Lines: 12 - It is virtually impossible for an outsider to break the - decrypting key, which consists of a binary string of more than 1,000 - characters, Mr. Vanstone said. - "It would take more than a billion years, working with the - fastest computers available, to break just one key," he said. I hope it is obvious to most readers of this newsgroup that the above claim is bullshit. A similar argument would lead to the claim that Rubik's cube would take forever to solve. I personally have broken cryptosystems with longer keys. There is more to cryptosystem strength than key length.
