asn1_bit_der(3) libtasn1 asn1_bit_der(3)
NAME
asn1_bit_der - API function
SYNOPSIS
#include <libtasn1.h>
asn1_bit_der(3) 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().
