last week's discussion on encryption in a pen test got me thinking. do any of you know of any software that can evaluate a block of data and make a decent guess as it if the data is potentially encrypted data, and if so with what algorithms? when compared to purely random bits, that is. i understand that it should be possible for some algorithms, which produce bit frequencies that deviate noticably from random data. i have looked in some usual places (including zedz), and either i missed it or it doesn't exist. thanks. basically we're evaluating a mountain of data and want to see if some of it is encrypted or not (as opposed to random data produced by our extraction methods). ____________________________ jose nazario jose () cwru edu PGP: 89 B0 81 DA 5B FD 7E 00 99 C3 B2 CD 48 A0 07 80 PGP key ID 0xFD37F4E5 (pgp.mit.edu)
