Decrypting Blackbox secrets at build time with Paperkey

“Security is 1% technology plus 99% following the procedures correctly” — Tom Limoncelli

Having dealt with GPG last week at work, I remembered that I had intended to write a blog post about how we used GPG, Blackbox, and Paperkey to store secrets in Git at my previous job.

We used Blackbox to manage secrets that were needed during de­vel­op­ment, build, deployment, and runtime. These secrets included AWS cre­den­tials, Docker registry cre­den­tials, our private PyPI cre­den­tials, database cre­den­tials, and cer­tifi­cates. We wanted these secrets to be under version control, but also to be secure.

For example, we had a cre­den­ that exported en­vi­ron­ment variables, which was managed by Blackbox:

Jenkins Pipelines

I just published a series of blog posts at the MetaBrite DevBlog about our ex­pe­ri­ences in migrating to Jenkins and Pipelines.

Computed Parallel Branches in Jenkins Pipeline

I've been using Jenkins lately, setting up Pipeline builds. I have mixed feelings about that, but I'm quite liking Groovy.

Here's an example of a Closure called ac­cep­tance_in­te­gra­tion_tests, where the re­lease_lev­el parameter is a String which must be either "dev" or "prod".

def acceptance_integration_tests = { String release_level ->
    assert release_level =~ /^(dev|prod)$/
    String arg = "--${release_level}"

    def branches = [
        "${release_level}_acceptance_tests": {
            run_tests("ci_acceptance_test", arg, '**/*nosetests.xml')
