NAME
     chkey - change user's secure RPC key pair

SYNOPSIS
     chkey [-p] [-s nis | files | ldap]
          [-m ]


DESCRIPTION
     chkey is used to change a user's secure RPC public  key  and
     secret  key pair. chkey prompts for the old secure-rpc pass-
     word and verifies that  it  is  correct  by  decrypting  the
     secret  key. If the user has not already used keylogin(1) to
     decrypt and store the secret  key  with  keyserv(1M),  chkey
     registers  the secret key with the local keyserv(1M) daemon.
     If the secure-rpc password does not match  the  login  pass-
     word,  chkey  prompts for the login password. chkey uses the
     login password to encrypt the user's  secret  Diffie-Hellman
     (192  bit)  cryptographic  key. chkey can also encrypt other
     Diffie-Hellman keys for  authentication  mechanisms  config-
     ured.


     chkey ensures that the login  password  and  the  secure-rpc
     password(s)  are  kept the same, thus enabling password sha-
     dowing. See shadow(4).


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


     Keys for specific mechanisms can be changed or  re-encrypted
     using the -m option followed by the authentication mechanism
     name. Multiple  -m options can be used to change one or more
     keys.


     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 mes-
     sage. The user should specify the source explicitly with the
     -s option.
