[Bacula-devel] Bacula hmac and bin_to_base64 question

[Derek W. <der...@gm...>]

Hello all, I'm attempting to write a very small program that utilizes the
bacula hmac and bin_to_base64 functions so I can auth to my director as a
console. It seems that my output is slightly different than what the
director computes for a base64 hash, example:

Director expects: p6+IvREdwWdjZ8kPkQ+cUC
But the program I wrote gives: p6+IvREdwWdjZ8kPkQ+cU

Where does this last letter come from and how come its missing off the end
of my base64 hash. Here is my program code:

#include "bacula.h"

char* chal;
char* password;
uint8_t hmac[20];
char base64[23];
uint8_t i;

int main(int argc, char *argv[])
{
        chal = argv[1];
        password = argv[2];
        hmac_md5((uint8_t *)chal, 50, (uint8_t *)password, strlen(password),
hmac);
        bin_to_base64(base64, sizeof(base64), (char *)hmac, 16, false) + 1;
        printf("%s\n", base64);
}
