问题描述

我已经与默认的debug.keystore键签署了我的APK.但是不幸的是，我的系统被破坏了，现在我需要从已经签名的APK中获取密钥存储.

用新APK替换旧APK.

我有md5，带有指纹.

任何建议都将不胜感激.谢谢您.

首先，解压缩APK并提取文件/meta-inf/android_.rsa(此文件也可以是cert.rsa，但只有一个.rsa文件).

然后发出此命令:

keytool -printcert -file ANDROID_.RSA

您将获得这样的证书指纹:

 MD5:  B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB
 SHA1: 16:59:E7:E3:0C:AA:7A:0D:F2:0D:05:20:12:A8:85:0B:32:C5:4F:68
 Signature algorithm name: SHA1withRSA

然后再次使用键盘打印签名密钥库的所有别名:

keytool -list -keystore my-signing-key.keystore

您将获得一个别名及其证书指纹列表:

android_key，2010年1月23日，私人按键，证书指纹(MD5):B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:AE:8C:17:DB 瞧！现在，我们可以确定APK已与此密钥库签名，并且使用别名为" Android_key".

keytool是Java的一部分，因此请确保您的路径中有Java安装DIR.

I have already signed my apk with default debug.keystore key.But unfortunately my system destroyed,Now I need to get the key store from the already signed apk.

to replace with old apk with new apk.

I have MD5,SHA fingerprints with.But i could make them as keystore to sign the apk.

Any suggestions would be appreciated.Thank you in advance.

First, unzip the APK and extract the file /META-INF/ANDROID_.RSA (this file may also be CERT.RSA, but there should only be one .RSA file).

Then issue this command:

keytool -printcert -file ANDROID_.RSA

You will get certificate fingerprints like this:

 MD5:  B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB
 SHA1: 16:59:E7:E3:0C:AA:7A:0D:F2:0D:05:20:12:A8:85:0B:32:C5:4F:68
 Signature algorithm name: SHA1withRSA

Then use the keytool again to print out all the aliases of your signing keystore:

keytool -list -keystore my-signing-key.keystore

You will get a list of aliases and their certificate fingerprint:

android_key, Jan 23, 2010, PrivateKeyEntry, Certificate fingerprint (MD5): B3:4F:BE:07:AA:78:24:DC:CA:92:36:FF:AE:8C:17:DB Voila! we can now determined the apk has been signed with this keystore, and with the alias 'android_key'.

Keytool is part of Java, so make sure your PATH has Java installation dir in it.
