Check out Google's implementation of URL Canonicalizand hashing, it is interesting. (just a thought)

`Canonicalize("http://host/%25%32%35") = "http://host/%25";
Canonicalize("http://host/%25%32%35%25%32%35") = "http://host/%25%25";
Canonicalize("http://host/%2525252525252525") = "http://host/%25";
Canonicalize("http://host/asdf%25%32%35asd") = "http://host/asdf%25asd";
Canonicalize("http://host/%%%25%32%35asd%%") = "http://host/%25%25%25asd%25%25";
Canonicalize("http://www.google.com/") = "http://www.google.com/";

I came across the documentation above while trying to understand how sha256 hashing works. They could do with improvements but i also think ZeroNet could benifit from some of the working structures used for inspiration.

No ZeroNet files, tests, or entry points are identified. Start by reviewing the linked Google Safe Browsing URL hashing documentation and determine whether a concrete ZeroNet change is intended; the issue does not define a measurable completion condition.
