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

dev	Pointer to the device structure for the driver instance.

Returns

bitmask of supported options.
