Please explain how you propose to determine the difference between encryption and obfuscation using PSK. Please explain the relivance at all of the write blocker comment. This is not a forensic capture - it is testing encrpytion. It is an internal job and unrelated to any forensic exercise. Explain if you will how you intend to determine if I have for instance used strong crypto and not a home made 4 bit DES variant using the tools that come with PSK to determine this. Statistical methods will (at times) AID in the determination of crypto (and very occasionally an indictation of type) by looking at the distribution of noise etc. I see no tools for this on PSK.

Translation - Gain confidence by buy something good that's been independently tested ideally used by government bodies, and be sure to use it in the manner the vendor suggests. And get your boss to sign-off that he/she's happy with this proxy approach.
