Noteworthy changes in version 1.6.3 (2015-02-27) [C20/A0/R3]
------------------------------------------------
* Use ciphertext blinding for Elgamal decryption [CVE-2014-3591].
See http://www.cs.tau.ac.il/~tromer/radioexp/ for details.
* Fixed data-dependent timing variations in modular exponentiation
[related to CVE-2015-0837, Last-Level Cache Side-Channel Attacks
are Practical].
* Improved asm support for older toolchains.
Noteworthy changes in version 1.6.2 (2014-08-21) [C20/A0/R2]
------------------------------------------------
* Map deprecated RSA algo number to the RSA algo number for better
backward compatibility.
* Support a 0x40 compression prefix for EdDSA.
* Improve ARM hardware feature detection and building.
* Fix powerpc-apple-darwin detection
* Fix building for the x32 ABI platform.
* Support building using the latest mingw-w64 toolchain.
* Fix some possible NULL deref bugs.
libgcrypt installs a library and 3 binaries, none of which are linked
against pthreads (on NetBSD 6). It installs one .h, which also does
not reference pthreads. However, it contains a comment that thread
callbacks were removed from libgcrypt as of 1.6. I rebuilt dirmngr,
glib-networking, gnupg2, libgnome-keyring, libksba, libotr, libxslt,
and pidgin-otr with the new version with no issues.
Note that I am not removing mk/pthread.buildlink3.mk from Makefile,
because it builds t-lock (used in make test but not installed) with
threads.
Noteworthy changes in version 1.6.1 (2014-01-29)
------------------------------------------------
* Added emulation for broken Whirlpool code prior to 1.6.0.
* Improved performance of KDF functions.
* Improved ECDSA compliance.
* Fixed locking for Windows and non-ELF Pthread systems (regression
in 1.6.0)
* Fixed message digest lookup by OID (regression in 1.6.0).
* Fixed a build problem on NetBSD.
* Fixed memory leaks in ECC code.
* Fixed some asm build problems and feature detection bugs.
* Interface changes relative to the 1.6.0 release:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
GCRY_MD_FLAG_BUGEMU1 NEW (minor API change).
expressions containing a '/' (divide) are problematic because according to
the SUN x86 Assembly Language Reference Manual, '/' should be treated as
starting comments.
To get over this, gas has '--divide' do not treat `/' as a comment character
Noteworthy changes in version 1.6.0 (2013-12-16)
------------------------------------------------
* Removed the long deprecated gcry_ac interface. Thus Libgcrypt is
not anymore ABI compatible to previous versions if they used the ac
interface.
* Removed the module register subsystem.
* The deprecated message digest debug macros have been removed. Use
gcry_md_debug instead.
* Removed deprecated control codes.
* Improved performance of most cipher algorithms as well as for the
SHA family of hash functions.
* Added support for the IDEA cipher algorithm.
* Added support for the Salsa20 and reduced Salsa20/12 stream ciphers.
* Added limited support for the GOST 28147-89 cipher algorithm.
* Added support for the GOST R 34.11-94 and R 34.11-2012 (Stribog)
hash algorithms.
* Added a random number generator to directly use the system's RNG.
Also added an interface to prefer the use of a specified RNG.
* Added support for the SCRYPT algorithm.
* Mitigated the Yarom/Falkner flush+reload side-channel attack on RSA
secret keys. See <http://eprint.iacr.org/2013/448> [CVE-2013-4242].
* Added support for Deterministic DSA as per RFC-6969.
* Added support for curve Ed25519.
* Added a scatter gather hash convenience function.
* Added several MPI amd SEXP helper functions.
* Added support for negative numbers to gcry_mpi_print,
gcry_mpi_aprint and gcry_mpi_scan.
* The algorithm ids GCRY_PK_ECDSA and GCRY_PK_ECDH are now
deprecated. Use GCRY_PK_ECC if you need an algorithm id.
* Changed gcry_pk_genkey for "ecc" to only include the curve name and
not the parameters. The flag "param" may be used to revert this.
* Added a feature to globally disable selected hardware features.
* Added debug helper functions.
Noteworthy changes in version 1.5.3 (2013-07-25)
------------------------------------------------
* Mitigate the Yarom/Falkner flush+reload side-channel attack on
RSA secret keys. See <http://eprint.iacr.org/2013/448>.
XXX: lots of patches without comments, and not upstreamed it seems.
Noteworthy changes in version 1.5.2 (2013-04-18)
------------------------------------------------
* Added support for IDEA.
* Made the Padlock code work again (regression since 1.5.0).
* Fixed alignment problems for Serpent.
* Fixed two bugs in ECC computations.
* New function gcry_kdf_derive implementing OpenPGP S2K algorithms
and PBKDF2.
* Support for WindowsCE.
* Support for ECDH.
* Support for OAEP and PSS methods as described by RFC-3447.
* Fixed PKCS v1.5 code to always return the leading zero.
* New format specifiers "%M" and "%u" for gcry_sexp_build.
* Support opaque MPIs with "%m" and "%M" in gcry_sexp_build.
* New functions gcry_pk_get_curve and gcry_pk_get_param to map ECC
parameters to a curve name and to retrieve parameter values.
* gcry_mpi_cmp applied to opaque values has a defined semantic now.
* Uses the Intel AES-NI instructions if available.
* The use of the deprecated Alternative Public Key Interface
(gcry_ac_*) will now print compile time warnings.
* The module register subsystem has been deprecated. This subsystem
is not flexible enough and would always require ABI changes to
extend the internal interfaces. It will eventually be removed.
Please contact us on the gcrypt-devel mailing list to discuss
whether you really need this feature or how it can be replaced by
an internal plugin mechanism.
* CTR mode may now be used with data chunks of arbitrary length.
* New variants of the TIGER algorithm.
* New cipher algorithm mode for AES-WRAP.
* Interface changes relative to the 1.4.2 release:
GCRY_MD_TIGER1 NEW.
GCRY_MD_TIGER2 NEW.
GCRY_CIPHER_MODE_AESWRAP NEW.
Noteworthy changes in version 1.4.5 (2009-12-11)
------------------------------------------------
* Fixed minor memory leak in DSA key generation.
* No more switching to FIPS mode if /proc/version is not readable.
* Fixed a sigill during Padlock detection on old CPUs.
* Fixed a hang on some W2000 machines.
* Boosted SHA-512 performance by 30% on ia32 boxes and gcc 4.3;
SHA-256 went up by 25%.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
* Publish GCRY_MODULE_ID_USER and GCRY_MODULE_ID_USER_LAST constants.
This functionality has been in Libgcrypt since 1.3.0.
* MD5 may now be used in non-enforced fips mode.
* Fixed HMAC for SHA-384 and SHA-512 with keys longer than 64 bytes.
* In fips mode, RSA keys are now generated using the X9.31 algorithm
and DSA keys using the FIPS 186-2 algorithm.
* The transient-key flag is now also supported for DSA key
generation. DSA domain parameters may be given as well.
is incorrect because:
1) _gcry_rngfips_deinit_external_test() is void function
2) the calling function, random, is declared void
The unpatched code will not compile with Sun compiler.
* Try to auto-initialize Libgcrypt to minimize the effect of
applications not doing that correctly. This is not a perfect
solution but given that many applicationion would totally fail
without such a hack, we try to help at least with the most common
cases. Folks, please read the manual to learn how to properly
initialize Libgcrypt!
* Auto-initialize the secure memory to 32k instead of aborting the
process.
* Log fatal errors via syslog.
* Changed the name and the semantics of the fips mode config file.
* Add convenience macro gcry_fips_mode_active.
* More self-tests.
* Documentation cleanups.
Noteworthy changes in version 1.4.1 (2008-04-25)
------------------------------------------------
* Fixed a bug introduced by 1.3.1 which led to the comsumption of far
too much entropy for the intial seeding.
* Improved AES performance for CFB and CBC modes.
* Removed build problems for the Padlock support.
VIA PadLock Security Engine:
- The new option is turned on by default.
- The new option is only available on i386 systems except Mac OS X (which
doesn't work on VIA CPU).
- The new option isn't available on system which uses GCC 3.x because it
causes build failures. This fixes PR pkg/38197.
Approved by Dieter Baron.
