TODO: Rename reuse-buffer to ad-hoc-buffer: We can"t update crypter in-place, need a seperate buffer :/

`reuse-buffer` feature available if explicitly opting into it. Buffers can be moved from internal<->external buffers. By default, internal buffers are used when `reuse-buffer` is disabled, and external ones are used when it is enabled.
