Struct PinState 

pub struct PinState {
    pub pin_hash: Option<SecPinHash>,
    pub retries: u8,
    pub uv_retries: u8,
    pub min_pin_length: u8,
    pub version: u64,
    pub force_pin_change: bool,
}

Persistent PIN state for secure storage

Fields

pin_hash: Option<SecPinHash>

SHA-256 hash of the PIN (None if no PIN set)

retries: u8

Remaining PIN retry attempts (0-8)

uv_retries: u8

Remaining UV retry attempts (0-3)

This is persisted to prevent brute-force bypass via device restart. Uses serde default for backwards compatibility with existing stored state.

min_pin_length: u8

Minimum PIN length in Unicode code points (4-63)

version: u64

State version for rollback detection

force_pin_change: bool

Force PIN change flag

Implementations

impl PinState

pub fn new() -> PinState

Create a new PIN state with no PIN set

pub fn is_pin_set(&self) -> bool

Check if a PIN has been set

pub fn is_blocked(&self) -> bool

Check if PIN is blocked (no retries remaining)

pub fn is_uv_blocked(&self) -> bool

Check if UV is blocked (no UV retries remaining)

pub fn increment_version(&mut self)

Increment version for state change
