Functions
ATCA_STATUS	atcacert_der_enc_length (size_t length, uint8_t der_length, size_t der_length_size)
	Encode a length in DER format.

ATCA_STATUS	atcacert_der_dec_length (const uint8_t der_length, size_t der_length_size, size_t *length)
	Decode a DER format length.

ATCA_STATUS	atcacert_der_adjust_length (uint8_t der_length, size_t der_length_size, int delta_length, size_t *new_length)

ATCA_STATUS	atcacert_der_enc_integer (const uint8_t int_data, size_t int_data_size, uint8_t is_unsigned, uint8_t der_int, size_t *der_int_size)
	Encode an ASN.1 integer in DER format, including tag and length fields.

ATCA_STATUS	atcacert_der_dec_integer (const uint8_t der_int, size_t der_int_size, uint8_t int_data, size_t int_data_size)
	Decode an ASN.1 DER encoded integer.

ATCA_STATUS	atcacert_der_enc_ecdsa_sig_value (const uint8_t raw_sig[64], uint8_t der_sig, size_t der_sig_size)
	Formats a raw ECDSA P256 signature in the DER encoding found in X.509 certificates.
