SWS^1.0

Letter frequency analysis is used for decrypting substituion ciphers by comparing cipher letter frequencies with plain text English letter frequencies.

• Run App

A Caesar cipher only has 25 possibly combinations for its cipher key. Generating them all is trivial, making a brute force method simple to implement for decrypting.

• Run App

An app that will take plain text and encrypt it using a Caesar Cipher (also known as a shift cipher).

A Caesar cipher or shift cipher replaces each letter in the plain text with a letter N steps down the alphabet. For example, A becomes D, and B becomes E when N = 3. A famous example of this today can be found with ROT13 (rotation 13), where N = 13, meaning the alphabet is split evenly down the middle.

• Run App

A simple app for converting text to and from binary.

Characters are first converted to the ASCII code (numeric) representation. This integer can then be converted to a 8 digit/character binary number. The same process is followed to convert back from binary, and requires that the binary string be a multiple of 8.
