Meaning: mobile phone certificate can be understood as: a pass for software.
English name: Phone
certificate
You need to apply for a certificate through the SYMBIAN website, and it corresponds to the IMEI number of the mobile phone one by one. This is why we need to apply for a permit. Need to be reminded that the certificate does not correspond to a certain software, but has a validity period (generally, the free application is half a year, and it is three years from 12, 12), and it can be used during the validity period, no matter what software is signed. Therefore, the certificate is not one-off. Please take care of your certificate.
S60
The third edition has greatly improved the security, and has stricter regulations on the installation and operation of third-party software in the system. Special restrictions are imposed on the operation of some software related to mobile phone hardware and software/personal information security (for example, automatic startup of mobile phone startup is one of the restricted functions).
Some software will have functional restrictions after installation, such as incoming calls.
function
Mainly to prevent 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 certificate I got?
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 3 years 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.
Usually downloaded mobile phone software has a signed version and an unsigned version. For unsigned software, we can apply for a certificate to make software for our machine, make the key file of our mobile phone through the sign tool provided by Saipan, and then write 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.

Not suitable for free users who need certificate signature like us.
They focus on developing software for developers, and then sign it uniformly to realize the use of the software.
For example, Tencent's QQ and Baiyue are both large regular software vendors.
Secondly, the maintenance of the server.
Is to retaliate against software developers for pushing their own software onto the network without their own software signatures.
Now only the publisher certificate (TC
Publisher
ID) make a certificate.
And the issuer certificate (TC
Publisher
ID) can also be explained in this way.
The function of this ID is to let developers make a universal signature for the software.
In order to get Saipan certification.
Only certified software can be used.
If software companies and cracking institutions have such accounts.
So the software we use doesn't need to be signed.
And the certificate we need and have now is actually born for testing software.

We don't have to place too much hope on Saipan.
It is very likely that you will not be able to apply for a free account in the future.
Moreover, we have to wait for the developer of the software to make a general signature for the software before using it.
