Enum lpc55::bootloader::command::KeystoreOperation

#[repr(u8)]
pub enum KeystoreOperation {
    Enroll,
    SetKey {
        key: Key,
        data: Vec<u8>,
    },
    GenerateKey {
        key: Key,
        len: u32,
    },
    WriteNonVolatile,
    ReadNonVolatile,
    WriteKeystore,
    ReadKeystore,
}

This is the interface definition to a somewhat limited bootloader API, that then operates on the actual PFR data and PUF periphreal.

The operations Enroll, SetKey, GenerateKey create activation codes or key codes, which the bootloader keeps in RAM and only writes to PFR once WriteNonVolatile is called. If this is not done, on reboot, the PUF is unenrolled again, or the keys are not set anymore.

It doesn’t however seem possible to set/generate new keys after reboot without re-enrolling PUF, calling set/generate key results in a Generic(Fail). Calling ReadNonVolatile does not help; the author does not understand the effect of this command.

Trait Implementations

impl Clone for KeystoreOperation

fn clone(&self) -> KeystoreOperation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeystoreOperation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeystoreOperation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&KeystoreOperation> for u32

fn from(operation: &KeystoreOperation) -> Self

Converts to this type from the input type.

impl Hash for KeystoreOperation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KeystoreOperation

fn cmp(&self, other: &KeystoreOperation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<KeystoreOperation> for KeystoreOperation

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<KeystoreOperation> for KeystoreOperation

fn partial_cmp(&self, other: &KeystoreOperation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for KeystoreOperation

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

Serialize this value into the given Serde serializer.

impl Eq for KeystoreOperation

impl StructuralEq for KeystoreOperation
