 Gnuk NEWS - User visible changes

+
+* Major changes in Gnuk 1.2.10
+
+  Released 2018-05-10, by NIIBE Yutaka
+
+** No inclusion of VID:PID in gnuk-no-vidpid.elf
+Now, we have new file named gnuk-no-vidpid.elf with no VID:PID.  The
+file gnuk.elf has the VID:PID, like version 1.2.7 or older.
+
+** Upgrade of Chopstx
+We use Chopstx 1.9, which supports GD32F103.
+
+
+* Major changes in Gnuk 1.2.9
+
+  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.
+
+** factory-reset deletes all upgrade public keys
+By card-edit/factory-reset by GnuPG, it deletes all upgrade public
+keys, now.
+
+
+* Major changes in Gnuk 1.2.8
+
+  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.
+
+
+* Major changes in Gnuk 1.2.7
+
+  Released 2017-11-26, by NIIBE Yutaka
+
+** reGNUal
+reGNUal enables CRC module by itself.
+
+** Flash update change
+CRC module is disabled when Gnuk stops.  It's reGNUal which needs to
+enable CRC module.
+
+** Support of USB suspend
+USB suspend and wakeup event are now handled.
+
+** KDF-DO support and KDF by host
+KDF-DO is now available.  Host can use this feature.
+
+** Upgrade of Chopstx
+We use Chopstx 1.6.
+
+
+* Major changes in Gnuk 1.2.6
+
+  Released 2017-10-11, by NIIBE Yutaka
+
+** Port to GNU/Linux emulation
+We can "run" Gnuk Token on GNU/Linux by emulation through USBIP.
+
+** Upgrade of Chopstx
+We use Chopstx 1.5.
+
+
+* Major changes in Gnuk 1.2.5
+
+  Released 2017-08-11, by NIIBE Yutaka
+
+** "factory-reset" fix
+Gnuk's behavior was implemented by referring the gpg implementation.
+It found that gpg implementation was not good from the viewpoint of
+the OpenPGP card specification.  GnuPG was fixed to match the OpenPGP
+card specification already.  Thus, Gnuk is now fixed.
+
+** Upgrade of Chopstx
+We use Chopstx 1.4.
+
+
+* Major changes in Gnuk 1.2.4
+
+  Released 2017-05-12, by NIIBE Yutaka
+
+** Flash ROM security fix
+The partial content of flash ROM might be exposed when scanning of
+data object had a problem.  Added boundary check and changed layout of
+flash ROM.
+
+
+* Major changes in Gnuk 1.2.3
+
+  Released 2017-02-02, by NIIBE Yutaka
+
+** ECC key generation on the device
+Bug fixed.
+
+** Upgrade of Chopstx
+We use Chopstx 1.3.
+
+
+* Major changes in Gnuk 1.2.2
+
+  Released 2016-10-15, by NIIBE Yutaka
+
+** Change of SELECT FILE behavior 
+Gnuk used to reply AID upon SELECT FILE command.  Now, to be compatible
+to original OpenPGP card, it returns nothing but status code of 9000.
+
+** Added feature of Factory Reset as compile time option
+Original OpenPGP card has the feature, and Gnuk is now configurable to
+support the feature.
+
+** Upgrade of Chopstx
+We use Chopstx 1.2.
+
+
+* Major changes in Gnuk 1.2.1
+
+  Released 2016-07-11, by NIIBE Yutaka
+
+** Upgrade of Chopstx
+We use Chopstx 1.1.

+somehow experimental, and it requires modern GnuPG 2.2 with libgcrypt
+1.7.0 or later.

 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
+card-edit/kdf-setup command.

-Key length of RSA
-=================
-
-In 2005, NIST (National Institute of Standards and Technology, USA)
-has issued the first revision of NIST Special Publication 800-57, 
-"Recommendation for Key Management".
-
-In 800-57, NIST advises that 1024-bit RSA keys will no longer be
-viable after 2010 and advises moving to 2048-bit RSA keys.  NIST
-advises that 2048-bit keys should be viable until 2030.
-
-As of 2010, GnuPG's default for generating RSA key is 2048-bit.
-
-Some people have preference on RSA 4096-bit keys, considering
-"longer is better".
-
-However, "longer is better" is not always true.  When it's long, it
-requires more computational resource, memory and storage, and it
-consumes more power for nomal usages.  These days, many people has
-enough computational resource, that would be true, but less is better
-for power consumption.
-
-For security, the key length is just a single factor.  We had and will have
-algorithm issues, too.  It is true that it's difficult to update
-our public keys, but this problem wouldn't be solved by just have
-longer keys.
-
-We deliberately support only RSA 2048-bit keys for Gnuk, considering
-device computation power and host software constraints.
-
-Thus, the key size is 2048-bit in the examples below.

-
-Note that the key on host PC is protected by passphrase (which
-is <PASSWORD-KEY-ON-PC> in the example above).  Using the key
-from the backup needs this passphrase.  It is common that
-people will forget passphrase for backup.  Never forget it.
-You have been warned.
-
-To make ASCII backup for private key,
-invokde GnuPG with ``--armor`` option and ``--export-secret-keys``
-specifying the key identifier. ::
-
-  $ gpg --armor --output <YOUR-SECRET>.asc --export-secret-keys <YOUR-KEY-ID>
-
-From the backup,
-we can recover privet key by invoking GnuPG with ``--import`` option. ::

+"Recommendation for Key Management".
+
+In 800-57, NIST advises that 1024-bit RSA keys will no longer be
+viable after 2010 and advises moving to 2048-bit RSA keys.  NIST
+advises that 2048-bit keys should be viable until 2030.
+
+As of 2016, GnuPG's default for generating RSA key is 2048-bit.
+
+Some people have preference on RSA 4096-bit keys, considering "longer is better".
+
+However, "longer is better" is not always true.  When it's long, it
+requires more computational resource, memory, and storage.  Further,
+it consumes more power for nomal usages.  These days, many people has
+enough computational resource, that would be true, but less is better
+for power consumption, isn't it?
+
+For security, the key length is just a single factor.  We had and will have
+algorithm issues, too.  It is true that it's difficult to update
+our public keys, but this problem wouldn't be solved by just having
+longer keys.
+
+We deliberately recommend use of RSA 2048-bit keys for Gnuk,
+considering device computation power and host software constraints.
+
+Thus, the key size is 2048-bit in the examples below.
+
+When/If your environment allows use of newer ECC keys, newer ECC keys are recommended.
+
+
+Generating RSA keys on host PC
+==============================
+
+Here is the example session to generate main key and a subkey for encryption.
+
+I invoke GnuPG with ``--quick-gen-key`` option. ::
+
+  $ gpg --quick-gen-key "Niibe Yutaka <gniibe@fsij.org>"
+  About to create a key for:
+      "Niibe Yutaka <gniibe@fsij.org>"
+
+  Continue? (Y/n) y
+
+It askes passphrase for this **key on host PC**.
+Note that this is a passphrase for the key on host PC.
+It is different thing to the passphrase of Gnuk Token.
+We enter two same inputs two times
+(once for passphrase input, and another for confirmation),
+<PASSWORD-KEY-ON-PC>.
+
+Then, GnuPG generate keys.  It takes some time.  ::
+  
+  We need to generate a lot of random bytes. It is a good idea to perform
+  some other action (type on the keyboard, move the mouse, utilize the
+  disks) during the prime generation; this gives the random number
+  generator a better chance to gain enough entropy.

+  sub   rsa2048 2016-06-20 []
+
+Done.
+
+Then, we create authentication subkey.
+Authentication subkey is not that common,
+but very useful (for SSH authentication).
+As it is not that common, we need ``--expert`` option for GnuPG. ::

+
+OK, we set the capability of ``Authenticate``.
+We enter ``q`` to finish setting capabilities. ::
+
+  Your selection? q
+
+GnuPG asks bitsize and expiration, we enter 2048 for bitsize and no expiration.
+Then, we confirm that we really create the key. ::
+
+  RSA keys may be between 1024 and 4096 bits long.
+  What keysize do you want? (2048) 
+  Requested keysize is 2048 bits
+  Please specify how long the key should be valid.

+
+Then, it askes the passphrase, it is the passphrase of **key on host PC**.
+It's the one we entered above as <PASSWORD-KEY-ON-PC>.
+
+Then, GnuPG generate the key. ::
+
+  We need to generate a lot of random bytes. It is a good idea to perform
+  some other action (type on the keyboard, move the mouse, utilize the
+  disks) during the prime generation; this gives the random number
+  generator a better chance to gain enough entropy.

+
+  gpg> save
+  $ 
+
+Now, we have three keys (one primary key for signature and certification,
+subkey for encryption, and another subkey for authentication).
+
+
+Publishing public key
+=====================
+
+We make a file for the public key by ``--export`` option of GnuPG. ::
+
+  $ gpg --armor --output <YOUR-KEY>.asc --export <YOUR-KEY-ID>
+
+We can publish the file by web server.  Or we can publish the key
+to a keyserver, by invoking GnuPG with ``--send-keys`` option.  ::
+
+  $ gpg --keyserver pool.sks-keyservers.net --send-keys <YOUR-KEY-ID>
+
+Here, pool.sks-keyservers.net is a keyserver, which is widely used.
+
+
+Backup the private key
+======================
+
+There are some ways to back up private key, such that backup .gnupg
+directory entirely, or use of paperkey, etc.
+Here, we describe backup by ASCII file.
+ASCII file is good, because it has less risk on transfer.
+Binary file has a risk to be modified on transfer.
+
+Note that the key on host PC is protected by passphrase (which
+is <PASSWORD-KEY-ON-PC> in the example above).  Using the key
+from the backup needs this passphrase.  It is common that
+people will forget passphrase for backup.  Never forget it.
+You have been warned.
+
+To make ASCII backup for private key,
+invokde GnuPG with ``--armor`` option and ``--export-secret-keys``
+specifying the key identifier. ::
+
+  $ gpg --armor --output <YOUR-SECRET>.asc --export-secret-keys <YOUR-KEY-ID>
+
+From the backup,
+we can recover privet key by invoking GnuPG with ``--import`` option. ::
+
+  $ gpg --import <YOUR-SECRET>.asc
+
+
+Generating ECC keys on host PC
+==============================
+
+Here is an example session log to create newer ECC keys.  You need
+libgcrypt 1.7 or newer and GnuPG 2.1.8 or newer.
+
+Next, we invoke gpg frontend with ``--expert`` and ``--full-gen-key`` option. ::
+
+    $ gpg --expert --full-gen-key
+    gpg (GnuPG) 2.1.13; Copyright (C) 2016 Free Software Foundation, Inc.
+    This is free software: you are free to change and redistribute it.
+    There is NO WARRANTY, to the extent permitted by law.
+
+Then, we input ``9`` to select ECC primary key and ECC encryption subkey. ::
+    
+    Please select what kind of key you want:
+       (1) RSA and RSA (default)
+       (2) DSA and Elgamal
+       (3) DSA (sign only)
+       (4) RSA (sign only)
+       (7) DSA (set your own capabilities)
+       (8) RSA (set your own capabilities)
+       (9) ECC and ECC
+      (10) ECC (sign only)
+      (11) ECC (set your own capabilities)
+    Your selection? 9
+
+Next is the important selection.  We input ``1`` to select "Curve25519". ::
+
+    Please select which elliptic curve you want:
+       (1) Curve 25519
+       (2) NIST P-256
+       (3) NIST P-384
+       (4) NIST P-521
+       (5) Brainpool P-256
+       (6) Brainpool P-384
+       (7) Brainpool P-512
+       (8) secp256k1
+    Your selection? 1
+
+You may see WARNING (it depends on version of GnuPG) and may been asked.  Since it is what you want, please answer with 'y'. ::
+
+    gpg: WARNING: Curve25519 is not yet part of the OpenPGP standard.
+    Use this curve anyway? (y/N) y
+
+It asks about expiration of key. ::
+
+    Please specify how long the key should be valid.
+             0 = key does not expire
+          <n>  = key expires in n days
+          <n>w = key expires in n weeks
+          <n>m = key expires in n months
+          <n>y = key expires in n years
+    Key is valid for? (0) 
+    Key does not expire at all
+    Is this correct? (y/N) y
+
+Then, it asks about a user ID. ::
+
+    GnuPG needs to construct a user ID to identify your key.
+    
+    Real name: Kunisada Chuji
+    Email address: chuji@gniibe.org
+    Comment: 
+    You selected this USER-ID:

+
+Lastly, it asks confirmation. ::

 The ``use-agent`` option is for GnuPG 1.4.x and it means using gpg-agent if available.
 If no option, GnuPG 1.4.x directly connects to Gnuk Token by itself, instead of through scdaemon.  When GnuPG 1.4.x tries to access Gnuk Token and scdaemon is running, there are conflicts.

 We recommend to specify the ``use-agent`` option for GnuPG 1.4.x to access Gnuk Token through gpg-agent and scdaemon.

Aurelien Jarno	6cbf5a4822	linker script: fix keystore_pool size Gnuk supports RSA keys up to 4096 bits. This require 1024 bytes of storage (p and q are 256 bytes, n is 512 bytes). The linker script should therefore reserve 1024 bytes per key instead of 512. In practice it's not an issue at all as all supported MCU have a page size bigger than 1024 bytes and Gnuk use one page per key.	2017-10-19 14:31:12 +09:00

This has been done in upstream commit a755ca1bbe, but somehow the generic version has been missed in gnuk's version.	2017-10-17 15:00:55 +09:00

Jeremy Drake	eea011fe70	Allow compile-time override of detected flash size. On the STM32F103C8, as used in the "blue pill" boards, it has been determined that, despite these only officially having 64KiB flash, it is possible to actually use 128KiB of flash. This commit allows for a preprocessor define STM32F103_OVERRIDE_FLASH_SIZE which, when set, is used as the size of flash in KiB instead of reading it from the FLASH_SIZE_REG.	2017-08-03 21:20:47 +09:00
