Changes between 0.9.7a and 0.9.8 [xx XXX xxxx]
*) Support for single pass processing for S/MIME signing. This now
means that S/MIME signing can be done from a pipe, in addition
cleartext signing (multipart/signed type) is effectively streaming
and the signed data does not need to be all held in memory.
This is done with a new flag PKCS7_PARTSIGN. When this flag is set
PKCS7_sign() only initializes the PKCS7 structure and the actual signing
is done after the data is output (and digests calculated) in
SMIME_write_PKCS7().
[Steve Henson]
*) Add full support for -rpath/-R, both in shared libraries and
applications, at least on the platforms where it's known how
to do it.
[Richard Levitte]
*) In crypto/ec/ec_mult.c, implement fast point multiplication with
will now compute a table of multiples of the generator that
faster (notably in the case of a single point multiplication,
scalar * generator).
[Nils Larsch, Bodo Moeller]
*) IPv6 support for certificate extensions. The various extensions
which use the IP:a.b.c.d can now take IPv6 addresses using the
formats of RFC1884 2.2 . IPv6 addresses are now also displayed
correctly.
[Steve Henson]
*) Added an ENGINE that implements RSA by performing private key
exponentiations with the GMP library. The conversions to and from
GMP's mpz_t format aren't optimised nor are any montgomery forms
cached, and on x86 it appears OpenSSL's own performance has caught up.
However there are likely to be other architectures where GMP could
provide a boost. This ENGINE is not built in by default, but it can be
specified at Configure time and should be accompanied by the necessary
linker additions, eg;
./config -DOPENSSL_USE_GMP -lgmp
[Geoff Thorpe]
*) "openssl engine" will not display ENGINE/DSO load failure errors when
testing availability of engines with "-t" - the old behaviour is
produced by increasing the feature's verbosity with "-tt".
[Geoff Thorpe]
*) ECDSA routines: under certain error conditions uninitialized BN objects
could be freed. Solution: make sure initialization is performed early
enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
via PR#459)
[Lutz Jaenicke]
*) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
and DH_METHOD (eg. by ENGINE implementations) to override the normal
software implementations. For DSA and DH, parameter generation can
also be overriden by providing the appropriate method callbacks.
[Geoff Thorpe]
*) Change the "progress" mechanism used in key-generation and
primality testing to functions that take a new BN_GENCB pointer in
place of callback/argument pairs. The new API functions have "_ex"
postfixes and the older functions are reimplemented as wrappers for
the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
declarations of the old functions to help (graceful) attempts to
migrate to the new functions. Also, the new key-generation API
functions operate on a caller-supplied key-structure and return
success/failure rather than returning a key or NULL - this is to
help make "keygen" another member function of RSA_METHOD etc.
Example for using the new callback interface:
int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
void *my_arg = ...;
BN_GENCB my_cb;
BN_GENCB_set(&my_cb, my_callback, my_arg);
return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
/* For the meaning of a, b in calls to my_callback(), see the
* documentation of the function that calls the callback.
* cb will point to my_cb; my_arg can be retrieved as cb->arg.
* my_callback should return 1 if it wants BN_is_prime_ex()
* to continue, or 0 to stop.
*/
[Geoff Thorpe]
*) Change the ZLIB compression method to be stateful, and make it
available to TLS with the number defined in
draft-ietf-tls-compression-04.txt.
[Richard Levitte]
*) Add the ASN.1 structures and functions for CertificatePair, which
is defined as follows (according to X.509_4thEditionDraftV6.pdf):
CertificatePair ::= SEQUENCE {
forward [0] Certificate OPTIONAL,
reverse [1] Certificate OPTIONAL,
-- at least one of the pair shall be present -- }
Also implement the PEM functions to read and write certificate
pairs, and defined the PEM tag as "CERTIFICATE PAIR".
This needed to be defined, mostly for the sake of the LDAP
attribute crossCertificatePair, but may prove useful elsewhere as
well.
[Richard Levitte]
*) Make it possible to inhibit symlinking of shared libraries in
Makefile.shared, for Cygwin's sake.
[Richard Levitte]
*) Extend the BIGNUM API by creating new macros that behave like
functions
void BN_set_sign(BIGNUM *a, int neg);
int BN_get_sign(const BIGNUM *a);
and avoid the need to access 'a->neg' directly in applications.
[Nils Larsch <nla@trustcenter.de>]
*) Implement fast modular reduction for pseudo-Mersenne primes
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
EC_GROUP_new_curve_GFp() will now automatically use this
if applicable.
[Nils Larsch <nla@trustcenter.de>]
*) Add new lock type (CRYPTO_LOCK_BN).
[Bodo Moeller]
*) Change the ENGINE framework to automatically load engines
dynamically from specific directories unless they could be
found to already be built in or loaded. Move all the
current engines except for the cryptodev one to a new
directory engines/.
The engines in engines/ are built as shared libraries if
the "shared" options was given to ./Configure or ./config.
Otherwise, they are inserted in libcrypto.a.
/usr/local/ssl/engines is the default directory for dynamic
engines, but that can be overriden at configure time through
the usual use of --prefix and/or --openssldir, and at run
time with the environment variable OPENSSL_ENGINES.
[Geoff Thorpe and Richard Levitte]
*) Add Makefile.shared, a helper makefile to build shared
libraries. Addapt Makefile.org.
[Richard Levitte]
*) Add version info to Win32 DLLs.
[Peter 'Luna' Runestig" <peter@runestig.com>]
*) Add new 'medium level' PKCS#12 API. Certificates and keys
can be added using this API to created arbitrary PKCS#12
files while avoiding the low level API.
New options to PKCS12_create(), key or cert can be NULL and
will then be omitted from the output file. The encryption
algorithm NIDs can be set to -1 for no encryption, the mac
iteration count can be set to 0 to omit the mac.
Enhance pkcs12 utility by making the -nokeys and -nocerts
options work when creating a PKCS#12 file. New option -nomac
to omit the mac, NONE can be set for an encryption algorithm.
New code is modified to use the enhanced PKCS12_create()
instead of the low level API.
[Steve Henson]
*) Extend ASN1 encoder to support indefinite length constructed
encoding. This can output sequences tags and octet strings in
this form. Modify pk7_asn1.c to support indefinite length
encoding. This is experimental and needs additional code to
be useful, such as an ASN1 bio and some enhanced streaming
PKCS#7 code.
Extend template encode functionality so that tagging is passed
down to the template encoder.
[Steve Henson]
*) Let 'openssl req' fail if an argument to '-newkey' is not
recognized instead of using RSA as a default.
[Bodo Moeller]
*) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
As these are not official, they are not included in "ALL";
the "ECCdraft" ciphersuite group alias can be used to select them.
[Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
*) Add ECDH engine support.
[Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
*) Add ECDH in new directory crypto/ecdh/.
