Valen-H / Caesar

A file encryptor with caesar cipher algorithm.

Caesar

Caesar is a file encryptor tool inspired by the Caesar-Cipher wheel.

How it works

It simply shifts characters by key.
e.g: value : test, key : 1 => value : uftu, key : 1

Usage

• Terminal : mode=cipher|decipher key=1 file=... safe=false wheel=ASCII|HEX|"abcd..." npm start where safe is a boolean which controls whether character that does not belong to the wheel passed will be encrypted by the default wheel [Symbol('ASCII')]. wheel is a string containing all encryption characters in row, characters that do not appear in there will not be encrypted if safe is 'false'. Other formats : file=... npm run cipher file.txt, npm run start file key mode wheel safe.
• Binary : run npm test to install module globally and get access to cc file command which is the same as 'Terminal Run'.
• Module : the Caesar class contains the following : 3 static methods : cipher(value, key[, wheel, safe]), decipher(value, key[, wheel, safe]), fromFile(path) //<- returns a Caesar object that emits 'ready' and 'saved' events on itself. Instances have the following methods : cipher(key), cipher(value, key[, wheel, safe]), decipher(key), decipher(value, key[, wheel, safe]), toFile([path]) //<- specifying 'path' is not necessary for objects created with fromFile method.

Note that if you try to use instance operations on fromFile objects before they load ('ready'), they emit a 'fail' event on themselves and the global
