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

General TLS configurations:

One-way TLS - Only the client verifies the server’s certificate.
Two-way Mutual TLS (mTLS) - Both the client and the server authenticate each other’s certificates.

There are a few key parameters used to enable these TLS configurations:

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.

Translator Net API-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:

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

To use two-way mTLS, you can provide an ssl parameter can be passed as a table of values:

-- 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='https://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:

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:

      server='ftps://speedtest.tele2.net',
