Detailed Description

Crypto APIs.

Macro Definition Documentation

CAP_ASYNC_OPS

#define CAP_ASYNC_OPS   BIT(6)

#include <include/zephyr/crypto/crypto.h>

CAP_AUTONONCE

#define CAP_AUTONONCE   BIT(7)

#include <include/zephyr/crypto/crypto.h>

Whether the hardware/driver supports autononce feature

CAP_INPLACE_OPS

#define CAP_INPLACE_OPS   BIT(3)

#include <include/zephyr/crypto/crypto.h>

Whether the output is placed in separate buffer or not

CAP_KEY_LOADING_API

#define CAP_KEY_LOADING_API   BIT(2)

#include <include/zephyr/crypto/crypto.h>

CAP_NO_IV_PREFIX

#define CAP_NO_IV_PREFIX   BIT(8)

#include <include/zephyr/crypto/crypto.h>

Don't prefix IV to cipher blocks

CAP_OPAQUE_KEY_HNDL

#define CAP_OPAQUE_KEY_HNDL   BIT(0)

#include <include/zephyr/crypto/crypto.h>

CAP_RAW_KEY

#define CAP_RAW_KEY   BIT(1)

#include <include/zephyr/crypto/crypto.h>

CAP_SEPARATE_IO_BUFS

#define CAP_SEPARATE_IO_BUFS   BIT(4)

#include <include/zephyr/crypto/crypto.h>

CAP_SYNC_OPS

#define CAP_SYNC_OPS   BIT(5)

#include <include/zephyr/crypto/crypto.h>

These denotes if the output (completion of a cipher_xxx_op) is conveyed by the op function returning, or it is conveyed by an async notification

Function Documentation

crypto_query_hwcaps()

static int crypto_query_hwcaps ( const struct device *  dev )

inlinestatic

#include <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.
