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().
