blsSecretKeyGetHexStr VS blsSecretKeySerialize results in different hex values

[paceto256]

I am trying to dump the hex prepresentation of the secret key. I am getting different hex using both methods, anyone have an idea which one is correct?

void dumpSec(blsSecretKey *sec)
{
    char buf[1024];
    size_t n = blsSecretKeyGetHexStr(buf, sizeof(buf), sec);
        printf("%s", buf);
}

void dumpSec2(blsSecretKey *sec)
{
    unsigned char buf[1024];
    size_t n = blsSecretKeySerialize(buf, sizeof(buf), sec);
    for (size_t i = 0; i < n; i++) {
        printf("%02x", buf[i]);
    }
}

void main() 
{
  blsSecretKey sec;
  blsPublicKey pub;

  dumpSec(&sec);
  printf("\n");
  dumpSec2(&sec);
}

Check your endianness. Those are the same values but read left-to-right/right-to-left.
