> We assume that the binary expansion of Pi is not selected maliciously. ;-)

Well, I suppose that we must assume that, as assuming otherwise is self-defeating: anyone running the simulation we're living in already has direct access to the plaintexts anyway.




That somebody maliciously caused the circle's circumference to diameter ratio to be insecure in this application is indeed not an issue.

However, a possible danger is that somebody maliciously suggested using π instead of e...


True, but Pi is pretty much tradition now... enough so that when Decorrelated Fast Cipher used e instead, it raised some eyebrows.
