https://idm.wikimedia.org/keymanagement/ should show full ssh public keys. Keys can be long so it is reasonable to show some shorthand version in the default list view, but it should be possible to view the entire key as recorded in the backing LDAP directory from the screen. Currently this seems only possible by clicking the slightly scary sounding "Suspend" button and looking at the confirmation screen.

See https://toolsadmin.wikimedia.org/profile/settings/ssh-keys/ as an example of showing a key's fingerprint by default with a small amount of css + javascript to display the full key.
