JOHN E. HOLT enscribed thusly:
The Pouch uses a 64 x 64 block product cipher, a 1024 bit random initialization vector and the CBC technique. Most experts agree that such an implementation is highly resistant to all forms of cryptographic attack. Hellman and Dilfie rely on knowing the algorithm for their known plain text attacks An unpublished algorithm forces them into reverse engineering the computer programs to learn the algorithm. The POUCH has many roadblocks built in to prevent this.
An unpublished algorithm mean that it's worthless snakeoil that depends on obfuscation until it is successfully reverse engineered (which you just set yourself up as a prime target) and then all of your chumps (ahh.. clients) get raped. I wouldn't even look at it and would advise all of my clients to avoid it like the plague...
I refer to Cummings, Cryptography and Data Security pages 150 and 98 in this regard. John Holt
