The total length of the message after padding and adding length representation in SHA 512 is ____
|
|
L x 512 bits
|
|
|
L x 1024 bits
|
|
|
L x 1028 bits
|
|
|
L x 128 bits
|
Explanation:
Detailed explanation-1: -4. What is the maximum length of the message (in bits) that can be taken by SHA-512? Explanation: The maximum length of the message is 2128. Explanation: Padding is done so that the length is 896 mod 1024.
Detailed explanation-2: -Message Length: The length of the cleartext should be less than 264 bits. The size needs to be in the comparison area to keep the digest as random as possible. Digest Length: The length of the hash digest should be 256 bits in SHA 256 algorithm, 512 bits in SHA-512, and so on.
