In an Android system, all applications installed to the system must have a digital certificate that identifies the author of the application and establishes a trust relationship between the applications, if a permission ProtectionLevel is signature, Then only applications that have the same digital certificate as the program where the permission resides can get that permission. Android uses a Java digital certificate-related mechanism to give the APK

Specific production process: Preparation Tool: Figure 00 1. Sign a name first Really need to sign a larger name, and it is best to use marker (Mark pen) to write, so that the name of the line more clearly visible. 2. Take your signature. Take your signature with your camera and try to avoid a distortion of the lens (try to use a long Gio shot). 3. Usi

The forum signature is one of the methods of constructing the outer chain which is used by our optimization personnel. The reason why it can be so favored is mainly because of its low construction threshold and quick results, many optimization personnel in contact with the optimization of the initial start of the chain, and the construction of the outside chain from the forum signature began. Some optimizer

1. The meaning of the signatureIn order to guarantee the legal ID of each application developer, to prevent some of the open vendors from possibly confusing the installed program by using the same package name, we need to uniquely sign our released APK file to ensure consistency for each release we publish ( such as Automatic Updates will not be installed because of inconsistent versions).2. Procedure for signingA. Creating a keyB. Sign the APK using the key generated in step a3. Specific operat

Many predecessors in the garden are posting their ownArticleWhen I was thinking about it, there was a copyright statement at the end of the article. I felt very exquisite and wanted to do something like my predecessors, today, I made a copy of their signature. There is nothing special about it, as shown below: This blog looks very novel. There are two methods: Set through the blog signature. Al

Methods, instance constructors, indexers, and operators are characterized by their signatures: A Method signature consists of the method name and the type and type (value, reference, or output) of each of its parameters (in the order from left to right. Note that the method signature does not contain either the return type or the Params modifier (which can be used for rightmost parameters ). The instanc

Bob has a public and private key. Bob's public key is public and can be obtained by anyone. But only Bob has his own private key. Both the public key and the private key can be used to encrypt the information separately, and the encrypted information can be decrypted with the other key accordingly. For example, when Susan encrypts information with Bob's public key, she sends it to Bob. Bob gets the message, decrypts it with his private key, and obtains Susan's information. Other people, even i

CentOS Kernel Compilation and its signature mechanismThe signing mechanism introduced by Linux kernel 3.7 greatly facilitates the security authentication of kernel modules, and also provides the technical means of IP protection for operating system manufacturers. However, there are pros and cons to everything. For engineers who have just contacted a kernel with a signature mechanism, a process that understa
