Struct SecPinHash 

pub struct SecPinHash { /* private fields */ }

Secure PIN hash storage (32-byte SHA-256 hash)

Provides automatic memory zeroing on drop and constant-time comparison.

Implementations

impl SecPinHash

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

Create from a 32-byte PIN hash

pub fn from_slice(slice: &[u8]) -> Self

Create from a slice (panics if not exactly 32 bytes)

pub fn verify(&self, expected: &[u8]) -> bool

Verify PIN hash using constant-time comparison

pub fn verify_first_16(&self, expected: &[u8]) -> bool

Verify first 16 bytes (per CTAP spec for PIN verification)

pub fn as_array(&self) -> [u8; 32]

Get the full 32-byte hash

pub fn with_bytes<F, R>(&self, f: F) -> R

where F: FnOnce(&[u8; 32]) -> R,

Perform operation with protected scope

Trait Implementations

impl Clone for SecPinHash

fn clone(&self) -> SecPinHash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SecPinHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SecPinHash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<SecPinHash> for SecBytes

fn from(hash: SecPinHash) -> Self

Converts to this type from the input type.

impl PartialEq for SecPinHash

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SecPinHash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<SecBytes> for SecPinHash

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(bytes: SecBytes) -> Result<Self, Self::Error>

Performs the conversion.
