SSL/TLS

Configure the following parameters:

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

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.

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

Click this button to create peer certificate validation criteria that must be met 

for a valid SSL/TLS connection.

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.
