project, we are very happy to find the source code of signapk. jar! Path:/build/tools/signapk/SignApk. java.
Comparing an unsigned APK and a signed APK, we will find that there is a folder named META-INF in the signed APK package. There are three files named MANIFEST. MF, CERT. SF, and CERT. RSA. Signapk. jar generates these files (other files have not changed. So we can easily remove the original signatur
APK File Analysis-AndroidAfter Android is packaged, an APK file is generated.The APK file is actually a zip file.For example, if you change the suffix of filecycler.apk to zip, it becomes filecycler.zip.The ultimate file also has an Excel file, such as fansunion.xlsx, which is suffixed with fansunion.zip. After decompression:_ RelsDocPropsXl[Content_Types]. xmlIf you are interested, try it by yourself ~After decompression:META-INF-- CERT. RSA--
Configuration method:
1. A Running System in the kernel (centos 6.5)
2. Install squid on the server
3. Generate a certificate on the server and use an encrypted proxy.
4. Install Stunnel in the wall. It can be a Windows system or a Linux system (this case is Linux)
1. Server Configuration
1. Install squid
#yuminstall-ysquid
2. Generate a certificate

Then write a read method in the CERT class to read the certificate. Note: The pfx file may contain several certificates.

Tomcat supports the JKS format certificate, and the PFX format certificate is supported starting from TOMCAT7, with either of the two certificate formats selected. File Description: 1. Certificate file 21397867314xxxx.pem, which contains two pieces of content, do not delete any part of the content. 2. If the CSR is created by the certificate system, it also contains: Certificate private key File 21397867314xxxx.key, PFX format certificate file 21397867314xxxx.pfx, PFX format certificate password

Open-source virtualization format ovf (different from lower-case ovf) files are an open-source file specification, it describes an open-source, secure, effective, and scalable portable virtual package and software distribution format. It generally consists of several parts, ovf files, MF files, Cert files, vmdk files, and ISO files.
