Secure Sockets Layer (SSL) Certificates
Extron controllers 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 controller.
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.
IP Link Pro controllers support standard OpenSSL certificate encodings such as .pem
(Privacy-enhanced Electronic Mail) and .der file types. PEM file types are ASCII encoded
and are the required format for uploading to the controller. DER (Distinguished Encoding
Rules) 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
controller.
To properly create the certificate for uploading to Extron controllers, 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.
