comment Encoding numbers that can be decoded mentally?
This is commonly called a Grocer's Code, and is used for this exact purpose. The US Army used the same code for map coordinates, with the key of BLACK HORSE.

comment Why to try get key out of white box crypto? How can one protect WBC itself?
@nightcracker, WBC includes the key, by definition. If you withhold the key, it's ordinary secret key encryption.

comment Are NIST's changes to Keccak/SHA-3 problematic?
80 bits is at the ragged edge of protection. You would be safe against most entities for a few more years, but probably not the NSA. Even so, any attacker would find it incredibly expensive to break, requiring a lot of dedicated hardware and consuming a lot of electricity. I wouldn't build a new system with anything less than 112 bits.
