【Exploit】 poly DL : 0: A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.

【Exploit】 Vigenere-Key-Method DL : 0: The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution.Though the cipher is easy to understand and implement, for three centuries it resisted all attempts to break it this earned it the description le chiffre indéchiffrable (French for the indecipherable cipher ). Many people have tried to implement encryption schemes that are essentially Vigenère ciphers.[3] Friedrich Kasiski was the first to publish a general method of deciphering a Vigenère cipher.Unlike the monoalphabetic ciphers, polyalphabetic ciphers are not susceptible to frequency analysis, as more than one letter in the plaintext can be represented by a single letter in the encryption.-The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword.

The initial it requires a 128-bit key and a 128-bit initialization vector (IV) as input, and output a string of 32-bit words of the Keystream (so, each 32-bit word here referred to as a key word). Key can be used for encryption/decryption. IV initialization, that is, the clock controls password runs but does not produce output.
