Public Methods

void Clear ()

Clears the stored keys and key index.

const KeyMaterial & GetKey (Type aType)

Gets a MAC key of a given type from the trio.

aType [in] The key type (`kPrev`, `kCur`, or `kNext`).

Defined at line 679 of file ../../third_party/openthread/src/core/mac/mac_types.hpp

uint8_t GetKeyIndex ()

Gets the MAC key index.

Defined at line 686 of file ../../third_party/openthread/src/core/mac/mac_types.hpp

const KeyMaterial & SelectKey (uint8_t aKeyIndex)

Selects the MAC key from the trio for a given key index.

This method always returns a valid key. If the given key index matches the current, previous, or next key index

in the trio, the corresponding key material is returned. If the given key index does not match any of these,

the current key material is returned by default. This is a safety precaution to ensure that any frame with

security enabled is encrypted using a valid key.

aKeyIndex [in] The key index to select.

enum Type : uint8_t

Represents the key type (previous, current, or next).
