WebThe Vigenère cipher is an improvement of the Caesar cipher, by using a sequence of shifts instead of applying the same shift to every letter. A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. Gronsfeld ciphers can be solved as well through the Vigenère tool. WebThis term "cryptographically strong" is often used to describe an encryptionalgorithm, and implies, in comparison to some other algorithm (which is thus cryptographically weak), greater resistance to attack. But it can also be used to describe hashing and unique identifier and filename creation algorithms. fisheries resources of bangladesh

"WebSymmetric ciphers are commonly used to achieve other cryptographic primitives than just encryption. [citation needed] Encrypting a message does not guarantee that it will remain unchanged while encrypted. Hence, often a message authentication code is added to a ciphertext to ensure that changes to the ciphertext will be noted by the receiver. " - Cryptographic ciphers
