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().
