NAME

6       asn1_bit_der - API function
7

SYNOPSIS

9       #include <libtasn1.h>
10
11       void asn1_bit_der(const unsigned char * str, int bit_len, unsigned char
12       * der, int * der_len);
13

ARGUMENTS

15       const unsigned char * str
16                   BIT string.
17
18       int bit_len number of meaningful bits in STR.
19
20       unsigned char * der
21                   string returned.
22
23       int * der_len
24                   number of meaningful bytes of DER (der[0]..der[ans_len-1]).
25

DESCRIPTION

27       Creates a length-value DER encoding for the input data as it would have
28       been for a BIT STRING.  The DER encoded data will be copied in  der .
29
30       Note that the BIT STRING tag is not included in the output.
31
32       This  function  does  not  return any value because it is expected that
33       der_len will contain enough bytes to store  the  string  plus  the  DER
34       encoding.    The    DER   encoding   size   can   be   obtained   using
35       asn1_length_der().
