I'm starting a new thread for this.

I now have working Python scripts for encrypting the fonts in ePubs, one for the Adobe method and one for the IDPF method.

Since the code is very similar, I'm pretty sure I have the code for the IDPF method done correctly.

My Adobe code produces ePubs that ADE will read, but which are obfusticated sufficiently that operating systems can't read them.

My IDPF code produces ePubs that look right, but that ADE will not read.

So at the moment it looks like going the Adobe route is best.

I still need to add a bit to my code a bit, (currently I have to add the encryption.xml file by hand), but it should be available by the end of next week.

Does anyone know of any ePub reader that will read IDPF obfusticated fonts? I'd like to test both

I'm also pondering whether it would be possible to include /both/ encryptions in some way. Anyone got any ideas?
