Functions
ATCA_STATUS	atcacert_read_device_loc (const atcacert_device_loc_t device_loc, uint8_t data)
	Read the data from a device location.

ATCA_STATUS	atcacert_read_device_loc_ext (ATCADevice device, const atcacert_device_loc_t device_loc, uint8_t data)
	Read the data from a device location.

ATCA_STATUS	atcacert_read_cert (const atcacert_def_t cert_def, const uint8_t ca_public_key[64], uint8_t cert, size_t *cert_size)
	Reads the certificate specified by the certificate definition from the ATECC508A device.

ATCA_STATUS	atcacert_read_cert_ext (ATCADevice device, const atcacert_def_t cert_def, const uint8_t ca_public_key[64], uint8_t cert, size_t *cert_size)
	Reads the certificate specified by the certificate definition from the ATECC508A device.

ATCA_STATUS	atcacert_write_cert (const atcacert_def_t cert_def, const uint8_t cert, size_t cert_size)
	Take a full certificate and write it to the ATECC508A device according to the certificate definition.

ATCA_STATUS	atcacert_write_cert_ext (ATCADevice device, const atcacert_def_t cert_def, const uint8_t cert, size_t cert_size)
	Take a full certificate and write it to the ATECC508A device according to the certificate definition.

ATCA_STATUS	atcacert_create_csr (const atcacert_def_t csr_def, uint8_t csr, size_t *csr_size)
	Creates a CSR specified by the CSR definition from the ATECC508A device. This process involves reading the dynamic CSR data from the device and combining it with the template found in the CSR definition, then signing it. Return the CSR int der format.

ATCA_STATUS	atcacert_create_csr_pem (const atcacert_def_t csr_def, char csr, size_t *csr_size)
	Creates a CSR specified by the CSR definition from the ATECC508A device. This process involves reading the dynamic CSR data from the device and combining it with the template found in the CSR definition, then signing it. Return the CSR int der format.

ATCA_STATUS	atcacert_get_response (uint8_t device_private_key_slot, const uint8_t challenge[32], uint8_t response[64])
	Calculates the response to a challenge sent from the host.

ATCA_STATUS	atcacert_read_subj_key_id (const atcacert_def_t *cert_def, uint8_t subj_key_id[20])
	Reads the subject key ID based on a certificate definition.

ATCA_STATUS	atcacert_read_subj_key_id_ext (ATCADevice device, const atcacert_def_t *cert_def, uint8_t subj_key_id[20])
	Reads the subject key ID based on a certificate definition.

ATCA_STATUS	atcacert_read_cert_size (const atcacert_def_t cert_def, size_t cert_size)
	Return the actual certificate size in bytes for a given cert def. Certificate can be variable size, so this gives the absolute buffer size when reading the certificates.

ATCA_STATUS	atcacert_read_cert_size_ext (ATCADevice device, const atcacert_def_t cert_def, size_t cert_size)
	Return the actual certificate size in bytes for a given cert def. Certificate can be variable size, so this gives the absolute buffer size when reading the certificates.
