Encryption and decryption

To provide optimal data security, the QuickHMI file interfaces are equipped with optional encryption. Encryption is carried out directly if you have set up the

necessary settings within the data sources.


Please note: You must assign a password for encryption. Please keep this password up! If it is lost, the encrypted files can no longer be opened

We canĀ“t help in this case. The encryption routines require CPU resources! Plan slightly higher computing power. Especially when you very many variables are changed in very

short intervals. However, you can test the load in the editor during the runtime mode.


Your QuickHMI system includes a command line program for encryption and decryption. You can find it under [QuickHMI-Home] /qhmisecu.exe within the editor or server installation.


You can carry out the following actions:


1 Log files in logx-format or decrypt image files in the datx format


To do this, open the program qhmisecu.exe with the following parameters:

qhmisecu.exe -d <source file> <target file> <your password>

The decrypted file will be created.




2 Decode image files in xml format

       
Open the program qhmisecu.exe with the following parameters:

qhmisecu.exe -x <source file> <target file> <your password>

The decrypted file will be created.
