Field Documentation

key

uint8_t cy_stc_ble_aes_ccm_decrypt_info_t::key[CY_BLE_ENCRYPTION_KEY_SIZE]

Array of bytes holding the key.

The key must be stored in little endian format.

nonce

uint8_t cy_stc_ble_aes_ccm_decrypt_info_t::nonce[CY_BLE_ENCRYPTION_NONCE_SIZE]

Array of bytes holding the nonce.

The nonce should be in CCM nonce format specified by the Bluetooth Core 5.0 Specification, Vol.6, Part E, Section 2.1.

data

uint8_t* cy_stc_ble_aes_ccm_decrypt_info_t::data

Pointer to an array of bytes to be encrypted.

Size of the array should be equal to the value of the 'length' parameter. The data must be stored in little endian format.
