"Beware of any vendor who claims to have invented a 'new type of cryptography' or a 'revolutionary breakthrough.' True breakthroughs are likely to show up in research literature, and professionals in the field typically won't trust them until after years of analysis, when they're not so new anymore.
"The strength of any encryption scheme is only proven by the test of time. New crypto is like new pharmaceuticals, not new cars. And in some ways it's worse: if a pharmaceutical company produces bogus drugs, people will start getting sick, but if you're using bogus crypto, you probably won't have any indication that your secrets aren't as secret as you think."
