WebCTR is counter-mode. The gist is that: You encrypt a counter stream. A counter stream is just the stream of values you get from a counter. For example, 1, 2, 3, 4, etc.. Assuming that your encryption method was secure, then your counter stream should be pseudo-random to anyone who doesn't know how you encrypted it.
