Encryption
The SHOUT sp can send and receive data in AES 256-bit encrypted format. The
Encryption settings menu provides a user interface to setup a crypto officer
password, change the crypto keys, and enable/disable encryption.
First time setup of the Crypto Officer password must be done before any encryption
properties can be configured. To setup the Crypto Officer password, Press
Encryption under the Security Settings menu. The user will be prompted to enter
the New Password and to confirm the password entry as seen in Figure 56. When
the new password is confirmed, press the OK button to allow entry of the Encryption
Key. Subsequent entry into the Security Settings Menu will require entry of the
Crypto Officer Password.
The Encryption Key must be set in order to use encryption. The Decryption Key is
optional but is required to receive encrypted data. After an encryption key has been
set, the Use Encryption option may be enabled.
