Description

chkey is used to change a user’s secure RPC public key and secret key pair. chkey prompts for the old secure-rpc password and verifies that it is correct by decrypting the secret key. If the user has not already keylogged in, chkey registers the secret key with the local keyserv(1M) daemon. If the secure-rpc password does not match the login password, chkey prompts for the login password. chkey uses the login password to encrypt the user’s secret Diffie-Hellman (192 bit) cryptographic key.

chkey ensures that the login password and the secure-rpc password are kept the same, thus enabling password shadowing, (see shadow(4) ).

The key pair can be stored in the /etc/publickey file, (see publickey(4) ), NIS publickey map or NIS+ cred.org_dir table. If a new secret key is generated, it will be registered with the local keyserv(1M) daemon.

If the source of the publickey is not specified with the -s option, chkey consults the publickey entry in the name service switch configuration file (see nsswitch.conf(4) ). If the publickey entry specifies one and only one source, then chkey will change the key in the specified name service. However, if multiple name services are listed, chkey can not decide which source to update and will display an error message. The user should specify the source explicitly with the -s option.

Non root users are not allowed to change their key pair in the files database.
