The Naibbe cipher

[magnesium]

I was actually thinking of an IVTT command on the command line that does everything in one go. Maybe @ReneZ can help here. I know the following command that extracts the entire text:

ivtt -x7 ZL3a-n.txt outputfile.txt

I just need to know the parameter to extract Currier B.

I believe you just need to add "+LB," like in the example on page 6 here: You are not allowed to view links. Register or Login to view.
