1 查看apk的sha1值

有时，希望查看到对应签名了的apk文件的sha1值。使用下面脚本，脚本文件为showInfo.sh ：

#!/bin/bash  
get_signature() {  
    path=`jar tf "$1" | grep RSA` 
    jar xf $1 $path 
    keytool -printcert -file $path 
    rm -r $path 
}  
  
mypath=`pwd`  
filepath=""  
if [ -d .temp_for_certificate ]  
then  
    echo ".temp_for_certificate is exist,remove it first!"  
    exit  
fi  
  
mkdir .temp_for_certificate  
cd .temp_for_certificate  
count=0  
while [ -n "$1" ]    
do    
    if [ `expr substr "$1" 1 1` = "/" ] #绝对路径  
    then  
        filepath="$1"  
    else #相对路径  
        filepath="$mypath/$1"  
    fi  
    if [ -d $filepath ]  
    then  
        all_apk=`find $filepath -name "*.apk"`  
        for apk_path in $all_apk  
        do  
            count=$[$count+1]  
            echo "(#$count) "`basename "$apk_path"`":"  
            filepath=$apk_path  
            get_signature "$filepath"  
            echo "-----------------------------------------------------------"  
        done  
    else  
        count=$[$count+1]  
        echo "(#$count) "`basename "$1"`":"  
        get_signature "$filepath"  
        echo "-----------------------------------------------------------"  
    fi  
    shift  
done    
cd ..  
rm -r .temp_for_certificate  
echo "done!"

调用方式：

sh showInfo.sh <file-name apk>

e.g.

sh showInfo.sh eletricpower.apk

(#1) electricpower.apk:

]
]

2 显示apk信息

      jarsigner -verify -verbose -certs electricpower.apk
