Not really. It still returns a size one byte larger than expected for the
strings. Even in languages where NUL-terminated strings are the norm, the
terminating byte is not included in the length.
The point is, we expect this API to return exactly the data that was in the
certificate. If the caller wants to treat the data as a string, they can
NUL-terminate it themselves. The manpage only says that the data will be
returned, it does not say that it will be altered in any way.
Actually you are right. The return value shouldn't be increased (this also
happens in the other similar functions). I've corrected the patch and
