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
dstResult of encryption/decryption. 16 bytes will be written.
srcSource with 16-byte data to be encrypted/decrypted.
Return values
trueIf the encryption operation completed.
falseIf 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
trueIf initialization was successful.
falseIf 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
keyPointer to the key. 16 bytes will be read.
