Hi, can anyone explain me how to retrieve the result of the aes_encrypt function, please?
I tryed to follow the example of the library, but i don't understand how to get the encrypted data from the handle function, thanks.
The library is inside the SDK and its name is aes.h.
typedef void (aes_func_result_cb) (uint8_t status, const uint8_t aes_res, uint32_t src_info);
/*

/*********************************************************************
@fn aes_encrypt
@brief Perform an AES encryption - result within callback
Sample:
const uint8_t key[] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x00};
const uint8_t value[] = {0x11, 0x22, 0x33, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0xee, 0x0f, 0xaa};
aes_encrypt(key, value, true, aes_enc_result_cb, 0);
@param key - Key used for the encryption
val - Value to encrypt using AES
copy - Copy parameters because source is destroyed
res_cb - Function that will handle the AES based result (16 bytes)
src_info - Information used retrieve requester
@return None.
