## ASN1 Error codes
These error codes are OR'ed to X509 error codes for higher error granularity. 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`.
