Looks like it's just adding convenience to built-in RubyGems signing. Relevant lines: https://github.com/steakknife/waxseal/blob/master/bin/waxseal#L59 https://github.com/steakknife/waxseal/blob/master/bin/waxsea... (generates the signature using "gem cert --build ...") https://github.com/steakknife/waxseal/blob/master/bin/waxseal#L83 https://github.com/steakknife/waxseal/blob/master/bin/waxsea... (modifies your gemspec file to include the signing key and cert)
