AFAIK, usually removed - they make it too easy to guess words. :-)
My guess is that some magical ciphers may rely on the shapes of their
letters for their power (rather than their unreadability), so there might
be examples of ciphers where spaces were retained.
I also don't know if there is a date before which people didn't think to
remove spaces at all.

I don't recall any of the sources I've read on early cryptography
specifically mentioning the reversible coding of blanks in ciphertext, but
it's certainly possible. For example, in the past I've suggested a "space
transposition cipher": this would work by removing real spaces and
inserting fake spaces at plausible-looking syllable ends (say).
ie: fo rex amp leint hepas ti vesug ge ste dasp acet ran spo siti oncip her. :-)
This is, however, purely conjecture on my part (and is only "mostly
reversible"). :-o

Again, it's certainly possible, but I don't know of any recorded examples
in early cryptography. My instinct would be that this would have been
conceptually unlikely in Europe before the advent of printing (because it
requires seeing space as a serialised printed character), and only vaguely
plausible after that (because thinking in ASCII is a modern peculiarity). :-o

hi all :-)

~WRONG MIRROR~? the above is a REVERSE MIRROR (with spacings)(as in a
reflecting looking glass)
*see the FOLD*
But you're closing in on IT !!! :-) :-)
D*Rn, this is _harder_ to explain, then shown by ES (ha.ha), but, try
this:
AND, *YES* I know I'm just 1 of 12 (so, 11 more helps needed here)
AND, *YES* I know I'm suggesting 1/2 entropy to both ALPHA & Numeric
entries (per # (TTT) area of a folded key), but THIS FOLDING/ 8*
produces the VMS's _LoW entropy_ (using most any Language)
BOTH SIDES *FIT*: But not "(reflective)Mirror", closer to Jeffs
reversing of my folded key... that change my left to right (top to
bottom) to HIS (up & down / reversed.mirror)
But, (per ES) this has NO recorded examples in early/current
cryptography!
expert? NO, Touched by ES (once) * Y E S *, &/or since? = NO
I think (dumb steve dumb?) that THAT was the reasaon for the ES Visit
10.6.2000(MST:22:45)10:45PM. The TIME IS NOW for this NEW deCODING.
I can remember THIS DATE?... when are my family dates/b.dates? I
haven't
a clue (1/2 time)... - while this proves nothing, I would just like to
suggest
that NO-ONE has SEEN/RECORDED this coding before -- (SoRrY, I knew
THAT from
day
1, & that is the only reason I bothered to tell you all about it)...
IT IS W A Y COOL, and good for ALL (esp. women), but G O O D for
ALL!
Seemed the ~WORLD SHOULD KNOW NOW~ :-)
best to you & yours

*8 (note) the actual "folding of your KEY paper/vellum?" produces the
TTT (or Tic.Tac.Board effect - 9 <NINE>squares TOTAL), since ES said
"THE CENTER IS
YOURS", I assume(?) the "languages (alpha/num.1/2'd) possibles" ARE
(8x4)x2= 64 x2= 128 | TOTAL ON THE LOW SIDE of the Language Inserted.
Grabbing it "ALL" (per ES /OURS?) + CENTER TTT = (9*4)x2= 72 x2 =144
| TOTAL ON THE _HIGH SIDE_ of the/any Language Inserted.
but the
gallows fall
apart _above_ this #9 number :-(
The 'double exposure' or a number or position would to me explain why
the computer people find it facinating. (just looking at it overall)!
