|
16 bits
|
|
|
64 bits
|

Explanation:
Detailed explanation-1: -SHA 512 consists of 8 words of 64 bits each. The standard hashing algorithm will run individual round for 80 times and the generates 512 bits output.
Detailed explanation-2: -The hash size for the SHA512 algorithm is 512 bits.
Detailed explanation-3: -A 512-bit buffer is used to hold intermediate and final results of the hash function. The buffer can be represented as eight 64-bit registers (a, b, c, d, e, f, g, h).
Detailed explanation-4: -SHA-512 has an output size of 512 bits.
