Explanation:

Vigenere coding is one of the most ancient forms of cryptography. In a Vigenere cipher, messages are encoded by mapping letters to numeric values and adding the plaintext values to the keytext values, modulo the number of letters in the alphabet. Despite its simplicity, the Vigenere cipher is capable of producing 100% crack-proof ciphers if used correctly. To produce an unbreakable cipher, you must:

Choose a key that is as long as the plaintext message.

Build the key from random characters.

Never use the key again.

Don't use text decorations (spaces, punctuations, capitalization). Cool villa with pool barcelona offers

Protect the key.

Unfortunately, these steps take all the fun out of the Vigenere cipher. Most people use English words or phrases for the key (violating step 2) that are significantly shorter than the message being coded (violating step 1). Then they use the same key to encrypt additional messages (violating step 3) because they don't want to remember a new key for each message. Some people use quotations from their favorite book for the key or invent one and write it down (violating step 5). Lastly, it's no fun to handle text that doesn't look like text, so they don't remove the decorations (violating step 4). The moral of the story is that security is free, but it requires effort.
