Question

What basic arithmetical and logical functions are used in SHA?​

Answer 1

Answer:

bitwise operations, modular additions, and compression functions

Answer 2

Answer:

Circular shifts, AND, OR, NOT and XOR is the basic arithmetical and logical functions are used in SHA.

Explanation:

Secure Hash Algorithm (SHA) is a hashing algorithm that is used to hash data and certificate files. Every piece of data generates a unique hash that is completely indistinguishable from that of any other piece of data. The resulting digital signature is also one-of-a-kind because it is based on the hash generated from the data.

Secure Hash Algorithms, or SHA, are a group of cryptographic functions that are used to keep data secure. It works by transforming data with a hash function, which is a bitwise operations, modular additions, and compression functions-based algorithm.

• The Secure Hash Algorithm $1$, or SHA$-1$, was created by the National Institute of Standards and Technology in the United States in $1993$. (NIST).

• TLS, SSL, PGP, SSH, IPsec, and S/MIME are just a few of the security applications and protocols that use it.

• Secure hashing algorithm (SHA) is an acronym for secure hashing algorithm.
• SHA is a hashing algorithm that is based on MD$5$. It is used to hash data and certificates.
• Using bitwise operations, modular additions, and compression functions, a hashing algorithm compresses the input data into a smaller form that cannot be understood.
