NAME

6       asn1_octet_der - API function
7

SYNOPSIS

9       #include <libtasn1.h>
10
11       void  asn1_octet_der(const  unsigned  char * str, int str_len, unsigned
12       char * der, int * der_len);
13

ARGUMENTS

15       const unsigned char * str
16                   the input data.
17
18       int str_len STR length (str[0]..str[*str_len-1]).
19
20       unsigned char * der
21                   encoded string returned.
22
23       int * der_len
24                   number of meaningful bytes of DER (der[0]..der[der_len-1]).
25

DESCRIPTION

27       Creates a length-value DER encoding for the input data.  The DER encod‐
28       ing of the input data will be placed in the  der variable.
29
30       Note that the OCTET 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  en‐
34       coding. The DER encoding size can be obtained using asn1_length_der().
