Revoka
Iċ-ċwievet SSH m’għandhomx ċertifikat ta’ revoka. Biex tirrevoka ċavetta, neħħiha minn authorized_keys jew niżżilha f’lista ta’ revoka taċ-ċwievet OpenSSH (KRL, maħluqa b’ssh-keygen -k) li s-server jaqra permezz ta’ RevokedKeys.
Ivverifika l-firma
Issejvja ċ-ċavetta pubblika u l-firma ħdejn test_1MB.bin, oħloq fajl allowed_signers u ħaddem 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
