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.

And then, I was informed for this having many CVEs:

Well, mine is independent, and more easier to be attacked.Yutaka Niibe at 2020-10-02T01:46:05Z

Supporting Ed448 (GnuPG)
2020-06-24T01:21:24Z via Pumpa To: Public CC: Followers
I pushed the change to support Ed448 to GnuPG master:
https://dev.gnupg.org/rGa763bb2580b0d586a80b8ccd3654f41e49604f4fEd448 in libgcrypt

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)

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

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.salyavin likes this.
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 😃

Longan Nano comes with LCD display, which is connected through SPI.
I wrote a SPI driver for Chopstx.
This is an example.salyavin likes this.

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. :-)McClane likes this.

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

GnuPG 2.2.17 is out.
This includes a important change to access key retrieval from WKD (Web Key Discovery).

I'm back to Savannah, to update Japanese translation of www.gnu.org.
I found that it now supports Ed25519 SSH key, that's good for me (using Gnuk Token).I need a hole for the metal case

This is a pulseview window of sigrok.I needed to have a "look" at these signals to debug my smartcard reader.- D0 line is power supply of +3V3.
- D1 line is I/O.
- D2 line is RST.
- D3 line is CLK.
