Simply put, encryption is the translation of data into a secret code to protect it from being stolen.
To use any of the encryption functions, the IS 2225/30 must be equipped with the printer/scanner

Communication Path Protection by SSL (Secure Socket Layer)
SSL Encryption is the protocol that creates a secure connection between the client PC and the
server. This is the protocol that is used for online credit card transactions. SSL Encryption
ensures that data is protected from interception, tampering with or analysis.
When accessing the machine using a Web browser, IPP, or SmartDeviceMonitor for Admin,
customers establish encrypted communication as described in the following flowchart.
1. When accessing the machine from a user’s PC, the user’s PC requests the SSL server
certificate and public key from the machine
2. The server certificate and public key are sent from the machine to the user’s PC. There are
2 types of server certificate: self-signed, or one that is issued by a certificate authority
3. By using the public key, the data is encrypted and ready for transmission
4. The encrypted data is sent to the machine
5. The encrypted data is decrypted using the private key
