Unlock protected blocks in Tia Portal v13

[kromp]

Hi,
Can someone tell me how to unlock OB1 in Tia?
It is asking me a password in one project that I have but I do not have it..
Please help me

It seems impossible. As Siemens uses aes encryption, program will be only decoded in real PLC.

And decode in a PLC-Simulation ?

I do not know about TIA, as I do not encrypt my program. But für Step7 block privacy, programs are NOT decoded in plcsim.
So I do not believe TIA Portal plcsim will decode the program.

IF program save in internal storage, you can find password and upload project via read EEPROM.
