asn1_bit_der - API function
#include <libtasn1.h> void asn1_bit_der(const unsigned char * str, int bit_len, unsigned char * der, int * der_len);
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..der[ans_len-1]).
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().
