This is just a simple skip if the hash is known as "empty". For example:
These hashes were uncrackable for oclHashcat-lite in the past. Nearly all hash-types are support. With one restriction. If its a salted hash-type, this works only for these hash-types that allow empty salts. There are also plans to add these, but this requires to add some 3rd party library. Polarssl would be a good choice since its well written and the license is compatible...
