To put it simply, it is the verification method that Sony added to the PS3/PSP host. Sony officially needs to add a signature number to every new game launched in the PSN online store, so that the PSP host can pass the verification, and players can play the game directly on the official system after downloading the game in the PSN online store. Because the hacker found the key and deciphered its algorithm, according to the key algorithm, the hacker can directly add a signature to the homemade software, which can be directly verified by the PSP host and played on the official system, just like the official release.

The first self-signed software reflection has been released.

At present, this software has no practical function, but more significance is display. Through the demonstration video, we can see that PSPgo host is the official system of 6.20 after shutdown, but the current 620 cracking program does not support shutdown, so the homemade software in this video runs directly through the official system. Similarly, if the ISO game can be signed, it can be run directly under the official system without any cracking!

To put it bluntly, with digital signature, you can play any game directly for free without frequent brushing.

It is good for us players to expect the official system to collapse completely, but it is a tragedy for Sony.

Cracking can prevent the natural monopoly of the industry and enable enterprises with low technical level to survive, so there is nothing to feel guilty about correctly treating cracking, let alone grievances.
