Yes, you should use the advanced format if you have problems with
binary files (did you remember to use the "b" modifier to fopen?).

static char *
make_advanced (gcry_sexp_t sexp)
{
  int rc;
  size_t len;
  unsigned char *result;

  len = gcry_sexp_sprint (sexp, GCRYSEXP_FMT_ADVANCED, NULL, 0);
  assert (len);
  result = xmalloc (len);
  len = gcry_sexp_sprint (sexp, GCRYSEXP_FMT_ADVANCED, result, len);
  assert (len);
  gcry_sexp_release (sexp);
  return result;
}

This returns a C String suitable for printing.  gcry_sexp_sscan()
automatically detects the S-expression format, so there is nothing
special you need to do when reading the file back.

Beware, 1.1.12 won't be maintained anymore - we changed the API with
1.1.42 and is is suggested to use this new version.



Shalom-Salam,
