Are the old datasheets for HSM V1 , Pro V1 etc. anywhere available ? As I still have these keys and want to use them e.g. with RaspBerryPi, sometimes it could be helpfull to understand which Curve is not supported
I do not have fact sheet, but for now specification should answer your question as well. Nitrokey Pro v1 is using OpenPGP 2.x smart card. The exact version of the smart card is shown e.g. in the GnuPG smart card details screen. It’s specification could be found e.g. here: https://gnupg.org/ftp/specs/ - for v2.2 it would be https://gnupg.org/ftp/specs/OpenPGP-smart-card-application-2.2.pdf. Pro v2 has OpenPGP v3.3.
As for HSM v1, it is using HSM 2.x smart card. I do not remember right now, where details of it could found.
I tried to improve the FAQ a bit. You may have a look if I missed something. I was not sure about HSM though. Is the part below the table actually accurate for the HSM 1?
I can’t tell if it is accurate for HSM v1, but if, I would also put it into a column. Much faster to identify, that RSA4096 is not supported. In generic I think it is a good idea as you also have then a comparision between the keys. But how many keys are stored is not visible (e.g. HSM 2 stores much more )
Therefore I still believe publishing the former datasheets could be a benefit. You might need to watermark it to prevent wrong impressions in case somebody is sending them around.
Now the factsheets of our previous models’ version 1 are available here:
Nitrokey Pro 1 (German, English), Nitrokey HSM 1 (German, English), Nitrokey Storage 1 (German, English)
