Struct Sha256Hasher 

pub struct Sha256Hasher(/* private fields */);

Available on crate feature sha2 only.

SHA-256 Hasher.

The most common production hasher for audit-trail. SHA-256 is a FIPS 180-4 standard primitive, 32-byte output, widely accepted by HIPAA, SOC 2, PCI-DSS, and other compliance frameworks.

Example

use audit_trail::{Digest, Hasher, Sha256Hasher};

let mut hasher = Sha256Hasher::new();
hasher.update(b"audit-trail");
let mut out = Digest::ZERO;
hasher.finalize(&mut out);
// SHA-256("audit-trail") = 4e9b…
assert_ne!(out, Digest::ZERO);
