+# cryptography is pinned to 43.0.3 because sshkey-tools 0.11.3 (SSH CA cert
+# signing) requires cryptography <44. The two findings below are only fixed in
+# cryptography >=44/48, which we cannot adopt until sshkey-tools relaxes its pin.

+# Action to remove: bump sshkey-tools to a release allowing cryptography>=48,
+#                   then set cryptography>=48.0.1 and delete these lines.
