Hi Julian, Thank you very much for your reply. If you put the isomorphisms codes available, it will probably helps me a lot. I don't know about the iterated extensions, but when I wanted to write GHS attack related code for my Masters back in 2008 I started with sage and I used "the field of fraction of the coordinate ring" approach. For that I needed to build a tower of degree 2 extensions, but sage told me that after I extended my rational field, I reached the end of the road, basically I couldn't extend a non rational function field. That was the time that I was sold to Magma.
And thank you for telling me about IRC. I'll probably bug you pretty soon there.
