SHA-512 rs_sha512 - Secure Hash Algorithm 512

The SHA-512 hash function is part of the SHA-2 family, which was developed by the National Institute of Standards and Technology (NIST). It is commonly used for cryptographic security, providing a significantly higher security margin than SHA-1 and SHA-256.


The crate provides a simple and intuitive API. Users can create a new SHA-512 hasher instance, update it with input data, and finalize to get the resultant hash.


Here is an example of how to use the SHA-512 hash function in Rust:

let mut sha512hasher = Sha512State::default().build_hasher();
sha512hasher.write(b"hello world");
let u64result = sha512hasher.finish();
let bytes_result = HasherContext::finish(&mut sha512hasher);
assert_eq!(u64result, 0x309ECC489C12D6EB);
        0x30, 0x9E, 0xCC, 0x48, 0x9C, 0x12, 0xD6, 0xEB, 0x4C, 0xC4, 0x0F, 0x50, 0xC9, 0x02, 0xF2, 0xB4, 0xD0, 0xED,
        0x77, 0xEE, 0x51, 0x1A, 0x7C, 0x7A, 0x9B, 0xCD, 0x3C, 0xA8, 0x6D, 0x4C, 0xD8, 0x6F, 0x98, 0x9D, 0xD3, 0x5B,
        0xC5, 0xFF, 0x49, 0x96, 0x70, 0xDA, 0x34, 0x25, 0x5B, 0x45, 0xB0, 0xCF, 0xD8, 0x30, 0xE8, 0x1F, 0x60, 0x5D,
        0xCF, 0x7D, 0xC5, 0x54, 0x2E, 0x93, 0xAE, 0x9C, 0xD7, 0x6F

Or, as a HashSet:

let hello = "hello";
let mut sha512hasher1 = Sha512Hasher::default();
let mut sha512hasher2 = Sha512Hasher::default();
let mut sha512hasher3 = Sha512Hasher::default();

hello.hash(&mut sha512hasher2);

let u64result1 = sha512hasher1.finish();
let u64result2 = sha512hasher2.finish();
let u64result3 = sha512hasher3.finish();

assert_eq!(u64result1, 0x9B71D224BD62F378);
assert_eq!(u64result2, 0x186CCD043395B8D8);
assert_eq!(u64result2, u64result3);
assert_ne!(u64result1, u64result2)

Use Cases

SHA-512 is suitable for a wide range of applications, including but not limited to:

  • Digital Signatures and Certificate authorities: for ensuring the authenticity of digital assets.
  • Password Storage: it is often used in password hashing schemes, such as bcrypt, scrypt, and Argon2.
  • Ensuring the integrity of data transmitted over networks.

NIST recommends SHA-512 for cryptographic functions where a stronger security guarantee is required. In addition, SHA-512 is also often used for checksumming and fingerprinting.


  • Sha512Hasher is a type that provides the SHA-512 hashing algorithm in RustyShield.
  • Sha512State represents the state of a SHA-512 hashing process.


  • Overloads the finish Hasher method for a version that mutates itself
