NAME¶

asn1_encode_simple_der - API function

SYNOPSIS¶

#include <libtasn1.h>

int asn1_encode_simple_der(unsigned int etype, const unsigned char * str, unsigned int str_len, unsigned char * tl, unsigned int * tl_len);

ARGUMENTS¶

unsigned int etype

The type of the string to be encoded (ASN1_ETYPE_)

const unsigned char * str

the string data.

unsigned int str_len

the string length

unsigned char * tl

the encoded tag and length

unsigned int * tl_len

the bytes of the tl field

DESCRIPTION¶

Creates the DER encoding for various simple ASN.1 types like strings etc. It stores the tag and length in tl , which should have space for at least ASN1_MAX_TL_SIZE bytes. Initially tl_len should contain the size of tl .
