Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Make sk_sort() tolerate a NULL argument.
[Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
*) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
passed by the function are trusted implicitly. If any of them signed the
reponse then it is assumed to be valid and is not verified.
[Steve Henson]
*) Zero the premaster secret after deriving the master secret in
DH ciphersuites.
[Steve Henson]
*) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
to data. This was previously part of the PKCS7 ASN1 code. This
was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
[Steve Henson, reported by Kenneth R. Robinette
<support@securenetterm.com>]
*) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
routines: without these tracing memory leaks is very painful.
Fix leaks in PKCS12 and PKCS7 routines.
[Steve Henson]
*) Fix for Irix with NO_ASM.
["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
*) Add some EVP_add_digest_alias registrations (as found in
OpenSSL_add_all_digests()), to SSL_library_init()
aka OpenSSL_add_ssl_algorithms(). This provides improved
compatibility with peers using X.509 certificates
with unconventional AlgorithmIdentifier OIDs.
[Bodo Moeller]
*) ./config script fixes.
[Ulf Moeller, Richard Levitte]
*) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
effectively meant GeneralizedTime would never be used. Now it
is initialised to -1 but X509_time_adj() now has to check the value
and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
[Steve Henson, reported by Kenneth R. Robinette
<support@securenetterm.com>]
*) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
result in a zero length in the ASN1_INTEGER structure which was
not consistent with the structure when d2i_ASN1_INTEGER() was used
and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
where it did not print out a minus for negative ASN1_INTEGER.
[Steve Henson]
*) 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
Richard Levitte
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
