Revocation
SSH keys have no revocation certificate. To withdraw a key, remove it from authorized_keys, or list it in an OpenSSH key revocation list (KRL, created with ssh-keygen -k) that the server reads through RevokedKeys.
Verify the signature
Save the public key and the signature next to test_1MB.bin, create an allowed_signers file and run 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
