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().
