Explanation of Signature and Certificate.

The third version of S60 has made significant security improvements, with stricter regulations on third-party software installed and running in the system. Some operations involving the software and hardware security of mobile phones, personal information security, etc., have been specially restricted (for example, automatic start with the boot of the mobile phone is one of the restricted functions). The application wants to implement these"It is specially restricted"must be "signed".

In other words, someone has to be responsible for the safety of this operation! Programs that are not signed cannot be installed and run.

Sign: The use of a special tool to write the content of the certificate to a specific field of the application, indicating that the software has passed the signer's review. The signatory is responsible for the security of the software.

What we call "self-signing" is actually using this method, to put it bluntly, you say that you are developing software, you provide the IMEI code of your test machine, and Symbian issues you a "development certificate", and you sign your "test software" with this certificate. You yourself are responsible for your own "development behavior"! So much for.

In addition, the development certificate is valid for three years from the date of issue. However, there is no limit to the time limit for the use of the signed program (after the certificate expires, it can be installed by modifying the date of the mobile phone system, and it can be modified back after installation).

It only exists on S60 3rd Edition, 5th Edition and Symbian 3 smartphones, because of system reasons, they cannot install mobile phone software at will, and they need to sign the software with a certificate before they can install it. Certificates are like passports to software.

The third version of S60 has made significant improvements in security, and has stricter regulations on third-party software installed and running in the system. Some software involving mobile phone software and hardware security, personal information security and other aspects of the operation has been specially restricted (for example, automatic start with the mobile phone boot is one of the restricted functions).

Some software installations will have functional limitations, such as: incoming calls, hail fast.

Function. The main thing is to prevent malware. In order for an application to implement these "specifically source-restricted and regulated" features, it must be "signed". In other words, someone has to be responsible for the safety of this operation! Programs that are not signed cannot be installed and run.

The "certificate" you get is put on**?

In fact, the certificate is not simply placed in a folder, the certificate is used to sign the software that needs to be "signed". Certificates are not used directly, they are packaged into the SIS software through a special program. The purpose of a certificate is simply to give a certain amount of authority to the program.

Don't lose your certificate, because a certificate is valid for 6 months and can be used to sign a lot of software. If the certificate expires, you can apply for a new certificate, or you can adjust the time of your phone when you install it. The time can be adjusted to the validity period of the certificate.

Usually we have the first mobile phone software will have a signed version and an unsigned version, for the unsigned software, we can apply for a certificate to make the software for their own machine, through the sign tool provided by Symbian to make their own mobile phone key file and then write it into the software to be installed, and then this software can only be installed in your mobile phone.

In short, a certificate mechanism is a measure used to address security issues, and its role is mainly two:1. Prove the legitimacy of the software. 2。Allow the software to start autonomously.

Now individuals can't do certificates. You can go to the major mobile forums to apply. For example, Saipan.

The certificate is equivalent to giving a black account an ID card!
