Montagu Certificate Tool

This is a Kotlin application for performing various tasks relating to certificate management.

You can run it without cloning the repository like so:

docker run docker.montagu.dide.ic.ac.uk:5000/montagu-cert-tool:master

Generate self-signed certificate

To generate a self-signed certificate with OpenSSL run

mkdir workspace
docker run --rm \
    -v $PWD/workspace:/workspace \
    docker.montagu.dide.ic.ac.uk:5000/montagu-cert-tool:master \
    gen-self-signed /workspace

This will output two files, certificate.pem and ssl_key.pem, to the local workspace folder. Be careful with these unencrypted files - any spare copies should be deleted after they have been copied into the docker container that is running the webapp.

rm -r workspace

The -v command makes the workspace folder available to the cert-tool's container at /workspace.

Generate an RSA keypair

To generate an RSA keypair using OpenSSL run

mkdir workspace
docker run --rm \
    -v $PWD/workspace:/workspace \
    docker.montagu.dide.ic.ac.uk:5000/montagu-cert-tool:master \
    gen-keypair /workspace

This will output two files, private_key.der and public_key.der, to the local workspace folder. Be careful with the unencrypted privat key - any spare copies should be deleted. e.g.

rm -r workspace
