write_cert: Generate Self-Signed Certificate and Key
| write_cert | R Documentation |
Generate Self-Signed Certificate and Key
Description
Generate self-signed x509 certificate and 4096 bit RSA private/public key pair for use with authenticated, encrypted TLS communications.
Usage
write_cert(cn = "127.0.0.1", valid = "20301231235959")
Arguments
cn |
[default '127.0.0.1'] character issuer common name (CN) for the certificate. This can be either a hostname or an IP address, but must match the actual server URL as client authentication will depend on it. |
valid |
[default '20301231235959'] character 'not after' date-time in 'yyyymmddhhmmss' format. The certificate is not valid after this time. |
Details
Note that it can take a second or two for the key and certificate to be generated.
Value
A list of length 2, comprising $server and $client. These may be
passed directly to the relevant argument of tls_config().
Examples
cert <- write_cert(cn = "127.0.0.1")
ser <- tls_config(server = cert$server)
cli <- tls_config(client = cert$client)
s <- socket(listen = "tls+tcp://127.0.0.1:5555", tls = ser)
s1 <- socket(dial = "tls+tcp://127.0.0.1:5555", tls = cli)
# secure TLS connection established
close(s1)
close(s)
cert
