Protocols like HTTP, FTP(S), LLP, and SMTP may use TLS to encrypt communication. When using the various Network Client APIs in the Translator, TLS can be used.

...

verify_peer - Ensures that the server's certificate is valid and trusted by verifying it against a Certificate Authority (CA).
verify_host - Ensures that the server's certificate is specifically intended for the hostname you are connecting to.
ca_file - Optional, use if you need to specify the path to a custom CA File for peer verification.
cert - For mTLS, the client is required to provide a certificate to be verified by the server.
key - For mTLS, the client is required to use a private key to provide a signature proving that the client has the private key associated with the public certificate it presents.

Specific Configuration:

The Translator’s Network Client APIs have slightly different configuration parameters, choose the dropdown below to view the specific configurations and an example with each client API:

title	HTTPS - net.http

By HTTP uses one-way TLS by default, the net.http.* client APIs are set to verify as the verify_peer and verify host, therefore one way TLS is supported_host parameters are set to true.

To enable use two-way mTLS, you can provide an ssl parameter can be passed as a table of values to the net.http.* client APIs.:

Code Block

language	lua

-- add parameters to ssl table 
local ssl_info = {
   cert= iguana.workingDir()..'configurations/web/cert.pem',
   key= iguana.workingDir()..'configurations/web/key.pem'
}
 
-- pass ssl_info to the net.http ssl parameter    
local r, c, h = net.http.post{
   url='httphttps://localhost:6544/demo', 
   body=Data,
   ssl=ssl_info,
   live=true
}

Below is the full list of available ssl table parameters. See the built-in help documentation in the Translator for additional details:

FTP use uses one-way TSLTLS by default.

The

, as the use_ssl parameter is set to 'try' (meaning optional)

as default

, along with the verify_peer and verify_host parameters set to true.

To use two-way mTLS, you can provide the following ssl related parameters:

      live=true
}

Below is the full list of available ssl related parameters. See the built-in help documentation in the Translator for additional details:

private_key_file	The name of your private key file.
private_key_pass	The password to access your private key.
private_key_type	Your private key's type: PEM, DER, or ENG.	`PEM`

title	FTPS - net.ftps.init

FTPS uses one-way TLS by default, as the force_ssl, verify_peer and verify_host parameters are set to true.

To use two-way mTLS, you can provide the following ssl related parameters:

Code Block

language	lua

local r, c, h = net.ftps.init

used to initialize the connection. By default, the force_ssl parameter is true to use TLS.
