java.io.IOException: Invalid Keystore format

Question

Does anyone know how to solve this? I tried many things, but none of them worked.

And when I click more details I get this:

Answer 1

Maybe maven encoding you KeyStore, you can set filtering=false to fix to problem.

<build>
    ...
    <resources>
        <resource>
            ...
            <!-- set filtering=false to fix -->
            <filtering>false</filtering>
            ...
        </resource>
    </resources>
</build>

Answer 2

Your keystore is broken, and you will have to restore or regenerate it.

Answer 3

You may corrupt the file during copy/transfer.

Are you using maven? If you are copying keystore file with "filter=true", you may corrupt the file.

Please check the file size.

Answer 4

(Re)installing the latest JDK (e.g. Oracle's) fixed it for me.

Prior to installing the latest JDK, when I executed the following command in Terminal.app:

keytool -list -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -v

It resulted in:

keytool error: java.io.IOException: Invalid keystore format
java.io.IOException: Invalid keystore format
    at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:650)
    at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55)
    at java.security.KeyStore.load(KeyStore.java:1445)
    at sun.security.tools.keytool.Main.doCommands(Main.java:792)
    at sun.security.tools.keytool.Main.run(Main.java:340)
    at sun.security.tools.keytool.Main.main(Main.java:333)

But, after installing the latest Oracle JDK and restarting Terminal, executing the following command:

keytool -list -keystore $(/usr/libexec/java_home)/jre/lib/security/cacerts -v

Results in:

Enter keystore password:  

Which indicates that the keytool on path can access the keystore.

Answer 5

I think the keystore file you want to use has a different or unsupported format in respect to your Java version. Could you post some more info of your task?

In general, to solve this issue you might need to recreate the whole keystore (using some other JDK version for example). In export-import the keys between the old and the new one - if you manage to open the old one somewhere else.

If it is simply an unsupported version, try the BouncyCastle crypto provider for example (although I'm not sure If it adds support to Java for more keystore types?).

Edit: I looked at the feature spec of BC.

Answer 6

I ran into the problem with openJDK on ubuntu, had to install Oracle JDK to get it working.

You can follow this guide on google sites to do that.
