chkey(1)						      General Commands Manual							  chkey(1)

NAME

       chkey - change user's secure RPC key pair

SYNOPSIS

       [ ] [

DESCRIPTION

       is used to change a user's secure RPC public key and secret key pair.  prompts for the old secure-rpc password and verifies that it is cor-
       rect by decrypting the secret key.

       If the user has not already used to decrypt and store the secret key with registers the secret key with the local daemon.  If  the  secure-
       rpc  password  does  not  match	the  login password, prompts for the login password.  uses the login password to encrypt the user's secret
       Diffie-Hellman (192 bit) cryptographic key.

       ensures that the login password and the secure-rpc password are kept the same.

       The key pair can be stored in the file (see publickey(4)), the NIS map, or entries in the LDAP directory.  If a new secret  key	is  gener-
       ated, it will be registered with the local daemon.

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

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

   Options
       Re-encrypt the existing secret key with the user's
		   login password.

       Update the  NIS database.

       Update the  database.

       Update the  LDAP database.

WARNINGS

       HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is supported.  LDAP is the recommended replacement for NIS+.  HP fully supports
       the industry standard naming services based on LDAP.
