Certificate File Requirements
PEM (Privacy‑enhanced Electronic Mail) file types are ASCII encoded, and they are the required
format for 802.1X authentication for the TouchLink Pro control systems. DER (Distinguished
Encoding Rules) file types are binary encoded and can typically have several file extension
variations, such as .crt and .cer.
NOTE:
DER encoded files (files with .der, .crt, or .cer extensions that are encoded in DER
binary format) must be converted to a PEM encoded file type (.pem) before being used for
authentication.
DER encoded certificates must be converted to PEM encoding using a third‑party tool. Contact
your IT administrator for more information on required tools.
To create the 802.1X security certificate for uploading to Extron TouchLink Pro control systems,
ensure that the certificate file meets the following requirements:
•
It contains X.509 certificate information.
•
It contains a private key (for machine certificates only).
•
It is PEM encoded.
•
It has a file extension that is .crt or .pem
•
Its file name consists of the following types of valid characters:
•
Alphanumerical (A‑Z, a‑z, 0‑9) characters
•
Some special characters (colon [:], underscore [_], and hyphen [‑])
NOTE:
Spaces are not permitted anywhere in the name.
Private Key File Requirements
Private key files are required only when employing machine certificates. Follow these
requirements for creating a private key:
•
Its file name consists of the following types of valid characters:
•
Alphanumerical (A‑Z, a‑z, 0‑9) characters
•
Some special characters (colon [:], underscore [_], and hyphen [‑])
•
It has a file extension that is .key or .pem.
•
It can have optional encryption (via password or passphrase).
