6.2.3 Interaction of Encryption Screen Controls
(1) Un-checking the “Enable Security” checkbox causes encryption to be disabled,
and causes all other screen controls (default key, keys and lengths) to become
disabled.
(2) Upon initial display of the Encryption screen, previously entered key values will
not be displayed. Each hex digit in these keys will be displayed as an asterisk
(*) character.
(3) Any modification to a key that is displayed as asterisk characters will cause the
key value to be erased. The new key must be entered in its entirety.
(4) Keys are restricted to contain only hex digits (0-9,A-F). The edit control for
each key will ignore entry of any non-hex digits. Digits may be upper or lower
case.
(5) Each key value is restricted to the length specified by the list control to its right.
(6) If a key has been entered (or partially entered), and the user changes its length
selection, the key will be truncated if necessary. For example, if the user has
entered 18 hex digits for Key 1, and then the user selects “10 Hex Digits” in its
corresponding length drop-list, then the last 8 digits of the key will be erased.
(7) If the user changes the key length selection for a key that is displayed as
asterisks, then the key value will be cleared, as described in (3) above.
6.2.4 Encryption Screen Input Validation
An error message is displayed, and the user is prevented from leaving the
Encryption screen (except via Cancel button), under the following conditions:
(1) Security is enabled, and no encryption key has been specified.
(2) The “Default Key to Use” selection is a key that has not been entered.
(3) The length of one of the non-blank encryption keys does not match the
corresponding key length specified.
