Broken github.io links in README and documentation.
Seahash's doccomments link http://ticki.github.io/, which is "404 There isn't a GitHub Pages site here.". There is even a failed picture embedding: [A diagram.](http://ticki.github.io/img/seahash_construction_diagram.svg).
It should be updated to point to correct blog article location or archive.org link like this.
Additionally, it sometimes uses non-secure links like http:// instead of https://.
