Struct HmacGenerator 

pub struct HmacGenerator { /* private fields */ }

Deterministic replacement generator seeded with a 32-byte key.

replacement = format(category, HMAC-SHA256(key, category_tag || "\x00" || original))

The same key + same (category, original) always yields the same output. Different keys yield completely different outputs with overwhelming probability.

Implementations

impl HmacGenerator

pub fn new(key: [u8; 32]) -> Self

Create a new generator from a 32-byte seed.

pub fn from_slice(bytes: &[u8]) -> Result<Self>

Create a generator from a byte slice (must be exactly 32 bytes).

Errors

Returns SanitizeError::InvalidSeedLength if bytes.len() != 32.

Trait Implementations

impl Drop for HmacGenerator

fn drop(&mut self)

Executes the destructor for this type.

impl ReplacementGenerator for HmacGenerator

fn generate(&self, category: &Category, original: &str) -> String
