They can't. There is exclusivity between these two. htML (markup language) is not the same thing as encryption. MAYBE thru SSL, or TLS, IPSEC?, or whatever ... and maybe through some kind of key infrastructure. The markup itself is insecure; some kind of encapsulation is required beyond HTML (any version that is open, 5 or not) to make it "secure".
