NAME

asn1_octet_der - API function

SYNOPSIS

#include <libtasn1.h>

void asn1_octet_der(const unsigned char * str, int str_len, unsigned char * der, int * der_len);

ARGUMENTS

const unsigned char * str

the input data.

int str_len

STR length (str[0]..str[*str_len-1]).

unsigned char * der

encoded string returned.

int * der_len

number of meaningful bytes of DER (der[0]..der[der_len-1]).

DESCRIPTION

Creates a length-value DER encoding for the input data. The DER encoding of the input data will be placed in the der variable.

Note that the OCTET 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().
