Struct nrf52810_hal::ccm::CcmData
source · #[repr(C)]pub struct CcmData { /* private fields */ }
Expand description
Data used for encryption/decryption.
It consists of a 128-bits key, a 39-bits counter, a direction bit and a 8-bytes initialization vector. There are some reserved bits in this structure, the total size is 33 bytes.
The NONCE vector (as specified by the Bluetooth Core Specification) will be generated by hardware based on this information.
Implementations§
source§impl CcmData
impl CcmData
sourcepub fn new(key: [u8; 16], initialization_vector: [u8; 8]) -> CcmData
pub fn new(key: [u8; 16], initialization_vector: [u8; 8]) -> CcmData
Creates a new CcmData
instance.
The direction bit and the counter value will be initialized to zero. Care must be taken when choosing an initialization vector, it must be sufficiently random.
sourcepub fn set_direction(&mut self, direction: bool)
pub fn set_direction(&mut self, direction: bool)
Updates the direction bit.
sourcepub fn increment_counter(&mut self)
pub fn increment_counter(&mut self)
Increments the counter. It will wrap around to zero at its maximum value.
sourcepub fn decrement_counter(&mut self)
pub fn decrement_counter(&mut self)
Decrements the counter if the current value is bigger than zero.
