This statement is signed with the Ed25519 key at
https://piotrschumann.com/identity.pub (OpenSSH SSHSIG, namespace piotrschumann.com).

Verify:
  curl -s -O https://piotrschumann.com/identity.txt \
       -O https://piotrschumann.com/identity.txt.sig \
       -O https://piotrschumann.com/identity.pub
  echo "hello@piotrschumann.com $(cat identity.pub)" > allowed_signers
  ssh-keygen -Y verify -f allowed_signers -I hello@piotrschumann.com \
    -n piotrschumann.com -s identity.txt.sig < identity.txt

Recompute the signed Cases-Root from the published case texts:
  curl -s -O https://piotrschumann.com/cases.json
  node -e 'const c=require("crypto"),d=require("./cases.json"),H=b=>c.createHash("sha256").update(b).digest(),l=d.cases.map(x=>H(x.canonical)),r=H(Buffer.concat([H(Buffer.concat([l[0],l[1]])),H(Buffer.concat([l[2],l[3]]))]));console.log("sha256:"+r.toString("hex"))'
  # must print the Cases-Root line above
