	BufferBinarySource (std::shared_ptr< const SecureBytes > buffer, std::size_t offset, std::size_t size)
std::size_t	size () const noexcept override
	Returns the payload size in bytes.
void	Read (std::size_t offset, void *dst, std::size_t size) const override
	Copies size bytes starting at offset into dst.
void	WriteTo (std::ostream &dst) const override
	Writes the whole payload to dst without materializing a copy.
