Key Concepts

Vigenère Cipher

The Vigenère cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers based on the letters of a keyword. It is a type of polyalphabetic substitution cipher, meaning it uses multiple substitution alphabets to increase security against simple frequency analysis.

Keyword

In the context of the Vigenère cipher, a keyword is a word or phrase that determines the sequence of shifts used in the encryption process. Each letter in the keyword corresponds to a specific shift amount, and the keyword is repeated as necessary to cover the entire plaintext during encryption.

Plaintext

Plaintext refers to the original unencrypted message that is input into the encryption algorithm. In encryption processes like the Vigenère cipher, the plaintext is transformed into ciphertext by applying systematic shifts based on the chosen key.

Encryption

Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) to ensure that the data remains private and secure from unauthorized access. It is a fundamental concept in securing communication and information.
