Snerx Strip Cipher (SSC)

Webend viewable here - https://snerx.com/SSC/

This is the code implimentation of the modified strip cipher from here - https://docs.google.com/spreadsheets/d/1O_KBJoCWQsLkmNv3VTzn41yg-RPXI7LdvSBxUnLTmiQ/

Play with it

This makes a key, encrypts a string into a message, and decrypts that message back into a string # node strip.js (strip takes same params as makeKey)

Command Line Interface

Make your key (range defaults to 394) # node makeKey.js [range] [languages/frequency_en.json] [languages/charset_en.json] > key

Use the key to encode your message # node encrypt.js key "this is my message" > msg

Use the key to decode your message # node decrypt.js key < msg

Use message and the plain text equivalent to try to reverse the key # node bruteKey.js inputKey "this is my message" < msg > outputKey

Tailor frequencies for specific plain text # node adjustFrequnecy.js "Adjust the frequencies" < languages/frequency_en.json > frequency_custom.json

API

charset2homophones(frequency set, character set, range of result homophone symbols) returns a letter to homephone mapping

encrypt(plaintext, letter to homophones map) returns an array of all homophones

decrypt(cipher, letter to homophones map) decodes homophones back into original message

extractHomophones(plaintext, cipher, frequency set) return updated frequency set

adjustFrequency(frequency set, plaintext, scale) return updated frequency set
