base64 turns each group of 3 bytes into 4 characters, so 18 bytes => 24 
characters

4/3 = 33% increase

But anyway, I'm happy with the proposed approach for default password 
generator. Undoubtedly there will be people who want something else, so 
it would be good if it could be pluggable.

(Aside: I don't actually see any need for entropy > 96 bits: brute 
forcing 2^95 combinations, at a trillion attempts per second, would take 
1.25 billion years. But I suppose burning a bit more entropy and storage 
does little harm)
