Android view signature information

1.pk8 and x509.pem generate jks

https://blog.csdn.net/laipigui905/article/details/112347159

2. View jks sha256

• keytool -list -v -keystore xxx.jks
• enter key
  

3. View apk sha256

• unzip the apk
• keytool -printcert -file xxx\META-INF\CERT.RSA
  

4. View the signature of an apk through python

# -*- coding: utf-8 -*-
#coding:utf-8
