Create a TLS configuration object to be used for secure connections. Specify
client to create a client configuration or server to create a server
configuration.
tls_config(client = NULL, server = NULL, pass = NULL, auth = is.null(server))A 'tlsConfig' object.
either the character path to a file containing X.509
certificate(s) in PEM format, comprising the certificate authority
certificate chain (and revocation list if present), used to validate
certificates presented by peers,
or a length 2 character vector comprising [i] the certificate
authority certificate chain and [ii] the certificate revocation list, or
empty string "" if not applicable.
either the character path to a file containing the
PEM-encoded TLS certificate and associated private key (may contain
additional certificates leading to a validation chain, with the leaf
certificate first),
or a length 2 character vector comprising [i] the TLS certificate
(optionally certificate chain) and [ii] the associated private key.
(optional) required only if the secret key supplied to server
is encrypted with a password. For security, consider providing through a
function that returns this value, rather than directly.
logical value whether to require authentication - by default TRUE
for client and FALSE for server configurations. If TRUE, the session is
only allowed to proceed if the peer has presented a certificate and it has
been validated. If FALSE, authentication is optional, whereby a certificate
is validated if presented by the peer, but the session allowed to proceed
otherwise. If neither client nor server are supplied, then no
authentication is performed and this argument has no effect.
Specify one of client or server only, or neither (in which case an empty
client configuration is created), as a configuration can only be of one type.
For creating client configurations for public internet usage, root CA
ceritficates may usually be found at /etc/ssl/certs/ca-certificates.crt
on Linux systems. Otherwise, root CA certificates in PEM format are available
at the Common CA Database site run by Mozilla:
https://www.ccadb.org/resources (select the Server Authentication
SSL/TLS certificates text file).
