\usage{
cert_verify(cert, root = ca_bundle())
download_ssl_cert(host = "localhost", port = 443, ipv4_only = FALSE)
ca_bundle()
}
\arguments{
\item{cert}{certificate (or certificate-chain) to be verified. Must be cert or list or path.}
\item{root}{trusted pubkey or certificate(s) e.g. CA bundle.}
\item{host}{string: hostname of the server to connect to}
\item{port}{string or integer: port or protocol to use, e.g: \code{443} or \code{"https"}}
\item{ipv4_only}{do not use IPv6 connections}

\details{
If https verification fails and you can't figure out why, have a look
at \url{https://ssldecoder.org}.
}
\examples{
# Verify the r-project HTTPS cert
chain <- download_ssl_cert("cloud.r-project.org", 443)
print(chain)
cert_data <- as.list(chain[[1]])
print(cert_data$pubkey)
print(cert_data$alt_names)
cert_verify(chain, ca_bundle())
# Write cert in PEM format
cat(write_pem(chain[[1]]))
