How to provide an anonymous copy of work online? It may seem odd, but I need to put an anonymous part of my work (an algorithm) online.

Well, it should be available online as I want to refer to it in a single-blind submission (but not as the contributions), and it should be anonymous as I want to introduce it (as the contribution) in another conference submission (with double-blind review). Since the submission deadlines are close to each other I want to handle it like this.

Is there a way to put it online with anonymous author names (arXiv does not allow it) so it could also be searchable via google?

I will remove it or update it with full names after the paper review process is finished.
I added the work to vixra.org which is similar to arxiv but with fewer boundaries. Maybe it does not have the reputation of arxiv, but i used it for anonymous uploading of my work.
