Asn1_module

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.

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.
