Struct SerializablePinState 

pub struct SerializablePinState {
    pub pin_hash: Option<Vec<u8>>,
    pub retries: u8,
    pub uv_retries: u8,
    pub min_pin_length: u8,

    pub credential_wrapping_generation: u64,
    pub locked_until: Option<u64>,
}

Serializable PIN state for storage (legacy, single-file format)

This struct represents the PIN state in a format suitable for serialization to JSON or other formats. It contains the PIN hash as raw bytes (if set), retry counters, and configuration.

Fields

pin_hash: Option<Vec<u8>>

PIN hash as raw bytes (None if no PIN set)

retries: u8

Remaining PIN retry attempts (0-8)

uv_retries: u8

Remaining UV retry attempts

The serde default of 3 maintains backward compatibility with existing stored state. The actual maximum is enforced by the configured pin.max_uv_retries value.

min_pin_length: u8

Minimum PIN length (4-63)

version: u64

State version for rollback detection

force_pin_change: bool

Force PIN change flag

credential_wrapping_generation: u64

Credential wrapping generation, incremented on reset to invalidate wrapped credentials

locked_until: Option<u64>

Auto-lock timestamp in milliseconds since Unix epoch (None = not locked)
