No.
I asked in case you'd be interested in more in-depth info. 👍
I got the basics set up. Not a functioning client yet. Will probably only be a minimal client to prove that everything works as expected. Device program-binary should do what's necessary but not fully tested yet. Then see where we go from there.
Interested to see how it works out for you.
😂😂😂 just testing with sending a 10 MiB message to the device for signing. With this device, probably in part because it's a fairly new idea/experiment, transfer is rather slow. It took 28 minutes. 😋
Of course, small messages of few KiB are fast. (seconds)
This #nostr note is posted from a small test application and signed with a key that is internal to the #security device.
Ironically, I have no access to this key, which is deterministically generated within the device, so with the next changes to the firmware-binary I'm going to lose access to this key, .. at least when I use the updated program-binary.
There are multiple modes of operation. nostr:nevent1qqs99ehnglvqm7zjp4jt0g2x803s3sl0cxc5ejlrgps0jxqrlx4d0yspz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsygz2plnksne0pxs73kj6a4q03a044z4ncpunun8eg4ryjl233jpwsvpsgqqqqqqs4lrtxf
You have a device already?
You can buy a general purpose "security device", currently a sort of early experiment, IIUC. (See https://tillitis.se/ ) It can load small programs. I'm writing such a program.
I'm not claiming this device is perfect, but it allows for many solutions like this one. (I'm not associated with them. Just playing around with the device.)
