Mas sobre la detección de datos criptograficos

He preguntado en Kriptopolis, a ver si me responde alguien.
Ya me han respondido en scr.crypt. Me indican, que en ddj salio algo hace poco.

There was a related article in the last few months in Dr. Dobb's Journal, but I

don't have that issue right at hand...



Basically, encrypted data looks random, so testing a block for randomness will

help to find ciphertext, but it will also find compressed blocks of data which

also look random.

Habrá que buscar en ddj a ver si veo algo...
