Cipher Tool Ver. 4.3.6
Changelog:
-Fixed a minor error in the Columnar Transposition Cipher
With the Cipher Tool, users are able to utilize the encryption and decryption algorithms of several ciphers, including, but not limited to:
-Caesar Cipher
-Atbash Cipher
-Rail Fence Cipher
-Columnar Transposition Cipher
-Morse Code
-Vigenere Cipher
-Running Key Cipher
-Multi Cipher
Users are able to choose any of these six ciphers and encrypt and decrypt any message of their choosing. Overall, this application allows for the creation and unscrambling of secret messages such that only those with a certain integer key are able to interpret the messages.
As for the ciphers themselves, each one generally operates by taking in an integer key and a message and then scrambling or unscrambling that message to an extent determined by the integer key. How this key is exactly interpreted depends on which cipher algorithm is chosen by the user. This integer key is essentially the literal "key" to encryption and decryption of a message, given that the user knows which cipher algorithm was used in the first place.
