     CHANGELOGIN(8)                                     CHANGELOGIN(8)

     NAME
          changelogin - create/update the password file

     SYNOPSIS
          changelogin name

     DESCRIPTION
          Changelogin helps to administer a password file
          /keydb/password, a requirement of `signer' servers (see
          signer(8)). If a password file entry for name exists, it is
          modified; otherwise, a new entry is created.

          The user is prompted for the following items:

          password
               A string at least 7 characters in length. The SHA
               digest of the entered string is stored in the password
               file. See keyring-sha(2). By default, the password for
               an existing entry is unchanged.

          expiration date
               An expiration time in the format DDMMYYYY. The user
               input is checked for valid day, month, and year; more-
               over, the new date must be later than the current time.
               By default, the current value, if any, is unchanged for
               an existing entry and one year from the current time
               for a new entry.

          free form info
               Arbitrary administrative information.

          The length of each value is subject to the size limitations
          defined by the Password module; see security-password(2).

          Note that the password expiration date is also used as the
          default expiration date for any certificate later produced;
          see getauthinfo(8).

     FILES
          /keydb/password  where password entries are stored
