comment Should magnetic locks automatically release in the event of a fire alarm?
The specific type pictured is an electromagnetic lock, which is inherently fail safe. Electric strikes can be either fail safe or fail secure. Here's a good description of when each type is used: idighardware.com/wordpress/wp-content/uploads/2012/05/…

comment Should magnetic locks automatically release in the event of a fire alarm?
This is indeed a complex topic. The general requirement is to provide free egress, with very limited exceptions. This does not mean that the door cannot fail secure, it means that the door has to be openable from the inside when power has failed.

comment What is SHA-3 and why did we change it?
SHA-3, like SHA-2, is not intended for use as a password hash function.

comment How to verify that someone is who they say they are online?
Why is there a need to verify at application time? Usually, this sort of detailed verification is done later in the interview/hiring process. Also, keep in mind that using some forms of verification this early in the process may run afoul of employment discrimination laws; of course this depends on your location, but it is something else to keep in mind.

revised Can I expect my e-mail to be routed securely?
clarify that SSL does nothing to protect you from a compromised/malicious SMTP server
