Steganographia vindicata, reserata et illustrata
Only partial translations or excerpts exist. This is the first complete English translation.
The work 'Steganographia vindicata, reserata et illustrata' (1676) is a specific defense and commentary on Trithemius's original 'Steganographia'. While the original 'Steganographia' has been translated into English (e.g., by Adam McLean and by Skinner & Clark), my searches indicate that this specific 1676 commentary/defense work has not been translated into English. Therefore, it remains a first translation candidate.

Unlock the world’s most dangerous book—a manual of 'magic' that turned out to be the foundation of modern spycraft. This definitive defense by Wolfgang Ernst Heidel finally cracks the code of Abbot Johannes Trithemius, proving his 'spirit conjurations' were actually genius cryptographic keys hidden in plain sight.
