Blu-Ray certificates and JAR signing

[radius]

Hi,

I've been wondering for some time how to edit and re-sign JAR files from a blu-ray but could not really find real tutorials,
I'd like to edit JAR stuff like xmls or images then rebuild the JAR and resign it,
Actually I've been testing with scenarist BD-J and app.discroot.crt creation / signing but the signed JARs I get are not usuable,
btw I didn't use any bu.discroot.crt signing at all as I just have no idea how to use them,

Could someone point me to any tutorial / procedure I could use to learn about all this signing stuff ?

Thanks

This is not the case for every JAR, some are signed and do not work after tampering with them. Take the new Sony BD-J protection on House on Haunted Hill (German) and Eclipse (Italian) for example.

Thanks,
I already had this idea but in my particular case JARs from Inception get sort of corrupted after they are modified by anydvdhd and some stuff won't work anymore :/,
I'll try to submit this to their support ^^

With new protections, dvdfab is better these days. You can try with it the same thing. This is the only way to resign them properly, because they have some passwords and a powerful encryption key.

Thanks, I'll give it a look :)

Hello everyone.

Scenarist Safeguard 5.7.1 (Complete Scenarist BD v6.X.X) includes storage 'Project.keystore' but I do not know the password.
Does anyone know the password?

[rik1138]

It doesn't include one, the keystore contains the encryption keys for your JARs. _YOU_ create this (or your client if you are working with a studio).

Can you actually browse to a project.keystore _file_? The program starts up with a default one listed, but if you start typing a password, it immediately says 'database file does not exist'. Scenarist can't give you a keystore file since they don't have your signing keys. Just click 'create new file' and you can then create or import your keys. They make the keystore password protected to prevent unauthorized signing...

If you need help with using Safeguard, I believe Scenarist has tutorials on using it. It's not always intuitive... :)

Good! I will create my storage.

Thanks rik.
