 Gnuk NEWS - User visible changes

+
+* Major changes in Gnuk 1.2.19
+
+  Released 2021-10-12, by NIIBE Yutaka
+
+** KDF Data Object configuration
+KDF Data Object should be highly recommended for all configurations.
+Nevertheless, for backward compatibillity, in Gnuk 1.2, it is optional
+by default; It is up to user to configure KDF Data Object before
+importing private keys.  In this situation, it is not good to
+introduce new build-time option like --enable-always-require-kdf-do,
+because it might wrongly encourage use of Gnuk with no KDF Data Object
+setting, by confusion.  If needed, please run configure:
+
+  kdf_do=required ./configure --enable-factory-reset --target...
+
+or
+
+  kdf_do=optional ./configure --enable-factory-reset --target...
+
+Please note that such a use of variable by shell command line is not
+well supported by the configure script (for other variables), but
+override of kdf_do is needed in some situations.
+
+** Upgrade of Chopstx
+We use Chopstx 1.20.  This enables use with PC/SC for GNU/Linux
+emulation.
+
+
+* Major changes in Gnuk 1.2.18
+
+  Released 2021-04-02, by NIIBE Yutaka
+
+** GNU/Linux emulation bug fix
+This time, for GNU/Linux emulation, KDF Data Object is required before
+keygen and key import, really.
+
+** tool/upgrade_by_passwd.py
+Now, it checks if the target of binary being written and the
+configured target of running device are same.  This check can be
+skipped by -s option.  Please note that FST-01 and FST-01SZ are
+different target, as it's MHz is different.
+
+
+* Major changes in Gnuk 1.2.17
+
+  Released 2021-02-25, by NIIBE Yutaka
+
+** GNU/Linux: KDF Data Object is required before keygen and key import
+For GNU/Linux emulation, KDF Data Object is required before keygen and
+key import.
+
+** GNU/Linux emulation
+Since 1.2.10, it was not build-able because of MHZ definition.  It is
+build-able again, and its USB product string is now "Gnuk Token".  It
+has ACK button support using terminal.  It now has start-up message,
+and its driver show useful information to setup USBIP.  When no file
+for the .gnuk-flash-image file, it is automatically created.
+
+** Removal of tool/gnuk-emulation-setup
+Because it is automatically created, the tool is not needed any more.
+
+** Upgrade of Chopstx
+We use Chopstx 1.19.
+
+
+* Major changes in Gnuk 1.2.16
+
+  Released 2020-09-10, by NIIBE Yutaka
+
+** New Data Object (Algorithm Information) of OpenPGP card v3.4
+The tag is 0x00FA.  This is useful for user interaction to show which
+algorithms are supported by the device.
+
+** Ed25519 signing allowing longer message
+For OpenPGP, it does hashing on host side before requesting signing to
+the device.  Thus, the length of message to be signed is limited and
+determined by the hash algorithm.  That's good feature of OpenPGP.  On
+the other hand, there is a use case, like OpenSSH certificate signing,
+where the length of message is a kind of arbitrary.  Even though Gnuk
+(or OpenPGP card protocol itself) has limitation, we removed the
+length check against EDDSA_HASH_LEN_MAX at cmd_pso.
+
+
+* Major changes in Gnuk 1.2.15
+
+  Released 2020-01-24, by NIIBE Yutaka
+
+** Switch to Python3
+Scripts under tool/ are switched to Python3.
+Thanks to Bertrand Jacquin.
+
+** Upgrade of Chopstx
+We use Chopstx 1.18.
+
+** Tests also support OpenPGPcard

+
+** DFU support and its firmware upgrade fix
+DFU support was not well maintained, and firmware upgrade was not
+possible for boards with DFU.  Now, at least for Maple Mini, it is
+tested.  Note that using Gnuk with DFU on a board is only for an
+experiment, because DFU can access the content of flash ROM.  DFU
+should be killed by upgrading to normal Gnuk, so that you can have
+your private keys.
+
+** Fix for UIF Data Object
+When flash ROM is full and coping to new page, UIF DO was not properly
+copied.  This bug resulted losing the flag for user interaction.  Now,
+it's properly copied, keeping the setting of the feature.

+While OpenPGP card specification verison 3 has description for the

+
+  Released 2018-04-05, by NIIBE Yutaka
+
+** A test suite fix: Clear PW3
+Until 1.2.8, after running the test suite under "tests", PW3 keystring
+remained, which affects use of admin-less mode.  New test case is
+added to clear PW3.
+
+** tool/upgrade_by_passwd.py supports KDF-DO auth
+With KDF-DO, firmware upgrade didn't work.  Now, it's supported.
+
+** Add "single-salt" support for KDF-DO
+With KDF-DO, "admin-less" mode didn't work well.  With new feature of
+"single-salt" support, we can use "admin-less" mode with KDF-DO.

+
+  Released 2018-01-23, by NIIBE Yutaka
+
+** No inclusion of VID:PID in gnuk.elf
+
+Distribution of binary image with VID:PID would violate vendor ID
+agreement to USB Forum.  Now, we have new file named gnuk-vidpid.elf
+for flashing.  The file gnuk.elf can be used to generate
+gnuk-vidpid.elf and we can check if it is reproducible or not.
+
+** Passphrase length check
+
+Now, Gnuk checks length of passphrase if it's too short when
+changing passphrase.
+
+** Remove unused DEK with BY_ADMIN
+
+For admin-less mode, DEK by OPENPGP_CARD_INITIAL_PW3 remained on flash
+ROM.  This could be considered a backdoor, if some other person had or
+kept access to the flash ROM, cheating a user.  Now, the DEK is
+cleared by zero when the token is set to admin-less mode.
+
+** Upgrade of Chopstx
+We use Chopstx 1.8.

+has experimental support of ECDSA (on NIST P256 and secp256k1) and
+ECDH (on NIST P256 and secp256k1).

 It also supports RSA-4096, but users should know that it takes more
 than 8 seconds to sign/decrypt.  Key generation of RSA-4096 just fails,
 because the device doesn't have enough memory.

+It supports new KDF-DO feature.  Please note that this is
+experimental.  To use the feature, you need to use newer GnuPG (2.2.6
+or later).  You need to prepare the KDF-DO on your token by the

+is available for test.
