Changes between 0.9.7h and 0.9.8 [xx XXX xxxx]
*) Correct naming of the 'chil' and '4758cca' ENGINEs. This
involves renaming the source and generated shared-libs for
both. The engines will accept the corrected or legacy ids
('ncipher' and '4758_cca' respectively) when binding. NB,
this only applies when building 'shared'.
[Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
*) Add attribute functions to EVP_PKEY structure. Modify
PKCS12_create() to recognize a CSP name attribute and
use it. Make -CSP option work again in pkcs12 utility.
[Steve Henson]
*) Add new functionality to the bn blinding code:
- automatic re-creation of the BN_BLINDING parameters after
a fixed number of uses (currently 32)
- add new function for parameter creation
- introduce flags to control the update behaviour of the
BN_BLINDING parameters
- hide BN_BLINDING structure
Add a second BN_BLINDING slot to the RSA structure to improve
performance when a single RSA object is shared among several
threads.
[Nils Larsch]
*) Add support for DTLS.
[Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
*) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
[Walter Goulet]
*) Remove buggy and incompletet DH cert support from
ssl/ssl_rsa.c and ssl/s3_both.c
[Nils Larsch]
*) Use SHA-1 instead of MD5 as the default digest algorithm for
the apps/openssl applications.
[Nils Larsch]
*) Compile clean with "-Wall -Wmissing-prototypes
-Wstrict-prototypes -Wmissing-declarations -Werror". Currently
DEBUG_SAFESTACK must also be set.
[Ben Laurie]
*) Change ./Configure so that certain algorithms can be disabled by default.
The new counterpiece to "no-xxx" is "enable-xxx".
The patented RC5 and MDC2 algorithms will now be disabled unless
"enable-rc5" and "enable-mdc2", respectively, are specified.
(IDEA remains enabled despite being patented. This is because IDEA
is frequently required for interoperability, and there is no license
fee for non-commercial use. As before, "no-idea" can be used to
avoid this algorithm.)
[Bodo Moeller]
*) Add processing of proxy certificates (see RFC 3820). This work was
sponsored by KTH (The Royal Institute of Technology in Stockholm) and
EGEE (Enabling Grids for E-science in Europe).
[Richard Levitte]
*) RC4 performance overhaul on modern architectures/implementations, such
as Intel P4, IA-64 and AMD64.
[Andy Polyakov]

*) New utility extract-section.pl. This can be used specify an alternative
section number in a pod file instead of having to treat each file as
a separate case in Makefile. This can be done by adding two lines to the
pod file:
=for comment openssl_section:XXX
The blank line is mandatory.
[Steve Henson]
*) New arguments -certform, -keyform and -pass for s_client and s_server
to allow alternative format key and certificate files and passphrase
sources.
[Steve Henson]
*) New structure X509_VERIFY_PARAM which combines current verify parameters,
update associated structures and add various utility functions.
Add new policy related verify parameters, include policy checking in
standard verify code. Enhance 'smime' application with extra parameters
to support policy checking and print out.
[Steve Henson]
*) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
Nehemiah processors. These extensions support AES encryption in hardware
as well as RNG (though RNG support is currently disabled).
[Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
*) Deprecate BN_[get|set]_params() functions (they were ignored internally).
[Geoff Thorpe]
*) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
[Andy Polyakov and a number of other people]
*) Improved PowerPC platform support. Most notably BIGNUM assembler
implementation contributed by IBM.
[Suresh Chari, Peter Waltenberg, Andy Polyakov]
*) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
exponent rather than 'unsigned long'. There is a corresponding change to
the new 'rsa_keygen' element of the RSA_METHOD structure.
[Jelte Jansen, Geoff Thorpe]
*) Functionality for creating the initial serial number file is now
moved from CA.pl to the 'ca' utility with a new option -create_serial.
(Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
number file to 1, which is bound to cause problems. To avoid
the problems while respecting compatibility between different 0.9.7
patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
CA.pl for serial number initialization. With the new release 0.9.8,
we can fix the problem directly in the 'ca' utility.)

[Steve Henson]
*) Reduced header interdepencies by declaring more opaque objects in
ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
give fewer recursive includes, which could break lazy source code - so
this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
developers should define this symbol when building and using openssl to
ensure they track the recommended behaviour, interfaces, [etc], but
backwards-compatible behaviour prevails when this isn't defined.
[Geoff Thorpe]
*) New function X509_POLICY_NODE_print() which prints out policy nodes.
[Steve Henson]
*) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
This will generate a random key of the appropriate length based on the
cipher context. The EVP_CIPHER can provide its own random key generation
routine to support keys of a specific form. This is used in the des and
3des routines to generate a key of the correct parity. Update S/MIME
code to use new functions and hence generate correct parity DES keys.
Add EVP_CHECK_DES_KEY #define to return an error if the key is not
valid (weak or incorrect parity).
[Steve Henson]
*) Add a local set of CRLs that can be used by X509_verify_cert() as well
as looking them up. This is useful when the verified structure may contain
CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
present unless the new PKCS7_NO_CRL flag is asserted.
[Steve Henson]
*) Extend ASN1 oid configuration module. It now additionally accepts the
syntax:
shortName = some long name, 1.2.3.4
[Steve Henson]
*) Reimplemented the BN_CTX implementation. There is now no more static
limitation on the number of variables it can handle nor the depth of the
"stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
information can now expand as required, and rather than having a single
static array of bignums, BN_CTX now uses a linked-list of such arrays
allowing it to expand on demand whilst maintaining the usefulness of
BN_CTX's "bundling".
[Geoff Thorpe]
*) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
to allow all RSA operations to function using a single BN_CTX.
[Geoff Thorpe]
*) Preliminary support for certificate policy evaluation and checking. This
is initially intended to pass the tests outlined in "Conformance Testing
of Relying Party Client Certificate Path Processing Logic" v1.07.
[Steve Henson]
*) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
remained unused and not that useful. A variety of other little bignum
tweaks and fixes have also been made continuing on from the audit (see
below).
[Geoff Thorpe]
*) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
associated ASN1, EVP and SSL functions and old ASN1 macros.
[Richard Levitte]
*) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
and this should never fail. So the return value from the use of
BN_set_word() (which can fail due to needless expansion) is now deprecated;
if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
[Geoff Thorpe]
*) BN_CTX_get() should return zero-valued bignums, providing the same
