Functions
ATCA_STATUS	atcacert_get_subject (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, cal_buffer *cert_subj_buf)
	Gets the subject name from a certificate.
ATCA_STATUS	atcacert_get_subj_public_key (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, cal_buffer *subj_public_key)
	Gets the subject public key from a certificate.
ATCA_STATUS	atcacert_get_subj_key_id (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, uint8_t subj_key_id[20])
	Gets the subject key ID from a certificate.
ATCA_STATUS	atcacert_get_issuer (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, uint8_t cert_issuer[128])
	Gets the issuer name of a certificate.
ATCA_STATUS	atcacert_get_issue_date (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, atcacert_tm_utc_t *timestamp)
	Gets the issue date from a certificate. Will be parsed according to the date format specified in the certificate definition.

	Gets the expire date from a certificate. Will be parsed according to the date format specified in the certificate definition.
ATCA_STATUS	atcacert_get_cert_sn (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, uint8_t *cert_sn, size_t *cert_sn_size)
	Gets the certificate serial number from a certificate.
ATCA_STATUS	atcacert_get_auth_key_id (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, uint8_t auth_key_id[20])
	Gets the authority key ID from a certificate.
int	atcacert_calc_expire_years (const atcacert_def_t *cert_def, const uint8_t *cert, size_t cert_size, int issue_tm_year, uint8_t *expire_years)
