Implementing is easy (stolen from the docs):

MakeMaker:

    WriteMakefile(
        (MM->can('signature_target') ? (SIGN => 1) : ()),
        # ... original arguments ...
    );

Module::Build:

   Module::Build->new(
        (sign => 1),
        # ... original arguments ...
    )->create_build_script;

Don’t forget to add

to your

if needed.

Then when running

you will be prompted for the pass phrase for your gpg key. For extra goodness, add 0-signature.t to your tests. It includes a single test that verifies the package cryptographically during

if the

environment variable is set.

If you know waltman and haven’t heard of this module, yell at him for not telling you about it, he’s mentioned in the

file for his stellar documentation patches.
