Function Documentation

◆ crypto_query_hwcaps()

static int crypto_query_hwcaps ( const struct device * dev)
inlinestatic

#include <zephyr/crypto/crypto.h>

Query the crypto hardware capabilities.

This API is used by the app to query the capabilities supported by the crypto device. Based on this the app can specify a subset of the supported options to be honored for a session during cipher_begin_session().

Parameters
devPointer to the device structure for the driver instance.
Returns
bitmask of supported options.
