Detailed Description

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
	Out of data when parsing an ASN1 data structure. More...
#define	MBEDTLS_ERR_ASN1_UNEXPECTED_TAG   -0x0062
	ASN1 tag was of an unexpected value. More...
#define	MBEDTLS_ERR_ASN1_INVALID_LENGTH   -0x0064
	Error when trying to determine the length or invalid length. More...
#define	MBEDTLS_ERR_ASN1_LENGTH_MISMATCH   -0x0066
	Actual length differs from expected length. More...
#define	MBEDTLS_ERR_ASN1_INVALID_DATA   -0x0068
	Data is invalid. More...
#define	MBEDTLS_ERR_ASN1_ALLOC_FAILED   -0x006A
	Memory allocation failed. More...
#define	MBEDTLS_ERR_ASN1_BUF_TOO_SMALL   -0x006C
	Buffer too small when writing ASN.1 data structure. More...

DER constants
These constants comply with DER encoded the ANS1 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.
