What did you do?

I want to write code that can efficiently encrypt or decrypt a portion of large files using random access I/O.
Theoretically in CTR mode it is possible to encrypt/decrypt arbitrary block independently.
But with the lack of alternative interface to Stream interface, there is no way to take advantage of CTR mode.

What did you expect to see?

Another interface for CTR mode, or maybe custom counter support would be good too.

What did you see instead?

Only Stream interface exists.
