You should recognize NXANKX right away.
The I could see that all the letters in PFX (which is a common word in the CG and probably a verb) are in JDPFHXF. So it wasn’t too hard to finally figure out JDPFHXF.
Then the rest fell into place. Except I don’t know what the 1st letter in author’s last name is, although I could make a good guess.
