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
