How can cipher text be converted into plain text?
no
How can you convert cipher text into plain text?
No
What is the Definition of encryption according to cryptography?
Encryption is the process by which the plain text is converted to cipher text. it is done at the sender's end before sending the message.
What are plain text and cipher text?
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.
Is encryption crackable?
Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.
What is the definition for encription?
the process of changing plain text (your information) into cipher text (secret message) so that no other can't understand it.
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".
Why do some block cipher modes of operation only use encryption while others use both encryption and decryption?
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.
How do you explain encryption?
Encryption is the process of converting your documents that are in plain text to cipher text. As the encrypted data is not readable by majority of hackers, therefore it becomes impossible for them to decipher it.
What is a practical method of finding a triple of keys that maps a given plain text to a given cipher text using EDE?
c = ek1(dk2(ek3(p)) dk1(c)= dk2(ek3(p)) If you decrypt c with a random key and store in a table of size n Try k2 and k3 and see if the result is in the table. If the result is in the table you are done. 64 bit text resulting in a 64 bit cipher The probability of it being in the table is n/264 The number of trials is 264/n Larger storage n => Less trials n = 232 => 232 trials Solution By: Raj Jain Washington University in St. Louis 6-34 Posted By Qasim Siddique Department of Computer Science FUIEMS
Antomyn for a cipher?
"Cipher" means: 1 a zero, hence any numeral; 2 a code or its key; 3 an unimportant person. An antonym for sense 2 is a plain text and for sense 3 a "somebody," a big-wig or honcho.
What is used to replaces each character in the plain text with a different letter by shifting the alphabet a certain number of positions?
That's what's known as a simple transposition cipher.
