User's Guide to MPE/iX Security

Lockwords 

Lockwords act as passwords for files, providing additional security
beyond those provided by capabilities and file access restrictions.  The
creator of a file can assign a lockword with the FILE, BUILD, or RENAME
command or with the FOPEN intrinsic.

If a file has a lockword, you must supply it before you can access that
file.  If you are the account manager (with AM capability), you can
display file lockwords with the LISTFILE or LISTF command, file lockwords
with the LISTFILE or LISTF commands, documented in MPE/iX Commands 
Reference Manual Volumes 1 and 2 (32650-90003 and 32650-90364).


NOTE  Lockwords are not encrypted and a user with SM or AM capabilities
      can view them.


Figure 4-1  illustrates how lockwords and passwords work at different
levels.

NOTE  Lockwords should not be used on files that have ACDs attached to
      them.
