Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.
It is the atbash cipher answer: scroll
You mean your plaintext message the yes you can but you have to separate it with an x when you put letters in pairs, but in a key no.
Some block cipher modes of operation only use encryption because the input is set to some initialization vector and the leftmost bits of the output of the encryption function are XORed with the first segment of plain text p1 to produce the first unit of cipher text C1 and it is transmitted. While in decryption, the cipher text is XORed with the output of the encryption function to produce the plain text.
Stream cipher is one that encrypts a digital data stream one bit or one byte at a timeBlock cipher is one in which a block of plaintext is treated as a whole n used to produce a ciphertext block of equal lengthhmmmmmmm got it!!!
the process of changing plain text (your information) into cipher text (secret message) so that no other can't understand it.
The cipher "0" is commonly known as the "null cipher" and the "zero cipher." A null cipher encodes a message by hiding it within a larger body of text, often using specific letters or words to reveal the intended message, while the zero cipher is a more general term that can refer to any encoding that represents information with no visible changes in a certain context.
The Playfair Cipher is useful because it requires no special equipment to use. However, it was invented in 1854 and is antiquated and rarely used in the present.
Plain text is a simple text which is written without any formating. Whereas, Cypher is an algorithm used in cryptography to encrypt the plain text and resulting/encyypted text is called as Ciphertext.
