Revogação

As chaves SSH não têm certificado de revogação. Para revogar uma chave, remova-a de authorized_keys ou inclua-a numa lista de revogação de chaves do OpenSSH (KRL, criada com ssh-keygen -k) que o servidor lê através de RevokedKeys.

Verificar a assinatura

Guarde a chave pública e a assinatura junto de test_1MB.bin, crie um ficheiro allowed_signers e execute ssh-keygen:

echo "example@ch-j $(cat id_dsa.pub)" > allowed_signers
ssh-keygen -Y verify -f allowed_signers -I example@ch-j -n file -s test_1MB.bin.sig < test_1MB.bin
