This is a logical fallacy. It is called circular reasoning. I need a key to decrypt a key. I still have to store that secondary key somewhere, or the system will have to regenerate it. Regenerate means I can see it in the source. Storage means it is a sitting duck, unencrypted.
If you agree it's a fallacy, then what were you suggesting with:
Quote:
...the half-keys should be encrypted - both on the user side and the system side.
Unless your point was simply that you shouldn't keep them around indefinitely in retrievable form -- and I don't. I don't encrypt them though, just delete them at regular intervals, as the session times out.

NAME
keylogin - decrypt and store secret key with keyserv SYNOPSIS
/usr/bin/keylogin [-r] DESCRIPTION
The keylogin command prompts for a password, and uses it to decrypt the user's secret key. The key may be found in the /etc/publickey file (see publickey(4)) or the NIS map ``publickey.byname'' or the NIS+ table ``cred.org_dir'' in the user's home domain. The sources and their lookup order are specified in the /etc/nsswitch.conf file. See nsswitch.conf(4). Once decrypted, the user's secret key is stored by the local key server process, keyserv(1M). This stored key is used when issuing requests to any secure RPC services, such as NFS or NIS+. The program keylogout(1) can be used to delete the key stored by keyserv . keylogin will fail if it cannot get the caller's key, or the password given is incorrect. For a new user or host, a new key can be added using newkey(1M), nisaddcred(1M), or nisclient(1M). If multiple authentication mechanisms are configured for the system, each of the configured mechanism's secret key will be decrypted and stored by keyserv(1M). See nisauthconf(1M) for information on configuring multiple authentication mechanisms. OPTIONS
-r Update the /etc/.rootkey file. This file holds the unencrypted secret key of the superuser. Only the superuser may use this option. It is used so that processes running as superuser can issue authenticated requests without requiring that the administra- tor explicitly run keylogin as superuser at system startup time. See keyserv(1M). The -r option should be used by the administra- tor when the host's entry in the publickey database has changed, and the /etc/.rootkey file has become out-of-date with respect to the actual key pair stored in the publickey database. The permissions on the /etc/.rootkey file are such that it may be read and written by the superuser but by no other user on the system. If multiple authentication mechanisms are configured for the system, each of the configured mechanism's secret keys will be stored in the /etc/.rootkey file. FILES
