The -Z CACertificateFile option is used to specify a file containing the CA certificates in PEM format which are required for TELNET server authentication. The individual PEM certificates are arranged sequentially in the file.
You can process the file with a text editor of your choice when you wish to add or delete certificates. The individual certificates are registered in the file as follows:
-----BEGIN CERTIFICATE----< CA certificate in Base64 encoding > -----END CERTIFICATE-----
Text outside these sequences is ignored by the TELNET client and can therefore be used to identify the certificates which, owing to the ASN.1/Base64 encoding, are not available in readable form.
