Secure Sockets Layer (SSL) Certificates
Extron NAV devices ship with factory-installed SSL certificates created by Extron. If you
want or are required to use a different SSL certificate at your installation site, then you can
use system utilities in the Toolbelt software to change the SSL certificate at any time. The
Toolbelt Help File provides instructions on how to apply an SSL certificate to a device.
NOTES:
•
You must run Toolbelt as an administrator.
•
Some certificates require a passphrase that is created when the certificate is
created. If a passphrase is required, you must enter that passphrase before
uploading and applying the certificate.
NAV devices support standard OpenSSL certificate encodings such as .pem (Privacy-
enhanced Electronic Mail) and .der (Distinguished Encoding Rules) file types. PEM file types
are ASCII encoded and are the required format for uploading to the device. DER file types
are binary encoded and can typically have several file extension variations, such as .crt and
.cer. There are many standard tools that can convert from DER to PEM file encodings if
needed.
NOTE: A DER format file must be converted to PEM encoding before uploading it to the
device.
To properly create the certificate for uploading to Extron NAV devices, ensure that the
certificate file meets the following requirements:
Contains X.509 certificate information
•
•
Contains public and private keys
•
Uses PEM encoding
NOTE: ITU-T standard X.509 covers aspects of public key encryption, digital
cryptography, certificates, and validation.
Contact your IT administrator for more information on what tools and policies are required to
obtain or create the SSL certificate and, if necessary, the corresponding passphrase.
