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 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.
