Generate passphrase

[anstylian]

The suggested command for generating a passphrase is not working for me. Can you test it?

export CERTIFY_PASS=$(LC_ALL=C tr -dc 'A-Z1-9' < /dev/urandom | \
  tr -d "1IOS5U" | fold -w 30 | sed "-es/./ /"{1..26..5} | \
  cut -c2- | tr " " "-" | head -1) ; printf "\n$CERTIFY_PASS\n\n"

It fails with this error sed: -e expression #1, char 7: unknown option to 's'

As I understand the result should have this format:
1234-12345-12345-12345-12345-12345

To archive the about I have used this command

export CERTIFY_PASS=$(LC_ALL=C tr -dc 'A-Z1-9' < /dev/urandom \
| tr -d "1IOS5U" | fold -w 30 | sed 's/.\{5\}/& /g' | cut -c2- | tr " " "-" |\
 head -1 | sed 's/-$//') ; printf "\n$CERTIFY_PASS\n\n"

I am opening a PR with the above in case a change is needed.

Which platform does this happen on?

I have taken the nixos image you provided and flashed it on sd card for the Raspberry Pi 3.

I have run your command now, at my desktop, and I see that works fine.
Also, what I wrote above is wrong:

As I understand the result should have this format:
1234-12345-12345-12345-12345-12345

Now I see that the correct format is '1234-1234-1234-1234-1234-1234', so the comment above should be adjusted to this:

export CERTIFY_PASS=$(LC_ALL=C tr -dc 'A-Z1-9' < /dev/urandom | \
tr -d "1IOS5U" | fold -w 24 | sed 's/.\{4\}/& /g'  | tr " " "-" | \
head -1 | sed 's/-$//') ; printf "\n$CERTIFY_PASS\n\n"

@justuswilhelm @motiejus would you mind validating the passphrase commands on nixOS if you have a chance - thank you!

[justuswilhelm]

The export CERTIFYPASS=... command specified in the README.md works well, see the attached screenshot (tested in QEMU)

QEMU is run with

nix run ".#nixosConfigurations.yubikeyLive.x86_64-linux.config.system.build.vm"

Can I help by running anything else?
