Statement of Signify Key Transition

To replace my Signify key, I have set up a new post-quantum SSH key.

This message is signed by both keys to certify the transition.

My old Signify key is:

RWTJ8JZMFWhB2Ya9GyXbmOQKSxd/x57IV/oNo6/nl344CR1aqf/OgPXf

My new post-quantum SSH key fingerprint is:

SHA256:nickq1NBXN7qL2st6yfUcYgrhtqo13cl8ht/3FvtbJ4

You can verify this transition statement with my old Signify key like this:

signify -V -p signify.pub -m signify-pq-ssh-transition-statement.txt -x signify-pq-ssh-transition-statement-signify.sig

You can verify this transition statement with my new post-quantum SSH key like this:

echo "nicholas $(cat signing-key_mldsa44_ed25519.pub)" > allowed_signers
ssh-keygen -Y verify -f allowed_signers -I "nicholas" -n journal -s signify-pq-ssh-transition-statement-pq-ssh.sig < signify-pq-ssh-transition-statement.txt

• signify.pub
