Zotero => bibtex with md5 identifiers

I was just hesitated to see annoying useful BibTeX ids like: "???_tonejito_???" so I found this page [1] that shows how to mess with the Zotero Firefox plugin, and I came out with the idea of using the md5 of the title as identifier (for me that is better than the other id).

The file in question was <FirefoxProfile>/zotero/translators/BibTeX.js the whole code is javascript so it's easy to modify and play with.

Looking around the web I also found this github:gist [2] to calculate an md5 sum from a given string, I pasted all the code at the end of the file and used the md5_hex function as follows to replace the element key.

I'm currently using the Zotero plugin [3] and the zotero bibtex auto-exporter plugin [4], I tested this using the preferences pane for the autoexporter and run a manual test. After a couple of tries the results were like this:



@misc{20c7358045528f33804340fb6510b8b9,
title = {tonejito {(Andres} Hernandez) · {GitHub}},

file = {Andres Hernandez (Tonejito) on Twitter:/Users/tonejito/Library/Application Support/Firefox/Profiles/profile.default/zotero/storage/CCCCCCCC/tonejito.html:text/html}
}



So I can use any of this hashes in a LaTeX document like this and the bibliography entries will be sorted and referenced correctly.
