A program to encrypt and decrypt vigenere ciphers
This is a small Python 3 program I wrote that can encrypt and decrypt vigenere ciphers. You have a few command options in the terminal when you run the program.
encrypt [ciphertext] - encrypt a block of text, which you enter after inputting the ciphertext
decrypt [ciphertext] - decrypt a block of text, which you enter after inputting the ciphertext
help - output a help menu, which looks just like this
When you type encrypt or decrypt, you need to type the key immediately after it. After you hit enter, the program will ask you for the message/ciphertext you want to encrypt/decrypt. An example command would look like
encrypt key
Please enter your message
hello
and should output rijvs.
