Re: A Little Decoding Challenge

Re: A Little Decoding Challenge Yes, that should work fine. The problem is getting ascii braille in the first place. For me that meant a note taker, and I've yet to find any free software that can do it on Windows.If folks are really interested I can put a bit more work into the encoder

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge The basic laymen's difference between encoding and encryption is that encoding is more of a substitution where encryption is a deliberate obfuscation of the plane text.for example, an encoding might be I substitute all of the letters on the forum here

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge Rocky, it was because when I had tried those techniques the encoded messages had a mistake in them.  John later fixed it, but after the correction I never had time to go back and redo my tests.   It was a fun puzzle nonetheless. URL: http

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge @Rocky:The encoding is two-way, and lossless. The examples can be shifted either way as many times as you want and will end up with the same results. URL: http://forum.audiogames.net/viewtopic.php?pid=340276#p340276

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge I'm baffled.  We hear it's not encryption, ruling out frequency analysis, but a computer can run an algorithm to code and to presumably decode.  Unless the decoding is not possible, being a sort of one way coding, once again ruling out any mapping.  I also

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge Hi folks,I just went to put together a third sample of text, and discovered to my horror that my encoder had a small glitch that was causing it to omit a character. Since this character never appeared in the section I'd done by hand, it looked like

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge Ah, I missed several single-char words, including a lowercase 1. That confuses things a bit... And there is a bu in the middle of nowhere, and I think that's the only bu that doesn't start a -t sentence. Hmm. URL: http://forum.audiogames.net/viewtopic.php

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge The idea of t as a line break or punctuation made me realize that both samples start with b, so I went back to check, and it also seems that every t-delineated chunk also starts with not just b, but bu. I think ti is more likely punctuation than a line break

Re: A Little Decoding Challenge I've finally changed my direction entirely.  I was about to drift off to nap-land on the sofa when an idea popped into my head.  I got up and checked the frequency graph from earlier, and sure enough my hunch was correct and I was looking at it wrong.  When

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge @Aprone:You're getting closer, that's for sure. I did say this isn't a shift. I didn't say there wasn't a character-to-character mapping (not that there is or isn't, but I wanted to clarify my meaning).I find the "t is a line break" theory to

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge There's not much I can say without giving way too much away. Again though, don't think encryption. Seriously. Don't think encryption, don't think hashing. The first sentence takes less than 10 minutes to encode by hand without a calculator of any sort (I

Re: A Little Decoding Challenge

Re: A Little Decoding Challenge Continuing from Aprone's observations...So, if we run with the idea that a is a word delimiter, then there are 3 single-letter words in the first sample. That's kinda weird if we're talking standard English, but there is an English writing system with loads
