- Hill Cipher is a cryptographic algorithm to encrypt and decrypt an alphabetic text. In this cipher, each letter is represented by a number (eg. A = 0, B = 1, C = 2). To encrypt a message, each block of n letters (considered as an n -component vector) is multiplied by an invertible n × n matrix, against modulus 26.

What is an Encryption algorithm that switches the order of characters?
A transposition cipher
What symmetric algorithm encrypts data one bit at a time?
Example of a stream cipher
What is key of hill cipher if we have plain text and cipher text?
Assume Plaintext = P, Ciphertext = C, and the Key = K. C = P * K Therefore, multiply both sides by the inverse of P and you will get: C * P^(-1) = K Or, (ciphertext) * (inverse plaintext) = key If the size of the key is known as well, then use that same size when creating P and C matrices.

Which encryption algorithm is commonly used as a public key cipher?
Type your answer here... RSA
What is a Xor cypher used for?
XOR cipher is a form of encryption algorithm. In simple terms, the cipher is used to decode binary language. For more details, Wikipedia is a great resource.
What is a cypher?
A cypher (or cipher) is an algorithm to render text or information encrypted and unreadable unless you have the cypher to decipher it.
What is the best encription algorithm for hand-coding and decoding?
There is the vigenère cipher, which is pretty strong but relativeley easy to "hand-code"
What is a common asymmetric cipher?
Pick one:l Diffie-Hellmanl RSAl Elliptic curvel ElGamall Digital Signature Algorithm (DSA)
What is the data called when it is to be encrypted by inputting into an algorithm called?
Before encryption, the data is referred to as "plain text". After encryption it is called "cipher text".
Could the ciphertext JOHN A1 be a valid ciphertext for the plaintext JOSE C1?
Of course it COULD be. Even a simple substitution cipher could be used to generate the given ciphertext from the given plaintext since they both have the same number of characters. Whether or not it actually IS a valid ciphertext depends on the algorithm used to encrypt it.
What is a another word for code and is a way to transform text in order to conceal its meaning?
In cryptography, a cipher (or cypher) is an algorithm for performing encryption and decryption of text.
Is not a type of cipher Substitution?
here are three different types of ciphers. Here are a couple of examples of simple ones:Substitution Cipher: Replace bits or bytes Example - Caesarian Cipher shift up 3The enemy is nigh = Wkh hqhpb lv qljkTransposition Cipher: Example - Transposition rotate three characters rightThe enemy is nigh = ene myisn ig htheSubstitution and Transposition (modern algorithm) The enemy is nigh = hqh pblvq lj kwkh
How is Data Encryption Standard work in details?
Data Encryption Standard is a symmetric-key algorithm for the encryption of electronic data. It is considered a block cipher because it uses an algorithm that takes a plaintext bits and transforms it through into another ciphertext bitstring of the same length
