data has been collected. We spend at most 10 ms on each file
(select timeout) and read in non-blocking mode. DEVRANDOM now
defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
(previously it was just the string "/dev/urandom"), so on typical
platforms the 10 ms delay will never occur.
Also separate out the Unix variant to its own file, rand_unix.c.
For VMS, there's a currently-empty rand_vms.c.
[Richard Levitte]
*) Move OCSP client related routines to ocsp_cl.c. These
provide utility functions which an application needing
to issue a request to an OCSP responder and analyse the
response will typically need: as opposed to those which an
OCSP responder itself would need which will be added later.
OCSP_request_sign() signs an OCSP request with an API similar
to PKCS7_sign(). OCSP_response_status() returns status of OCSP
response. OCSP_response_get1_basic() extracts basic response
from response. OCSP_resp_find_status(): finds and extracts status
information from an OCSP_CERTID structure (which will be created
when the request structure is built). These are built from lower
level functions which work on OCSP_SINGLERESP structures but
wont normally be used unless the application wishes to examine
extensions in the OCSP response for example.
Replace nonce routines with a pair of functions.
OCSP_request_add1_nonce() adds a nonce value and optionally
generates a random value. OCSP_check_nonce() checks the
validity of the nonce in an OCSP response.
[Steve Henson]
*) Change function OCSP_request_add() to OCSP_request_add0_id().
This doesn't copy the supplied OCSP_CERTID and avoids the
need to free up the newly created id. Change return type
to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
This can then be used to add extensions to the request.
Deleted OCSP_request_new(), since most of its functionality
is now in OCSP_REQUEST_new() (and the case insensitive name
clash) apart from the ability to set the request name which
will be added elsewhere.
[Steve Henson]
*) Update OCSP API. Remove obsolete extensions argument from
various functions. Extensions are now handled using the new
OCSP extension code. New simple OCSP HTTP function which
can be used to send requests and parse the response.
[Steve Henson]
*) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
uses the special reorder version of SET OF to sort the attributes
and reorder them to match the encoded order. This resolves a long
standing problem: a verify on a PKCS7 structure just after signing
it used to fail because the attribute order did not match the
encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
it uses the received order. This is necessary to tolerate some broken
software that does not order SET OF. This is handled by encoding
as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
to produce the required SET OF.
[Steve Henson]
*) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
files to get correct declarations of the ASN.1 item variables.
[Richard Levitte]
*) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
ASN1_ITEM and no wrapper functions.
[Steve Henson]
*) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
replace the old function pointer based I/O routines. Change most of
