SHA-512¶

Module: Std::Hash::Sha512

512-bit SHA-2 cryptographic hash.

Summary¶

struct Sha512

Sha512.Hash(message: char8[]) -> String

Constants¶

Constant	Value
`BlockSize`	128
`DigestSize`	64

Description¶

SHA-512 is a 512-bit hash function from the SHA-2 family, published by NIST in 2001. It uses a Merkle–Damgård construction with a Davies–Meyer compression function, processing 1024-bit blocks through 80 rounds. The algorithm operates on 64-bit words with bitwise operations, modular addition, and eight working state variables.

SHA-512 remains cryptographically secure and is widely recommended for applications requiring a larger digest size.

The Hash method takes a char8[] and returns a hex-encoded digest string.

Example¶

import Std::Hash::Sha512;

func Main() {
    let digest = Sha512::Hash(c8"abc");
    PrintLine(digest);
    // ddaf35a193617abacc417349ae20413112e6fa4e89a97ea20a9eeee64b55d39a2192992a274fc1a836ba3c23a3feebbd454d4423643ce80e2a9ac94fa54ca49f
}
