Now I'm no genius, but basics of cryptography is to try the simplist methods first. For anyone who's interested, here you go. Use UNDO as the input_string to undo something, and ESC to quit: Turn Write_To_File = true to write your decrypt to file. NOTE: This does not support switching more than one character in one move. I'm pretty sure you'd want to use MID for that and I don't use MID. Const false = 0, true = not false
'Dim your Variables Here: dim counter = 0
dim write_to_file as integer 'If this is true, then it will write the text to a file: write_to_file = true
dim a as string
dim b(0 to 25) as string
'Put the Crytext into a string: A = "GY QSS ZIT YGKXD DTDWTKL ITKT, DQFN QKT ESTCTK TFGXUI ZG YOUXKT ZIOL GXZ. QUQDTDFXL OL HQKZOEXSQKSN UGGR QZ ZIOL LGKZ GY ZIOFU, QFR LG O'D WTZZOFU ZIQZ IT VOSS VOF ZIOL EGDHG. UGGR SXEA ZG QSS, QFR OY NGX QKT ZIOL YQK QSGFU, EGFUKQZL, NGX IQCT OZ!" B(0) = A
dim a_save(0 to len(a)) as integer
'The Variables for the Input and Replace: Dim Input_String as string Dim Replace_String as String
do 'Clear the Screen and Print the text: cls Print A 'Input, the string you want to replace: Input "Which letter will you replace? ", Input_String 'If the string is UNDO then undo: if ucase$(input_string) = "UNDO" then 'If it's legal to do so, go back one step: if counter > 0 then counter -= 1 end if A = B(counter) 'If the String isn't undo, then add to the changes made: else If ucase$(Input_String) = "ESC" then If write_to_file = true then open "Cryptext.txt" for output as #1 Print #1, A Close #1 end if end end if counter += 1 'What do you want to replace your string with?

", Replace_String 'Replace all characters of Input_string with your Replace_String for do_text = 0 to len(a) - 1 'If A, character do_text is equivalent to Input_String, replace with ReplaceString: if a[do_text] = asc(input_string) then if a_save(do_text) = false then a[do_text] = asc(Replace_string) a_save(do_text) = true end if end if next end if 'Make the undo_string = A: B(counter) = A

of all the forum members here, many are clever enough to figure this out. agamemnus is particularly good at this sort of thing, and so i'm betting that he will win this compo. good luck to all, and it you are this far along, congrats, you have it!  .... Few minutes in FBIde changing the letters around as they fitted.. :mrgreen:

I was wondering what 3 letter word has two letters that are the same...That would make sense. How on earth could I have missed the world, "All"? That's normally the simplist one to figure out... ^_^;; EDIT: Updated program to know whether you have switched a letter already or not. No more problems with switching H to I, then I to whatever...

How on earth could I have missed the world, "All"? I was thinking a-s-s for a bit, but then I saw I hadn't swapped the S's yet... :shifty:

No more problems with switching H to I, then I to whatever...  Thnx  This was a fun challenge. Make another crypto plz

@Z!re: you sure there aren't undisplayed characters in there? There would be if you copied it directly from some sort of bitwise encryption. Anywho, good job all! Here's the code that generated it - notice how the character correspond. :wink: dim as string kb,ol,phrase,temp,c_phrase dim as integer offset kb="QWERTYUIOPASDFGHJKLZXCVBNM" ol="ABCDEFGHIJKLMNOPQRSTUVWXYZ" phrase="OF ALL THE FORUM MEMBERS HERE, MANY ARE CLEVER ENOUGH TO FIGURE THIS OUT. " + _ "AGAMEMNUS IS PARTICULARLY GOOD AT THIS SORT OF THING, AND SO I'M BETTING " + _ "THAT HE WILL WIN THIS COMPO. GOOD LUCK TO ALL, AND IF YOU ARE THIS FAR ALONG, " + _ "CONGRATS, YOU HAVE IT!" apos=asc("A") zpos=asc("Z") for i=1 to len(phrase) temp=mid$(phrase,i,1) if asc(temp)>=apos and asc(temp)<=zpos then offset=asc(temp)-apos+1 c_phrase+=mid$(kb,offset,1) else c_phrase+=temp end if next print phrase print c_phrase sleep

Interesting. I made something that compares English letter frequencies and it has about half the letters correct. It's possible to make it more correct by adding in letter frequencies for common words, etc. I don't want to post it yet though, 'cause half correct letters still look like mumbo jumbo. Maybe when/if I put in the 2-letter word frequencies...

I found a cryptogram solver which generates a random key, compares the frequencies to plaintext, and then modifies the random key until it gets the best match. Then it generates another random key, and so on, until the plaintext is mostly revealed, at which time you halt the program and copy the answer. Basically a genetic algorithm.
