what does backup shsh mean?
the full name of SHSH is Signature HaSH blobs, and the Chinese name is signature certificate. When we need to restore the mobile phone to the system, Apple's mobile phone ear server will generate a shsh signature according to each of our mobile phones, and use this shsh signature to authenticate. Only after the authentication is passed can we restore it. Moreover, the shsh file is as unique as the serial number, because it will be arranged according to the factory code of each mobile phone, that is, you can't use someone else's shsh to operate your own mobile phone. Backing up shsh means backing up the signature file of shsh, which is convenient for verifying the system recovery later. If you don't back up the related shsh file, you won't be able to pass the verification of Apple server, and you won't be able to recover the old system.
What's the use of backing up shsh
Because the shsh file is on the server of Apple's mobile phone, whenever a new firmware is released, Apple's mobile phone will shut down the provision of the previous version of shsh file, so if we want a perfect jailbreak, we must downgrade it, and we must also have the corresponding version of shsh file. At this time, it is particularly important to back up shsh. To put it simply, backing up shsh is a kind of authentication certificate that can help us to brush back the old version of the system in the future. If we don't back up, once Apple closes the previous version of shsh file, we will not be able to restore to the previous old version of the system if we make a mistake in jailbreaking or upgrade the new version of the system later.
