GnuPG 2.3.1 is released
2021-04-21T00:23:02Z via Pumpa To: Public CC: Followers
Bug fixing (mostly for build) release. It's a worth try.
Scorpio shared this.
Libgcrypt 1.9.3 is released
2021-04-19T23:46:45Z via Pumpa To: Public CC: Followers
It would be good if this was the 1.9.0. I mean, there are more fixes for regressions (than we had expected).

Good things are the build process has been improved.
Ploting X448
2021-04-12T02:08:16Z via Pumpa To: Public CC: Followers
Green plots are the first 200 points of X448.
Green star is the generator.
GnuPG 2.3.0 released
2021-04-07T23:54:08Z via Pumpa To: Public CC: Followers
It comes with Ed448/X448 support.
Sway
2021-04-06T05:45:29Z via Pumpa To: Public CC: Followers
I start using Sway to test Wayland on this machine.
It seems that input method support is not that mature in the protocol.

Thus, I fixed my implementation (of Emacs Lisp) for Japanese input.
Ed448 for Gnuk
2021-03-17T23:50:52Z via Pumpa To: Public CC: Followers
Running 100 iterations, signing on FST-01 (Cortex-M3 @ 72MHz), it's like:

real 0m15.929s
user 0m0.973s
sys 0m0.262s

Yes, generated signature is good:
~$ gpg --verify /tmp/a1.asc /etc/motd
gpg: NOTE: THIS IS A DEVELOPMENT VERSION!
gpg: It is only intended for test purposes and should NOT be
gpg: used in a production environment or with production keys!
gpg: Signature made Thu Mar 18 08:47:45 2021 JST
gpg: using EDDSA key 91B78334699E9155A9E0651CBE352A1DCF455BFF
gpg: Good signature from "Kunisada Chu " [ultimate]
X448 for Gnuk
2021-03-09T05:41:52Z via Pumpa To: Public CC: Followers
Running 100 iterations, decrypting on FST-01G (Cortex-M3 @ 72MHz), it's like:
```
gpg: encrypted with cv448 key, ID F6FA616F8E4378B9, created 2021-03-09
      "Kunisada Chu <chuji@gniibe.org>"

real    0m34.189s
user    0m2.512s
sys 0m0.387s
gniibe@iwagami:~/work/gnuk/gnuk/src$ 
```
That is, 0.34189 second for a single decryption process.

It's good enough for me.
Gnuk 1.2.17
2021-02-26T05:17:30Z via Pumpa To: Public CC: Followers
Mainly for GNU/Linux emulation, new Gnuk is out.

sub and subs instruction (pre-UAL syntax, UAL syntax)
2021-02-25T03:12:26Z via Pumpa To: Public CC: Followers
I didn't know well about two different syntax in ARM assembler.

For UAL syntax (newer, which is usually used), it requires an explicit "s" suffix to specify flags being set, while pre-UAL syntax (older, which is used for Cortex-M0) assumes that implicitly.

In GCC, we have -masm-syntax-unified option.
libgcrypt 1.9.2 released
2021-02-17T23:39:28Z via Pumpa To: Public CC: Followers
Well, 1.9.0 had point-zero release problem (= no one tests well until its release).

Now, it has support of Ed448/X448 curves.

Enjoy,

GD32VF103 and its possible use for Gnuk
2020-09-30T23:59:47Z via Pumpa To: Public CC: Followers
GD32VF103, which comes with RISC-V core, is cheap and fast.

I ported Chopstx to GD32VF103, and am considering if it's good to port Gnuk.

Last month, when I found riscv-openocd merged the support of GD32VF103, I tried to use the debugger interface.

And... for my version (which I bought from Seeed), the Longan Nano, I can access its flash ROM content.
If my analysys is correct, it's a kind of matter for CVE, I suppose.

With help of my Chinese friends, I try to contact the vendor.

Happy Chinese Holiday Season!

And then, I was informed for this having many CVEs:
https://github.com/JohannesObermaier/f103-analysis/

Well, mine is independent, and more easier to be attacked.

Supporting Ed448 (GnuPG)
2020-06-24T01:21:24Z via Pumpa To: Public CC: Followers
I pushed the change to support Ed448 to GnuPG master:

Ed448 in libgcrypt
2020-06-10T23:59:57Z via Pumpa To: Public CC: Followers
X448 feature has been pushed to GnuPG master.

Now, I'm adding the support of Ed448 to libgcrypt so that it will be also supported by GnuPG.
Supporting X448 (GnuPG)
2020-06-10T23:58:44Z via Pumpa To: Public CC: Followers
I pushed the change to support X448 to GnuPG master.
UI (displaying the name of algo, selecting it from tty or command line) needs some more changes, though.
Bouncing GnuPG Logo
2019-12-26T23:33:30Z via Identi.ca Web To: Public CC: Followers
It's running on the Longan-Nano board with RISC-V MCU named GD32VF103 (Bumblebee core).

I took a video, but I don't know how we can share a video with free software friendly way.
So, it's an image only for now.

Just for the record, you can upload videos here, to Pump.io, with a client capable of it, like Dianara.

And there's always a Mediagoblin or Nextcloud instance 😃

"FSIJ" logo on 160x80 screen by RISC-V MCU
2019-12-01T23:49:16Z via Identi.ca Web To: Public CC: Followers
Longan Nano comes with LCD display, which is connected through SPI.
I wrote a SPI driver for Chopstx.
This is an example.

Last week, I renewed IEEE membership, and got a sticker saying "KEEP CALM I'M IEEE MEMBER".

Then, yesterday, I received FSF Bulletin. #fsfbulletin
It was sent on November 11th, the one of binary days. :-)

Chopstx is running on RISC-V MCU now.
I got the board named "Longan-nano", which uses GD32VF103.

With Migen, I wrote a SHA256 module.
