Encryption

Encryption is great practice with coding PLUS your grand kids might get a kick out of sending secret messages to each other.

This is not encryption but is interesting because creates ever expanding line preserving and repeating the last line!


t = "0"
for
r = 1 to 5
s = t : t = ""
for i = 1 to len(s)
c = mid(s, i, 1)
if c = "0" then t = t + "010" else t = t + "110" '<<< build different patterns with variations here
next
print t:?
next
pause


Now for simple encryption just add a whole table of:
if
c = "A" then t = t + "F"
if
c = "B" then t = t + "Z"
....
until
through alphabet can add lower case letters, digits, punctuation even space!

And a decoder would do just the opposite
if
c = "F" then t = t + "A"
if
c = "Z" then t = t + "B"
...


When I was younger I used to solve Cryptograms with some ease. I still enjoy them but, because of lack of practice and decrepitude, they're not so easy anymore. Nonetheless, I still find encryption fascinating, and admire those that can create the algos to make it work.

Thank you for the 'flashback'.
