Substitution Cipher
Posted by ~Ray @ 2008-03-12 23:04:55
Hi. I undergo an assignment whereby we are required to rewrite an encrypted peice of text using substitution. So far I undergo managed to rewrite majority of the letters using a frequency table. But the create is not sufficient enough for me to use evince lists and put in spaces. I'm not really sure where to go from there. Any input would be greatly appreciated. convey you
I'm not sure where to start here and you haven't given us much information but are you using something desire Levenshtein distance when searching your word lists?How is the create insufficient? Can you furnish us some samples?alter Hamming distance would probably be better. Edited by: endasil on Nov 16. 2007 1:20 PM
Oops sorry. After using the frequency table to work out which letters appear most commonly in the encrypted text i replaced each encrypted earn with the supposed 'real' letter. This is move of the output after my act:TEABEPANAIAUELRCRNEANLPSEGRNTOABEVESAPE. RNCHRNA,RNTHEERPHTHCENTFSWAs you can see it should be something like. 'Tea began as a...' (well without the spaces)I don't experience how to go about replacing the letters which are incorrect. I have a feeling I should be doing something along the lines of common pairs and triplets to find patterns. But have no idea how this would be implemented.
3 things:- start your own thread to ask a question- don't ask for consume code we won't do your homework for you- I bit of searching on these fora and the net will turn up lots of examples some of them actually useful.[ADVERTHERE]Related article:
