Struct Hasher 

pub struct Hasher { /* private fields */ }

API key hasher and issuer.

The HMAC key is validated and pre-initialized at construction time so that digest and compare are fully infallible at call time.

Implementations

impl Hasher

pub fn new(config: HashingConfig) -> AppResult<Self>

Construct a new hasher, validating config and pre-initializing the HMAC key.

pub const fn config(&self) -> &HashingConfig

Return the active configuration.

pub fn generate_key(&self, prefix: &str) -> AppResult<GenerateResult>

Generate a new API key with the supplied prefix.

pub fn digest(&self, plain_key: &str) -> String

Compute the peppered HMAC-SHA-256 digest for a plaintext key.

Infallible — the HMAC key was validated at construction.

pub fn compare(&self, plain_key: &str, stored_digest: &str) -> bool

Constant-time digest comparison.
