Coersion Re: don't use passwords as private keys (was Re: Using a password as a private key.)

From information given by a security consultant teaching a course I attended :

The easiest way to get a password from someone is to ask them. Many people will tell you if you look official, friendly etc Torture is less likely to work as people don't like to have to do something. They are often willing to "volenteer" information as long as they still appear to be in control.
