The Substitute

Solution from Last Time: In our last post, we used the Caesar Cipher with a shift of three to decode the following message: K H O O R D Q G Z H O F R P H W R F R G H E U H D N L Q J Applying a shift of three places to the left, the hidden message was: “HELLO AND WELCOME TO CODE BREAKER” Great job to everyone who cracked the code! Today's Cipher Challenge: We’re exploring a new puzzle today with the   Substitution Cipher , a method where each letter in the plaintext is replaced with another letter from a fixed substitution alphabet. The Encrypted Message: Z B W F Y X R L D K V O E P J N I Q C A M U H G T S Background: In the Substitution Cipher, each letter in the plaintext is substituted with a letter from a fixed, randomly shuffled alphabet. For this challenge, we’re using the following substitution alphabet: Plaintext Alphabet:   ABCDEFGHIJKLMNOPQRSTUVWXYZ Substitution Alphabet:   XPMGJWLZVNTSBDFHCRQOIEAKUY Decoding Instructions: Identify the Substitution Alphabet: ...

The Vigenère

  Welcome back! Today, we're unraveling a new cipher with our Code of the Day. The Encrypted Message: SNCRDSZR SGQDDQ ZDR QDRS ENQ VQDDSHMF Background: Today's cryptographic challenge uses the Vigenère Cipher, a method of encrypting alphabetic text by using a simple form of polyalphabetic substitution. This cipher was named after Blaise de Vigenère, a French diplomat. It employs a keyword to determine the shift for each letter, integrating the simplicity of the Caesar Cipher with a more robust and unpredictable approach. Decoding Instructions: Identify the Keyword : The keyword is repeated until it matches the length of the message. For example, if the keyword is "KEY", it would be repeated like this: KEYKEYKEYK. Determine the Shift : Each letter of the keyword corresponds to a shift value, where 'A' shifts 0, 'B' shifts 1, and so on. For "KEY", 'K' represents a shift of 10, 'E' represents 4, and 'Y' represents ...

The Caesar Cipher

Welcome back! Today, we’re looking at our first cipher, starting with the Code of the Day. The Encrypted Message: Copy K H O O R D Q G Z H O F R P H W R F R G H E U H D N L Q J Background: This puzzle uses a simple yet effective cryptographic method known as the Caesar Cipher, named after Julius Caesar, who used it to communicate with his officials. The Caesar Cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet. For this puzzle, we’ll use a shift of three places to the right. Decoding Instructions: Identify the Shift : For a Caesar Cipher with a shift of two, each letter in the encrypted message moves two places to the left in the alphabet. For example, ‘C’ becomes ‘A,’ ‘D’ becomes ‘B,’ and so on. Apply the Shift : Take each letter in the encrypted message and shift it three places to the left to reveal the plaintext. Reveal the message : Once you've shifted each letter, the hidden message will be revealed...
