+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:
+
+```plaintext
+RWTJ8JZMFWhB2Ya9GyXbmOQKSxd/x57IV/oNo6/nl344CR1aqf/OgPXf
+```
+
+My new post-quantum SSH key fingerprint is:
+
+```plaintext
+SHA256:nickq1NBXN7qL2st6yfUcYgrhtqo13cl8ht/3FvtbJ4
+```
+
+You can verify this transition statement with my old Signify key like this:
+
+```sh
+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:
+
+```sh
+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
+```
