There is often a need to generate test certificates automatically using

a script. This is often a cause for confusion which can result in incorrect

CA certificates, obsolete V1 certificates or duplicate serial numbers.

The range of command line options can be daunting for a beginner.

The mkcerts.sh script is an example of how to generate certificates

automatically using scripts. Example creates a root CA, an intermediate CA

signed by the root and several certificates signed by the intermediate CA.

The script then creates an empty index.txt file and adds entries for the

certificates and generates a CRL. Then one certificate is revoked and a

second CRL generated.

The script ocsprun.sh runs the test responder on port 8888 covering the

client certificates.

The script ocspquery.sh queries the status of the certificates using the

test responder.
