Revoca
Le chiavi SSH non hanno un certificato di revoca. Per revocare una chiave, rimuovila da authorized_keys oppure inseriscila in un elenco di revoca delle chiavi OpenSSH (KRL, creato con ssh-keygen -k) che il server legge tramite RevokedKeys.
Verifica la firma
Salva la chiave pubblica e la firma accanto a test_1MB.bin, crea un file allowed_signers ed esegui ssh-keygen:
echo "example@ch-j $(cat id_ecdsa.pub)" > allowed_signers
ssh-keygen -Y verify -f allowed_signers -I example@ch-j -n file -s test_1MB.bin.sig < test_1MB.bin
