Changes between 0.9.8j and 0.9.9 [xx XXX xxxx]
*) Enhance the hash format used for certificate directory links. The new
form uses the canonical encoding (meaning equivalent names will work
even if they aren't identical) and uses SHA1 instead of MD5. This form
is incompatible with the older format and as a result c_rehash should
be used to rebuild symbolic links.
[Steve Henson]
*) Make PKCS#8 the default write format for private keys, replacing the
traditional format. This form is standardised, more secure and doesn't
include an implicit MD5 dependency.
[Steve Henson]
*) Add a $gcc_devteam_warn option to Configure. The idea is that any code
committed to OpenSSL should pass this lot as a minimum.
[Steve Henson]
*) Add session ticket override functionality for use by EAP-FAST.
[Jouni Malinen <j@w1.fi>]
*) Modify HMAC functions to return a value. Since these can be implemented
in an ENGINE errors can occur.
[Steve Henson]
*) Type-checked OBJ_bsearch_ex.
[Ben Laurie]
*) Type-checked OBJ_bsearch. Also some constification necessitated
by type-checking. Still to come: TXT_DB, bsearch(?),
OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING,

*) New function OPENSSL_gmtime_adj() to add a specific number of days and
seconds to a tm structure directly, instead of going through OS
specific date routines. This avoids any issues with OS routines such
as the year 2038 bug. New *_adj() functions for ASN1 time structures
and X509_time_adj_ex() to cover the extended range. The existing
X509_time_adj() is still usable and will no longer have any date issues.

*) Delta CRL support. New use deltas option which will attempt to locate
and search any appropriate delta CRLs available.
This work was sponsored by Google.
[Steve Henson]
*) Support for CRLs partitioned by reason code. Reorganise CRL processing
code and add additional score elements. Validate alternate CRL paths
as part of the CRL checking and indicate a new error "CRL path validation
error" in this case. Applications wanting additional details can use
the verify callback and check the new "parent" field. If this is not
NULL CRL path validation is taking place. Existing applications wont
see this because it requires extended CRL support which is off by
default.

[Steve Henson]
*) Support for freshest CRL extension.
This work was sponsored by Google.
[Steve Henson]
*) Initial indirect CRL support. Currently only supported in the CRLs
passed directly and not via lookup. Process certificate issuer
CRL entry extension and lookup CRL entries by bother issuer name
and serial number. Check and process CRL issuer entry in IDP extension.
This work was sponsored by Google.

*) Add support for distinct certificate and CRL paths. The CRL issuer
certificate is validated separately in this case. Only enabled if
an extended CRL support flag is set: this flag will enable additional
CRL functionality in future.
This work was sponsored by Google.
[Steve Henson]
*) Add support for policy mappings extension.
This work was sponsored by Google.
[Steve Henson]
*) Fixes to pathlength constraint, self issued certificate handling,
policy processing to align with RFC3280 and PKITS tests.
This work was sponsored by Google.
[Steve Henson]
*) Support for name constraints certificate extension. DN, email, DNS
and URI types are currently supported.
This work was sponsored by Google.
[Steve Henson]
*) To cater for systems that provide a pointer-based thread ID rather
than numeric, deprecate the current numeric thread ID mechanism and
replace it with a structure and associated callback type. This
mechanism allows a numeric "hash" to be extracted from a thread ID in
either case, and on platforms where pointers are larger than 'long',
mixing is done to help ensure the numeric 'hash' is usable even if it
can't be guaranteed unique. The default mechanism is to use "&errno"
as a pointer-based thread ID to distinguish between threads.
Applications that want to provide their own thread IDs should now use
CRYPTO_THREADID_set_callback() to register a callback that will call
either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().
Note that ERR_remove_state() is now deprecated, because it is tied
to the assumption that thread IDs are numeric. ERR_remove_state(0)
to free the current thread's error state should be replaced by
ERR_remove_thread_state(NULL).
(This new approach replaces the functions CRYPTO_set_idptr_callback(),
CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
application was previously providing a numeric thread callback that
was inappropriate for distinguishing threads, then uniqueness might
have been obtained with &errno that happened immediately in the
intermediate development versions of OpenSSL; this is no longer the
case, the numeric thread callback will now override the automatic use
of &errno.)
[Geoff Thorpe, with help from Bodo Moeller]
*) Initial support for different CRL issuing certificates. This covers a
simple case where the self issued certificates in the chain exist and
the real CRL issuer is higher in the existing chain.
This work was sponsored by Google.
[Steve Henson]
*) Removed effectively defunct crypto/store from the build.
[Ben Laurie]
*) Revamp of STACK to provide stronger type-checking. Still to come:
TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE,
ASN1_STRING, CONF_VALUE.
[Ben Laurie]
*) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer
RAM on SSL connections. This option can save about 34k per idle SSL.
[Nick Mathewson]
*) Revamp of LHASH to provide stronger type-checking. Still to come:
STACK, TXT_DB, bsearch, qsort.
[Ben Laurie]
*) Initial support for Cryptographic Message Syntax (aka CMS) based
on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
support for data, signedData, compressedData, digestedData and
encryptedData, envelopedData types included. Scripts to check against
RFC4134 examples draft and interop and consistency checks of many
content types and variants.
*) Add options to enc utility to support use of zlib compression BIO.
*) Extend mk1mf to support importing of options and assembly language
files from Configure script, currently only included in VC-WIN32.
The assembly language rules can now optionally generate the source
files from the associated perl scripts.
[Steve Henson]
*) Implement remaining functionality needed to support GOST ciphersuites.
Interop testing has been performed using CryptoPro implementations.
[Victor B. Wagner <vitus@cryptocom.ru>]
*) s390x assembler pack.
[Andy Polyakov]
*) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU
"family."
[Andy Polyakov]
*) Implement Opaque PRF Input TLS extension as specified in
draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an
official specification yet and no extension type assignment by
IANA exists, this extension (for now) will have to be explicitly
enabled when building OpenSSL by providing the extension number
to use. For example, specify an option
-DTLSEXT_TYPE_opaque_prf_input=0x9527
to the "config" or "Configure" script to enable the extension,
assuming extension number 0x9527 (which is a completely arbitrary
and unofficial assignment based on the MD5 hash of the Internet
Draft). Note that by doing so, you potentially lose
interoperability with other TLS implementations since these might
be using the same extension number for other purposes.
SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the
opaque PRF input value to use in the handshake. This will create
Loading full blame...
