The VMS as a possible chain encryption ( Mod 23 ).

[bi3mw]

As an experiment could you try encoding some very simple maybe even repetitive English (or Latin) text using this method? I suppose it will become something like qtopihfdsjnvmglcxwtaksdbnkfhdyf - pure randomness and few obvious patterns.

I am not sure if I have understood this correctly, but here is a Latin text excerpt and below it the corresponding encryption:

Capitulum primum De regulis sumptis ex parte elementorum nostro corpori occurrentium ab extra
supra Non debet esse terra cuius habitatio eligitur lutosa nec scenosa nec fetens nec limosa nec super quam virtus metalli sit superans nec sulphurea nec aluminosa nec in qua sint vel fuerint mortuorum cadauera nec malis herbis aut arboribus fecundata sed bonis puta vineis salicibus herbore pini similibus amicabilibus nostris corporibus Sunt enim que dam plante que multum inimicantur nobis sicut experientia docet de arbore nucum et de aliis multis arboribus vt persico populo arbore sambuco et ficu Terre igitur fecundate his arboribus non sunt bone habitationis supra Et similiter intelligatur de herbis Sunt enim quedam venenose herbe quibus terra fecundata non est conueniens habitationi
vt est elleborus esula solatrum mortale et similia Et per oppositum fecundata bonis herbis supra et odoriferis est conueniens habitationi nostre Amplius non debet esse terra cauernosa inter supra montes inclusa nec nimis montuosa Et terra melioris habitationis debet esse discooperta ab oriente a septentrione Nam illi duo venti sunt magis purificantes aerem illius habitationis Vnde et in mansionibus bonum est fenestras esse septentrionales et orientales non meridionales nec occidentales Et hoc verum est regulariter sed interdum contingit per accidens ventum septentrionalem esse deteriorem meridionali Possible enim est quod ventus transeat per aliquam partem septentrionis niuibus occupatam vel adustam vel minerosam vel lutosam vel corruptam aliquo modorum corruptionis supradictorum et sic ventus septentrionalis erit impurior et minis eligibilis Et similiter intelligitur de parte orientis Bonum est igitur interdum per accidens fenestras habitabilis terre seu spiracula esse a parte meridiei vel occidentis quamuis supra regulariter contrarium sit eligibile Vicinitas quoque aquarum dulcium currentium multarum et mundarum que in hyeme cito infrigidantur et in estate cito calefiunt Et similiter pratorum viridium non vmbratorum multis arboribus est res conueniens habitationi et adiutorium prebens

There are definitely word repetitions (as I said, the mapping is rudimentary). It is striking that the last letter in the preceding word must also be identical.

   

The entropy actually increases a bit.
