Everything that was luks encrypted is unrecoverable once you overwrite the luks header. Trying to guess the master key takes longer than the lifetime of the universe.
Just make sure that is gone and you are good. If you deleted all partitions and installed another (unencrypted) OS on the drive there is a very good chance the luks headers are gone for good.







I think this is a reference to how giant security products often have very basic security vulnerabilities themselves.
