asn1_bit_der - API function
void asn1_bit_der(const unsigned char * str, int bit_len, unsigned char
* der, int * der_len);
const unsigned char * str
int bit_len number of meaningful bits in STR.
unsigned char * der
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
