Secure Hashing Algorithm (SHA) is an algorithm for generating cryptographically secure one-way hash, published by the National Institute of Standards and Technology as a U. S. Federal Information Processing Standard. What is the block (word) size used by SHA-512 algorithm?

32-bit

64-bit

128-bit

256-bit

64 byte.

It's not bit is byte.

Explanation:

Secure Hash Algorithms (SHA) : - These are a family of cryptographic hash functions. There are basically four types of secure hash algorithms for generating cryptographically secure one-way hash. They are as following:-

SHA-0

SHA-1

SHA-2

SHA-3

SHA - 2 consists of SHA-512 and the block size used by it is 64 byte or 512 bits.
