- 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 text written in cipher or code called?
Text written in cipher or code is called "ciphertext." This type of text is transformed from its original form, known as "plaintext," using a specific algorithm or key, making it unreadable without the appropriate decryption method. Ciphertext is commonly used in cryptography to secure sensitive information from unauthorized access.
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.

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"
Is a programmed formula that the originator of the data uses to encrypt the plain text and the recipient of the data uses to decrypt the cipher text?
Yes, a programmed formula used for encryption and decryption is known as an algorithm. In this context, the originator of the data applies the encryption algorithm to transform plain text into cipher text, while the recipient employs the same or a corresponding decryption algorithm to revert the cipher text back to its original plain text form. This process ensures that only authorized parties can access the readable data.
What is The essential ingredients of symmetric cipher?
The essential ingredients of a symmetric cipher include a secret key, an encryption algorithm, and a decryption algorithm. The secret key is shared between the sender and receiver and is used to encrypt and decrypt the data. The encryption algorithm transforms plaintext into ciphertext using the key, while the decryption algorithm reverses this process, converting ciphertext back into plaintext using the same key. Security relies on the secrecy of the key, as anyone with access to it can decrypt the data.

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.
