怎么查看apk的签名 keystore

Answer 1

1、查看 keystore
$ keytool -list -v -keystore debug.keystore
$ keytool -list -v -keystore debug.keystore
Enter keystore password:

***************** WARNING WARNING WARNING *****************
* The integrity of the information stored in your keystore *
* has NOT been verified! In order to verify its integrity, *
* you must provide your keystore password. *
***************** WARNING WARNING WARNING *****************

Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

Alias name: androiddebugkey

2、查看三方应用或是系统应用签名
打开待查看的apk，将其中META-INF文件夹解压出来，得到其中的CERT.RSA文件

$ keytool -printcert -file META-INF/CERT.RSA
打开待查看的apk，将其中META-INF文件夹解压出来，得到其中的CERT.RSA文件
$ keytool -printcert -file META-INF/CERT.RSA

Signature algorithm name: SHA1withRSA

Version: 3

3、给空白包签名 （注意 alias 值）
jarsigner -verbose -keystore [keystorePath] -signedjar [apkOut] [apkIn] [alias]

jarsigner命令格式：-verbose输出详细信息 -keystore密钥库位置 -signedjar要生成的文件 要签名的文件 密钥库文件
keystorePath参数代表keyStore的绝对路径，如D:\keystore
apkOut参数代表签名后的apk路径，如D:\signed.apk
apkin参数代表在腾讯应用中心下载的未签名apk，默认名称为tap_unsign.apk
alias参数代表签名用的alias名称（创建keyStore时所填写），如timdong
$ jarsigner -verbose -keystore debug.keystore -signedjar test2.apk tap_unsign1.apk timdong

Enter Passphrase for keystore:

adding: META-INF/MANIFEST.MF

adding: META-INF/ANDROIDD.SF

adding: META-INF/ANDROIDD.RSA

signing: res/drawable/ic_launcher.png

signing: res/layout/main.xml

signing: AndroidManifest.xml

signing: resources.arsc

signing: classes.dex

Answer 2

没有签名密码导出没有用
