malicious software
. In order to realize these "specially restricted" functions, the application must obtain a "signature". In other words, someone should be responsible for the safety of this operation! A program without any signature cannot be installed and run.
Where should I put the obtained "certificate"?
In fact, certificates are not simply placed in any folder. Certificates are used to sign software that needs to be "signed". Certificates are not used directly, but packaged into sis software through a special program. The role of a certificate is only to give the program certain permissions. Don't lose the certificate you got, because a certificate is valid for 6 months and you can sign a lot of software. If the certificate expires, you can apply for a new certificate, or you can adjust the time of the mobile phone before installation. Just adjust the time to the validity period of the certificate.

There will be signed and unsigned versions. For unsigned software, we can apply for a certificate ourselves and make software for our own machine.
Saipan
The provided SIGN tool makes the key file of your mobile phone and writes it into the software to be installed, and then the software can only be installed in your mobile phone.
In short, the certificate mechanism is a measure to solve security problems, and its functions are mainly two points: 1. Prove the legitimacy of the software. 2。 Allow the software to start itself.
