mbedtls_asn1_buf struct

Type-length-value structure that allows for ASN1 using DER.

Syntax

typedef struct mbedtls_asn1_buf {     int tag;                     size_t len;                  unsigned char *p;        } mbedtls_asn1_buf;

Fields

tag

ASN1 type, e.g. MBEDTLS_ASN1_UTF8_STRING. Read more...

len

ASN1 length, in octets. Read more...

p

ASN1 data, e.g. in ASCII. Read more...
