To encipher your own messages in python, you can use the pycipher module. To install it, use pip install pycipher. To encipher messages with the Beaufort cipher (or another cipher, see here for documentation): Kahn, D (1973) The CodeBreakers. Macmillan: New York. Singh, Simon (2000).
Tool to decrypt/encrypt with Beaufort automatically. Beaufort Cipher is a variant of the Vigenere Cipher: rather than add the key to the plaintext, Beaufort subtract the plaintext to the key.

char* beaufort_decr(char* ciphertext,char* keyword); char* beaufort_encr(char plaintext[],char keyword[]){ int txtsize = strlen(plaintext), keysize = strlen(keyword), i, j;
Add a description, image, and links to the beaufort-cipher topic page so that developers can more easily learn about it. To associate your repository with the beaufort-cipher topic, visit your repo's landing page and select "manage topics." GitHub is where people build software.
How Beaufort works? We use a Vigenère method for the key, but change the method of resolving the ciphertext. For this we look along the top row for the plaintext letter, and then go down until we find the key, and then look along the row to the first column:
20 Αυγ 2020 · Beaufort is similar, but subtly different. This post will assume you are familiar with Vigenère. In the Beaufort cipher, we find the letter in the message on the edge of the grid (e.g. M), then go down to find the letter of the key, X, and finally we read off the encrypted letter, L.
