TLS options for a Trino connection

Description

Collects the TLS settings applied to every request made on a connection. Pass the result as the ssl_options argument of dbConnect().

Usage

trino_ssl(verify = TRUE, ca_bundle = NULL)

Arguments

`verify`	Whether to verify the server's certificate. Defaults to `TRUE`.
`ca_bundle`	Path to a PEM file holding the certificate authorities to trust, or `NULL` to use the system store.

Details

A cluster whose certificate is signed by an internal authority does not need verification turned off: point ca_bundle at the authority's PEM file and certificates keep being checked. verify = FALSE accepts any certificate, including an attacker's, and so dbConnect() warns once when it opens a connection with it.

Value

A list of TLS options.

Examples

# Secure default
trino_ssl()

# Trust an internal certificate authority
## Not run: 
trino_ssl(ca_bundle = "/etc/ssl/certs/internal-ca.pem")

## End(Not run)
