Detailed Description

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

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

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.

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.

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.
