Classes
struct	mbedtls_asn1_buf

struct	mbedtls_asn1_bitstring

struct	mbedtls_asn1_sequence

struct	mbedtls_asn1_named_data

Macros
#define	MBEDTLS_OID_SIZE(x) (sizeof(x) - 1)

#define	MBEDTLS_OID_CMP(oid_str, oid_buf)

#define	MBEDTLS_OID_CMP_RAW(oid_str, oid_buf, oid_buf_len)

ASN1 Error codes
These error codes are combined with other error codes for higher error granularity. e.g. X.509 and PKCS #7 error codes ASN1 is a standard to specify data structures.
#define	MBEDTLS_ERR_ASN1_OUT_OF_DATA -0x0060

#define	MBEDTLS_ERR_ASN1_UNEXPECTED_TAG -0x0062

#define	MBEDTLS_ERR_ASN1_INVALID_LENGTH -0x0064

#define	MBEDTLS_ERR_ASN1_LENGTH_MISMATCH -0x0066

#define	MBEDTLS_ERR_ASN1_INVALID_DATA -0x0068

#define	MBEDTLS_ERR_ASN1_ALLOC_FAILED -0x006A

#define	MBEDTLS_ERR_ASN1_BUF_TOO_SMALL -0x006C

DER constants
These constants comply with the DER encoded ASN.1 type tags. DER encoding uses hexadecimal representation. An example DER sequence is: 0x02 – tag indicating INTEGER 0x01 – length in octets 0x05 – value Such sequences are typically read into `mbedtls_x509_buf`.
