cert |

root |
trusted pubkey or certificate(s) e.g. CA bundle. |

# Verify the r-project HTTPS cert
chain <- download_ssl_cert("www.r-project.org", 443)
print(chain)
print(as.list(chain[[1]])$pubkey)
cert_verify(chain, ca_bundle())
# Another example
chain <- download_ssl_cert("public.opencpu.org")
ocpu <- chain[[1]]
as.list(ocpu)$subject
# Write PEM format
write_pem(ocpu)
