They provide several examples of cyphertext (and the plaintext) and invite the public to break the algorithm using that, as a demonstration of their confidence that it's unbreakable.
#One time pad system cracked
That also strongly implies that, since they don't know algorithms or structure, they're not only bad at math but also not very good at programming, so the implementation has a much higher chance of being cracked without even bothering to crack their incompetent algorithm.
"E2Sec is not structured and uses no algorithms, therefore unbreakable" That doesn't mean that it doesn't have a mathematical structure - it only means that they're not mathematicians, don't understand the structures, and aren't very good at algorithms, therefore it should be easily breakable.
This product has pretty much all the signs of the classic snake oil psuedo-one-time-pad, except that if you can believe their white paper, it's weaker than most snake oil products.
