MonitorMagic Web Interface
yourself with a digital certificate. The use of someone elses public key is what allows you to
decrypt data that has been encrypted with their private key. As seen partly in the Configure
MonitorMagic WebService: Configure Certificate section, the following is the information that is
included in a digital certificate:
Owner's public key
Owner's name
Expiration date of the public key
Name of the issuer
Serial number of the digital certificate
Digital signature of the issuer
How does encrypted communication actually commence?
Without getting too complicated, encrypted communication begins with the exchange of public
keys. As stated before you need the senders public key to decrypt information sent with the
senders private key. Once keys have been exchanged the sender creates a message and passes
it through a special algorithm which creates a message, the message is then encrypted with the
private key. The sender then transmits the message to the recipient. Once the recipient receives
the message it passed through the same special algorithm to re-create the message. The
message is then decrypted using the senders public key. If the re-created message is the same
as the message originally created encrypted communication can truly commence.

Man in the middle attack
Although HTTPS (secure socket layer) is a very safe and secure form of encryption it is
susceptible to one type of interception known as the man in the middle attack. If you want to use
the MonitorMagic web interface over the Internet there is a way you can avoid being susceptible
to this type of attack. After MonitorMagic generates a digital certificate for you, save it to floppy
disk. If you want to use the MonitorMagic web interface from home bring the floppy disk
containing your digital certificate home with you. Install the digital certificate on your web browser
at home off the floppy disk. Your susceptibility to the man in the middle attack has now been
circumvented, the attack can only take place during the initial exchange of digital certificates and
keys.
