In the process of using the mobile phone, some certificate-related errors can be found when installing the application. The concept of "mobile phone certificate" is introduced here, which can be understood as: a passport for software.

S60v3 has greatly improved its security, and has stricter regulations on third-party software. Part of the software involves the operation of mobile phone software and hardware security/personal information security, which has been specially restricted. For example, automatic startup of mobile phone is one of the restricted functions.

The main function of mobile phone certificate is to prevent malicious software. To realize these "specially restricted" functions, the application must obtain a "signature", that is, someone should be responsible for the security of this operation! A program without any signature cannot be installed and run.

Use mobile phone certificate:

Certificates are not used for installation, nor are they simply placed in any folder, nor are they imported into mobile phones (there is still a difference between importing root certificates mentioned in mobile phone system permissions and this). Certificates are used to sign software that needs to be "signed"

What is a signature? The so-called "signature" means that the certificate is packaged into sis software through the signature tool, and the role of the certificate is only to give the program certain rights. Regarding the signature tool, the following instructions are attached; Don't lose the certificate, put it in a storage medium that can be found at any time.

When downloading software in the forum, you can see the prompt that you need to sign your own name. As the name implies, software needs to be signed by itself. The signed program software can only be used on the mobile phone with this serial number, and other mobile phones cannot be used. Now the forum is doing the same batch of 1000 serial number * * one certificate.

Many well-known software, such as QQ and UC browser, can be installed directly without signature. In fact, it is not really unsigned, but the software development company has passed the Symbian verification and signed a general certificate for the software. It is not really unsigned, and a program without any signature cannot be installed and run.

Permission of mobile phone certificate:

As mentioned above, the role of a certificate is to give the program certain rights. The permissions of mobile phone certificates are also different. Beginners don't need to know what the authority is, they just need to know what kind of certificate they need.

5 permissions: You can find the 5 permissions universal certificate online, but the permissions are too low. If the software requires signature, then five permissions are generally not enough.

Permission 13: The same permission is too low to obtain and can be ignored.

17 permission: the 17 permission certificate applied by the forum can be used to sign and install most software. Generally speaking, the certificate refers to the authority certificate of 17, which is not universal. Please apply by yourself.

19 permission: actually, there is no 19 permission certificate; The BiNPDA certificate circulating on the Internet can achieve 19 permission signature by matching with the root certificate file, which is also a method of mobile phone decryption.

Validity period of mobile phone certificate:

The mobile phone certificate applied in the forum is valid for 3 years, and it doesn't matter if it expires. Expired certificates can also successfully sign the program. Only when installing the signature program, you need to adjust the date of the mobile phone to the validity period of the mobile phone certificate before you can install it, that is, the certificate can be reused indefinitely.

Application/use of mobile phone certificate: Please submit the mobile phone serial number to 165438+ every day, without any qualification, just leave the IMEI (press *#06# for standby), and the successfully registered IMEI can be used the next day, or you can go to/submit the mobile phone serial number and download the certificate.

After successfully applying for and downloading the certificate, you can use the signing tool to sign the software that needs to be signed. The following two tutorials have the same function. Choose one to learn and use.

Mobile phone certificate signing tutorial:/thread-2797537-1-1.html.

Programs that cannot be installed because of certificate restrictions can be installed after signing, which is actually quite easy. Want to know more about certificates, please see here:/thread-733801-1.html, and please go to the certificate consultation area: /forum- 194.

Other peripheral devices of mobile phone certificate:

I often have friends who send me messages asking me to help me testify, or I often have friends who send me messages saying that he wants to learn to testify, which is a bit funny. By the way, how to do the mobile phone certificate.

Take the 17 authority certificate made by the forum for machine friends as an example. If you want to make a certificate, you must first have a PID account authorized by Symbian, and then you can make a certificate for your mobile phone. The usage fee of this PID account is about $200 a year, which I believe ordinary people can't afford, so it can be seen that the forum has paid a lot for the machine friends.

In fact, PID account is provided for program developers, not for developers to test. Without a certificate, even software developers can't install software. In other words, the certificate made by the forum belongs to the developer certificate, so it is limited to a small number of mobile phones, which also ensures the security of mobile phones to some extent.

Introduction to mobile phone disconnection:
