Answer:
Caesar cipher
Explanation:
In formation technology, cryptography or cryptology is a process of coding or encrypting information, using algorithms and input values in a network, where there is a present of a third party called adversaries or attackers.
There are different types of cryptography, namely, symmetric, assymmetric and hash cryptography.
Ciphers are algorithms used in cryptography to encode (encrypt) or decode (decrypt) information. An example of cipher is the Ceasar's cipher.
Ceasar cipher is a simple type of substitution cipher that encrpts plain text one character at a time and each coded character depends on the single character and a fixed distance value.
Answer:
The answer of the following question is Brute force attack
.
Explanation:
A brute force attack is the error and trial method that is used by an application program to decode the encrypted data like passwords or the Data Encryption Standard (DES) keys, which through an exhaustive effort (by using brute force) rather than the employing an intellectual strategies.
Answer:
3e : 00111110 (62)
3e0 : 0000001111100000 (992)
3e00 : 0011111000000000 (15872)
Explanation:
Converting the given hexadecimal numbers to binary and decimal format:
1) 3e
3-> 0011
e-> 1110
Combining , 3e -> 00111110
This can be converted to decimal by multiplying each 1 in the binary representation by 2^(position -1) and adding the results.
So 3e = 32+16+8+4+2 = 62
2) 3e0
Binary => 0000001111100000
Converting to decimal : 992 [ This is 16 times a]
3) 3e00
Binary => 0011111000000000
Converting to decimal : 15872 [ This is 16 times b]
So adding a 0 to the hex representation multiplies the decimal number by 16.
