usage_description="
Creates a Jenkins Certificate Credential in the given credential store and domain

Defaults to the 'system::system::jenkins' provider store and global domain '_'

If credential id and PKCS#12 keystore file aren't given as arguments, then reads from stdin, reading in
'ID=/path/to/keystore Description' or standard shell export format - useful for shell piping

In cases where you are reading secrets from stdin, you can set the store and domain via the environment variables
\$JENKINS_SECRET_STORE and \$JENKINS_SECRET_DOMAIN

Tested on Jenkins 2.319 with Credentials plugin 2.5

Uses the adjacent jenkins_cli.sh - see there for authentication details


Examples:

    # If you want to create a sample p12 file, you can do it like this:

        openssl req -x509 -nodes -newkey rsa:2048 -keyout test.key -out test.crt -subj '/CN=test.com'
        openssl pkcs12 -export -inkey test.key -in test.crt -passout pass: -out test.p12

    # create a credential with id 'aws-access-key-csv', and file ~/.aws/keys/jenkins_accessKeys.csv:

        ${0##*/} my-certificate-keystore ~/Downloads/test.p12

    # with a description, leaving the store and domain as the default global one:

        ${0##*/} my-certificate-keystore ~/Downloads/test.p12 '' '' 'My Certificate Keystore'

    # or piped from standard input:

        # export KEYSTORE_PASSWORD, JENKINS_SECRET_STORE and JENKINS_SECRET_DOMAIN if using stdin but not using system global store

        echo my-certificate-keystore=~/Downloads/test.p12 | ${0##*/}
