I ran into this issue too. Could you add this to the docs, or perhaps provide more informative error?

Yeah, its mentioned in the doc page, but it didn't sink in.

You also need to add the java crypto extensions with 'unlimited strength'
keys. Simple download from Oracle, but separate from standard jdk. Copy
two jars across to your jdk install and done.

Interesting is that I needed these same keys for the "Keystore Explorer"
tool too.

Good luck, should be cake.

@lid The unlimited unlimited strength policy requirement is mentioned in the linked blog post, but I guess not many people read that far. The message comes from the Oracle's JCE provider. I guess all of this could be avoided by simply adding BouncyCastle as the default provider, but for now I've just added the JCE requirements to the README.
