SHA-384 rs-sha384 - Secure Hash Algorithm 384

The SHA-384 hash function is part of the SHA-2 family, which was developed by the National Institute of Standards and Technology (NIST). SHA-384 provides a higher level of security than SHA-1 and SHA-256, producing a 384-bit hash from input data.

Usage

The crate provides a simple and intuitive API. Users can create a new SHA-384 hasher instance, update it with input data, and finalize to get the resultant hash.

Example

Here is an example of how to use the SHA-384 hash function in Rust:

# use std::hash::{BuildHasher, Hasher};
# use rs_sha384::Sha384State;
let mut sha384hasher = Sha384State::default().build_hasher();
sha384hasher.write(b"hello world");
let result = sha384hasher.finish();
assert_eq!(result, 0xA7FFE9F7385E2E23);

Or, as a HashSet:

# use std::{
#     collections::HashSet,
#     hash::{BuildHasher, Hash, Hasher}
# };
# use rs_sha384::Sha384Hasher;
let hello = "hello";
let mut sha384hasher1 = Sha384Hasher::default();
let mut sha384hasher2 = Sha384Hasher::default();
let mut sha384hasher3 = Sha384Hasher::default();

sha384hasher1.write(hello.as_bytes());
hello.hash(&mut sha384hasher2);
sha384hasher3.write(hello.as_bytes());
sha384hasher3.write(&[0xFF]);

let u64result1 = sha384hasher1.finish();
let u64result2 = sha384hasher2.finish();
let u64result3 = sha384hasher3.finish();

assert_eq!(u64result1, 0xFF6F8C6D7A33BBFB);
assert_eq!(u64result2, 0xF7FBF5FBC24F22D3);
assert_eq!(u64result2, u64result3);
assert_ne!(u64result1, u64result2);

Use Cases

SHA-384 is recommended for most cryptographic security applications and is commonly used in various fields such as:

• Digital signatures and certificate authorities which require a higher level of security.
• Cryptographic hardware and software standards that require a strong hash function.

NIST recommends the use of SHA-384 for security functions due to its resistance to collision attacks and its higher security level than SHA-1 and SHA-256. SHA-384 is thus widely used and considered safe for cryptographic and even most non-cryptographic functions
