cosmic-angst:The way the Vigenére code works is by using the Vigenére table, the tabula recta, which I’ve provided above. Take the row in the table corresponding to the key, find the position of the ciphertext letter in this row, and then use the column’s label as the plaintext. Using the Scary-oke ciphertext and key I’ll show you how it worksSMOFZQA JDFVWIDDLEW IDDLSo, we look in the W row, find S in that row, and see what column letter that letter corresponds to in that row. In this case, it’s W. Next, we look in the I row, find M in that row, and the corresponding column letter is E. You continue that until you finish decoding the cipher. Doing that will get you the words: WELCOME BACK. -- source link
