安卓密钥库已损坏
在一段时间没有更新Play商店中的应用程序后，我试图用我的密钥库对我的一个APK进行签名，结果发现密钥库和别名密码不再有效。我能够使用此要点重置密钥库密码：并且现在工作正常。对于两个不同应用程序的两个不同的密钥库，会发生这种情况。gist.github.com/zach-klippenstein/4631307
运行结果是：keytool -list -keystore mykeystore
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
myalias, Dec 23, 2014, PrivateKeyEntry,
Certificate fingerprint (SHA1): 85:8F:69......
我100%确定别名密码与密钥库密码相同，但它似乎不起作用。我尝试过在Android Studio中签署APK，但响应始终是：.jarsigner -keystore mykeystore -storepass mykeystorepassword app-debug.apk myaliasjarsigner: unable to recover key from keystore
我尝试将别名移动到新的密钥库文件，然后要求我输入新密钥库的新密码和旧密钥库的密码（两者都有效），只有在输入别名密码后，我才得到一个例外：keytool -importkeystore -srckeystore mykeystore -destkeystore newkeystore -srcalias myalias
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
经过一些谷歌搜索，我发现对于某些人来说，密钥库在更新到另一个JDK版本或Android Studio版本后停止工作，所以我想知道我是否也是这种情况。密钥库创建于2014年，所以我当时可能在JDK7上（我现在8岁）。这也是可疑的两个密钥库神秘地停止工作。
这可以以某种方式修复吗？
编辑：
我尝试了Jan的解决方案，并得到了以下结果：
keytool -importkeystore -srckeystore mykeystore -destkeystore newkeystore -deststoretype pkcs12给了我同样的例外：.keytool error: java.security.UnrecoverableKeyException: Cannot recover key
运行此命令后：我收到此错误：keytool -importkeystore -srckeystore newkeystore -srcstoretype pkcs12 -destkeystore finalkeystore -deststoretype jkskeytool error: java.io.IOException: DerInputStream.getLength(): lengthTag=109, too big.
第二次编辑：
我还尝试用JDK7在PC上签署apk，没有运气。
第三次编辑：
我尝试使用密钥库资源管理器，它打开密钥库文件很好，并显示一个条目（未过期）。当我尝试打开私钥时，我得到同样的异常。堆栈跟踪：
