Here is a deep dive into how this landmark algorithm works, its history, and why it eventually fell. What is the Vigenère Algorithm?

The Vigenère Cipher: Unlocking the "Indecipherable" Algorithm

Write the keyword repeatedly above the plaintext until it matches the length of the message. Find the Intersection: The letter from the plaintext determines the column . The letter from the keyword determines the row . The letter where they intersect is your ciphertext. Example: Plaintext: HELLO Keyword: KEY (repeated as KEYKE) Process: H + K = R E + E = I L + Y = J L + K = V O + E = S Result: RIJVS The Mathematical Formula
