Fixes #181

[As we are patching 1.2 to fix some minor issues, it is worth including this clarification before 1.3.]

You have lost the sentence

A counter block value must only be used once across all messages encrypted using the same key value.

This is the key cryptographic property, so should be retained.

I've added a patch to reinstate it (or an equivalent). Please check the result conveys the intended meaning effectively.

Yes, that looks OK. Thanks.
