In this dialog it’s
about the character set to enter and read in key information. To get the
possibility to enter all possible characters apart from the “normal” character
set (ASCII character) which can be entered by the keyboard, you can choose
another character set (hexadecimal character), so any two characters of which
are combined to one key character by the program. With this character set key
characters can be generated which can not or only laboriously generated in a
direct way by keyboard buttons.
Using the checkbox field on the right above the key
input field, you can decide if you want to enter or read key information direct
or using a dataset in hexadecimal form or via ASCII characters. In dialogue
entering a direct key you have the possibility to change the character set at
any time i.e. from ASCII characters to hexadecimal characters and vice versa.
With it ASCII characters automatically are expanded to its hexadecimal values
or in opposite direction hexadecimal values are condensed to ASCII characters.
The latter possibility only exists if there is no character value 00hex in the key
(internally interpreted as the end of a string).
