Size of buffer is not big enough to accomodate endpoints with long host names. #45

When the length of endpoint hostname exceeds 40bytes, hostname to be used to sign authentication header gets truncated, this will cause SignatureDoesNotMatch error.

Would it be possible to expand the size of the buffer to safe size?
