SSL/TLS
Field Descriptions
Configure the following parameters:
SSL/TLS Version Specify whether you want to use:
z Any—The IOLAN will try a TLSv1 connection first. If that fails, it will
try an SSLv3 connection. If that fails, it will try an SSLv2 connection.
z TLSv1—The connection will use only TLSv1.
z SSLv3—The connection will use only SSLv3.
Default: Any
SSL/TLS Type Specify whether the IOLAN serial port will act as an SSL/TLS client or server.
Default: Client
Cipher Suite Button Click this button to specify SSL/TLS connection ciphers.
Validate Peer
Certificate Enable this option when you want the Validation Criteria to match the Peer
Certificate for authentication to pass. If you enable this option, you need to
download an SSL/TLS certificate authority (CA) list file to the IOLAN.
Default: Disabled
Validation Criteria
Button Click this button to create peer certificate validation criteria that must be met
for a valid SSL/TLS connection.
SSL Certificate
Passphrase This is the SSL/TLS passphrase used to generate an encrypted RSA/DSA
private key. This private key and passphrase are required for both HTTPS and
SSL/TLS connections, unless an unencrpyted private key was generated, then
the SSL passphrase is not required. Make sure that you download the SSL
private key and certificate if you are using the secure HTTP option (HTTPS) or
SSL/TLS. If both RSA and DSA private keys are downloaded to the IOLAN,
they need to be generated using the same SSL passphrase for both to work.
