bool	nrf_ecb_crypt (uint8_t *dst, const uint8_t *src)
void	nrf_ecb_set_key (const uint8_t *key)

Detailed Description

In order to encrypt and decrypt data the peripheral must be powered on using nrf_ecb_init() and then the key set using nrf_ecb_set_key.

Function Documentation

bool nrf_ecb_init

(

void

)

Initialize and power on the ECB peripheral.

Allocates memory for the ECBDATAPTR.

Return values

true	Initialization was successful.
false	Powering up failed.

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

Encrypt/decrypt 16-byte data using current key.

The function avoids unnecessary copying of data if the 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.

void nrf_ecb_set_key

(

const uint8_t *

key

)

Set the key to be used for encryption/decryption.

Parameters

key	Pointer to key. 16 bytes will be read.
