Since the feature in version 1.19b you can show the plain for a given CW and 08h-Crypt8, but not for other playload sizes.
That's because for the decryption the complete crypt is needed and not only the first 8 crypted bytes of the crypt.
For 08h-Crypt8 this works because the complete crypt is also only 8 bytes long.
But in the new version 1.19f the plain of any payload size can be shown.
It has an additionally input field, the TS source file where the crypt8 was found.
It takes your Crypt8 input and search this Crypt8 in the TS source file.
After the tool has found it it copies the full crypt from the payload.
Then it decrypts the crypt value and shows the plain value.
So if you have found the CW (e.g. via the RBT tool from B8h-Crypt8), and this PID have also many other Crypt8 values from other payload sizes (e.g. A0h-Crypt8) you can use this new function to show the corresponding plain value.
Activation of the testing dialog:
- press <Ctrl> + t
- "Enter test number" will be shown
- for decryption of Crypt8 of any payload sizes enter the following number: 54813
- the testing dialog will be shown
- fill the input fields and press the start button
- Plain will be shown
