As with all potential snake oil, there aren't any specs available. In fact,
it is frequently the lack of publicly available specs that makes a crypto
system a candidate for snake oil. Whenever I hear "trust us, the system is
secure" an alarm bell goes off in my head. Discovering what ciphers are
used in systems that use non-public designs is the hard part. The
cryptanalysis tends to be the easy part.
The recent GSM break is a good example: it took some 8 years before the
cipher used was discovered. The cryptanalysis required all of two hours.
