Detailed Description

Driver for the nRF51 AES Electronic Code Book (ECB) peripheral.

To encrypt and decrypt data, the peripheral must first be powered on using nrf_ecb_init. Next, the key must be set using nrf_ecb_set_key.

Function Documentation

bool nrf_ecb_crypt	(	uint8_t *	dst,
		const uint8_t *	src
	)

Function for encrypting and decrypting 16-byte data using current key.

This function avoids unnecessary copying of data if the parameters point to the correct locations in the ECB data structure.

Parameters

dst	Result of encryption/decryption. 16 bytes will be written.
src	Source with 16-byte data to be encrypted/decrypted.

Return values

true	If the encryption operation completed.
false	If the encryption operation did not complete.

bool nrf_ecb_init

(

void

)

Function for initializing and powering on the ECB peripheral.

This function allocates memory for the ECBDATAPTR.

Return values

true	If initialization was successful.
false	If powering on failed.

void nrf_ecb_set_key

(

const uint8_t *

key

)

Function for setting the key to be used for encryption and decryption.

Parameters

key	Pointer to the key. 16 bytes will be read.
