About the certificate: Significance: The mobile phone certificate can be understood as: the passport of the software.
Product Name: phone 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 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 will have functional limitations when installed, such as: Calden.
Function. The main thing is to prevent malware. In order for an application to implement these "specifically restricted" functions, 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**?
Certificates are not used to install, nor are they simply placed in a folder, they are used to sign 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 when you get it!
What is a signature?
"Signing" is the process of packaging a certificate into a program that needs to be signed. This process requires a special signature tool (software).
What is Self-Signed Program Software?
As the name suggests, self-signature means that you need to sign by yourself, and this self-signed program software can only be used for the mobile phone with the serial number, and other mobile phones cannot be used. (Now the forum produces a certificate for the same batch of 1000 serial numbers).
Certificate expiration: The certificate expired mentioned here, not the mobile phone prompted the certificate expired when installing the program, but the expiration of the cer certificate file you applied for, in fact, it doesn't matter if it expires, the expired certificate can also be successfully signed on the program, but when installing this signed program, you need to adjust the time of your hand to the validity period of the cer certificate file to install it.
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 a 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 in your hands.
Installed in the machine.
In short, a certificate scheme is a measure adopted to address security issues, and its role is mainly twofold:
1。Prove the legitimacy of the software. 2。Allow the software to start autonomously.

Li Shangyin's Untitled translation is: Last night the stars were shining, the wind was like water, I wandered to the west of the painting building, and all I thought about was you who lived in the east of Guitang. Although we are close at hand, it is as if we are separated by the end of the world; I hate myself, I don't have wings like a colorful phoenix to fly freely with you, and I can be glad that you and I are heart-to-heart with each other, and we know each other. 」
