Schneier once believed that these signatures could be made tamperproof, but now argues that this is unworkable.

His change of heart is astonishing because, as the author of Applied Cryptography, the standard text book on the making and breaking of security codes, he is considered to be a key figure in the development of the technology. Schneier thinks some weak links in internet security may never be overcome.

One of his concerns is the protection of passwords from prying eyes. Most people use common passwords, such as the name of their spouse or favourite football team. …
