一段时间未更新Play商店中的应用程序后，我尝试使用 keystore 对我的APK进行签名，结果发现 keystore 和别名密码不再起作用。我可以使用以下要点重设 keystore 密码:gist.github.com/zach-klippenstein/4631307，现在可以正常使用了。对于两个不同的应用程序，两个不同的 keystore 会发生这种情况。
运行keytool -list -keystore mykeystore导致:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
myalias, Dec 23, 2014, PrivateKeyEntry,
Certificate fingerprint (SHA1): 85:8F:69......
我100％确定别名密码与 keystore 密码相同，但是似乎不起作用。我尝试在Android Studio中使用
jarsigner -keystore mykeystore -storepass mykeystorepassword app-debug.apk myalias对APK进行签名，但响应始终是:jarsigner: unable to recover key from keystore。我尝试将别名移动到带有
keytool -importkeystore -srckeystore mykeystore -destkeystore newkeystore -srcalias myalias的新 keystore 文件中，然后要求我输入新 keystore 的新密码和旧 keystore 的密码(两者均有效)，只有输入别名密码后，我才会出现异常:Enter destination keystore password:
Re-enter new password:
Enter source keystore password:
Enter key password for <myalias>
keytool error: java.security.UnrecoverableKeyException: Cannot recover key
经过一番谷歌搜索后，我发现对于某些人来说， keystore 在更新到另一个JDK版本或Android Studio版本后就停止工作了，所以我想知道对于我来说是否也是这种情况。 keystore 创建于2014年，因此当时我可能使用的是JDK7(我现在是8岁)。这也是可疑的两个 keystore 神秘地停止工作。
可以以某种方式解决此问题吗？
编辑:
我尝试了Jan的解决方案，并得到以下结果:
keytool -importkeystore -srckeystore mykeystore -destkeystore newkeystore -deststoretype pkcs12给了我同样的异常(exception):keytool error: java.security.UnrecoverableKeyException: Cannot recover key。运行此命令:
keytool -importkeystore -srckeystore newkeystore -srcstoretype pkcs12 -destkeystore finalkeystore -deststoretype jks后，出现此错误:keytool error: java.io.IOException: DerInputStream.getLength(): lengthTag=109, too big.第二编辑:
我也尝试过使用JDK7在PC上签名apk，这不走运。
第三编辑:
我尝试使用KeyStore Explorer，它会很好地打开keystore文件并显示一个条目(未过期)。当我尝试打开私钥时，出现相同的异常。堆栈跟踪:

最佳答案
尝试
keytool -importkeystore -srckeystore old.keystore -destkeystore new.keystore -deststoretype pkcs12
和
keytool -importkeystore -srckeystore new.keystore -srcstoretype pkcs12 -destkeystore final.keystore -deststoretype jks
如this question中所建议。
