There's very good evidence that Al Qaida does *not* use strong crypto.
However, they use some form of crypto. From a recent press release of our attorney general: | Als mitgliedschaftliche Betdtigung im Sinne der Strafvorschrift des ' | 129b StGB f|r die "Ansar al Islam" wird den Beschuldigten vor allem | zur Last gelegt, einen Mordanschlag auf den irakischen | Ministerprdsidenten wdhrend seines Staatsbesuches in Deutschland am | 2. und 3.

(Very rough translation: "The persons are accused of being members of "Ansar al Islam" and planning the assassination of the Iraqi prime minister during his visit to Germany on the 2nd and 3rd December, 2004. This follows from the contents of a multitude of encrypted telephone calls the accussed exchanged since November 28, 2004.") Probably, they just used code words, and no "real" cryptography. I'm trying to obtain a confirmation, though.
