Re: [freenet-devl] 0.4 Standard for Keys, Storables, and Document structure

[Scott Gregory Miller]

If we use chunks instead of control bytes, then we definitely want to
still keep it as compact as possible, and that means binary.  Don't switch
to FNP chunking.

Thats difficult.  We want documents to collide, so they all must produce
the same padding.  And if they do, then an attacker knows what the padding
will look like.  Almost...

What you can do is just hash the last n real bytes, drop that as padding,
then hash that, drop as padding, etc until you're done.
