- FREEZE Jeff Prosise
- Command l986/No. 22
-
- ______________________________________________________
-
- Purpose: Ensures confidentiality of in-memory data
- when it is necessary to leave a PC running
- without storing the data to a removable
- medium or encrypting it. FREEZE temporarily
- suspends program operation, blanks the
- screen, and disables the Ctrl-Alt-Del reboot
- sequence until a user-entered password (up to
- 64 characters) is re-entered.
-
- Format: [filespec]FREEZE
-
- Remarks: FREEZE is a memory-resident utility, normally
- loaded by an AUTOEXEC.BAT file. After
- loading, the machine is "locked" by pressing
- Alt-NumLock and then entering the passphrase
- of choice. The passphrase may include any
- characters except Esc and Enter. Pressing
- the Esc key aborts password entry, and
- pressing Enter initiates the lockdown.
-
- The Backspace key may be used to correct
- incidental mistakes, but care must be
- exercised, as the characters are not echoed
- on the screen during entry. To unlock the
- machine, simply re-enter the same password
- and press Enter. Again, the Backspace and
- Esc keys can be used to correct or abort
- password entry.
-
- Notes:
-
- 1. The password is never stored and may be
- changed each time FREEZE is invoked with
- Alt-Numlock. If an attempt is made to
- load FREEZE.COM more than once, an error
- message will result.
-
- 2. While FREEZE is believed compatible with
- most other memory-resident programs,
- because of the importance of data with
- which it is expected to be used, it
- should be thoroughly checked out in your
- specific configuration. In particular,
- FREEZE should be loaded before SideKick.
