Cryptography with Pext By Kyro [9:33 AM, 5/5/2014] - - - - - - - - - - - - - - - What is Pext? Pext is a complicated method of encryption known to most cryptographers as the "Pigpen Cipher". It relies on visual aid to create the ciphertext itself but can be encoded and decoded mentally. Pext is set apart from these other tech- niques because it is extended to support a larger variety of symbols and alphanumeric characters. This is meant to be written in a physical medium. Not digitally. - Alphabetic Characters \ A / \ E / I | J | K R | S | T \•/ \ / •| • |• | | D •X• B H X F ---+---+--- ---+---+--- /•\ / \ L |M •|• N U | V | W / C \ / G \ ---+---+--- ---+---+--- •| • |• | | O | P | Q X | Y | Z - Numeric Characters • | • | • 1| 2 |3 ---+---+--- ,---, • 4|• 5|6 • | / | = 0 ---+---+--- '---' 7| 8 |9 • | • | • - Symbols _____ _____ |\ + /| |\ . /| | \ / | | \•/ | /\ |( X )| |!•X•,| \/ = Space | / \ | | /•\ | | | = New Paragraph |/ - \| |/ ? \| ''''''' ''''''' - All Other Unlisted Characters For all of the unassigned/unlisted characters, you can ei- ther create your own visual encryption method, or use the described procedure below. Basically, all you do is put your encrypted text be- tween both an encrypted "F" and "H" (making the markup brackets "<" and ">"). You place an abbreviated form of the symbol and place it between the brackets. For example, we'll use a slash. The abbreviated form of "slash" will be "slsh". Placing brackets on the outside of "slsh" will look like this: ___ / | | | | | \ \ < | | O| | | > > \ |___| ___| |___| / / You'll always be able to tell if there's a symbol in the document if there is any bracketed words. Although, it could be confused with words starting with an "F" and end- ing with an "H". Be careful if you come across words like "flash" or "fish". Here's a list of abbreviations: - : = cln - ; = scol - & = and - Λ = lamb - $ = dol - % = per - £ = pnd - ¥ = yen - # = hsh - ^ = crt - @ = at - * = as - _ = und - ` = apo - / = slsh - \ = hsls - ~ = tld - ' = quo1 - ฿ = btc - " = quo2 - Example Let's select a simple message to encrypt: Go forward. So we go by our visual aids to come up with: ___ ___ ___ ______ /\ O| /\ / O| | | \ / | \ \ / / \ | < > < | | | \()/ | o> \()/ / \ | \/ \ | ___| |___ \/ ___| / \/ If you want to decrypt it, just do the reverse. - Conclusion So, all in all, if you want to play around with this and make it as secure as possible, be my guest. All this is is an extended modification of an existing encryption method. You can make your own symbols or even just mix the exist- ing characters around with eachother. It is fairly easy to memorize, as I was able to recall the entire alphabet just a day after writing it down for the first time. ~ Kyro ~ - - - - - - - - - - - - End [8:58 AM, 5/6/2014]
