NAME

asn1_bit_der - API function

SYNOPSIS

#include <libtasn1.h>

void asn1_bit_der(const unsigned char * str, int bit_len, unsigned char * der, int * der_len);

ARGUMENTS

const unsigned char * str: BIT string.
int bit_len: number of meaningful bits in STR.
unsigned char * der: string returned.
int * der_len: number of meaningful bytes of DER (der[0]..der[ans_len-1]).

DESCRIPTION

Creates a length-value DER encoding for the input data as it would have been for a BIT STRING. The DER encoded data will be copied in der .

Note that the BIT STRING tag is not included in the output.

This function does not return any value because it is expected that der_len will contain enough bytes to store the string plus the DER encoding. The DER encoding size can be obtained using asn1_length_der().
