I want to check the certificate used in the android APK file,so I used the follow command to print the info of certificate:
unzip -p name-app.apk META-INF/CERT.RSA | keytool -printcert
But,it said "filename not matched: META-INF/CERT.RSA". Hence,I check the file list in the APK file using the command as follow:
unzip -l name-app.apk| grep META-INF
It just showed three files in the folder 'META-INF':
- META-INF/MANIFEST.MF
- META-INF/WHATSAPP.SF
- META-INF/WHATSAPP.DSA or FILEEXPE.RSA
I cannot find out where the shoe pinches though i tried my best to search it online. So,my question are as follows: 1) if WHATSAPP.DSA is a replace of CERT.RSA 2) what does FILEEXPE.RSA describe?
Can someone shed light on this problem for me? Thanks in advance!
