NAME¶
asn1_bit_der - API function
SYNOPSIS¶
#include <libtasn1.h>
void asn1_bit_der(const 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().
