The SHA-256 will match the shown for each gem published to RubyGems.org.
```console
# as a rake task:
bundle exec rake build:generate_checksums
# as a binstub:

## ✨ Installation
Install the gem and add to the application's Gemfile by executing:
$ bundle add stone_checksums
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install stone_checksums
### 🔒 Secure Installation
For Medium or High Security Installations
This gem is cryptographically signed, and has verifiable [SHA-256 and SHA-512][💎SHA_checksums] checksums by
[stone_checksums][💎stone_checksums]. Be sure the gem you install hasn’t been tampered with
by following the instructions below.
Add my public key (if you haven’t already, expires 2045-04-29) as a trusted certificate:
```console
gem cert --add <(curl -Ls https://raw.github.com/galtzo-floss/certs/main/pboling.pem)
```
You only need to do that once. Then proceed to install with:
```console
gem install stone_checksums -P HighSecurity
```
The `HighSecurity` trust profile will verify signed gems, and not allow the installation of unsigned dependencies.
If you want to up your security game full-time:
```console
bundle config set --global trust-policy MediumSecurity
```
`MediumSecurity` instead of `HighSecurity` is necessary if not all the gems you use are signed.
NOTE: Be prepared to track down certs for signed gems and add them the same way you added mine.
## ⚙️ Configuration
Configuration env vars:
- GEM_CHECKSUMS_CHECKSUMS_DIR: Where to write checksum files (default: checksums)
- GEM_CHECKSUMS_PACKAGE_DIR: Where to look for built gems (default: pkg)
- GEM_CHECKSUMS_GIT_DRY_RUN: When true, run a dry-run commit and clean up temporary files
- GEM_CHECKSUMS_ASSUME_YES: When true and Bundler < 2.7.0, proceed without interactive prompt (still requires SOURCE_DATE_EPOCH)
## 🔧 Basic Usage
### Generate Gem Checksums (SHA-256 and SHA-512)
This library helps you generate checksums for your built gem and commit them.
- Bundler >= 2.7.0: No SOURCE_DATE_EPOCH needed. Bundler now uses a constant timestamp internally, making builds reproducible by default.
- Bundler < 2.7.0: You must set SOURCE_DATE_EPOCH before building the gem to get deterministic checksums, or upgrade Bundler.
- If you still want to proceed on old Bundler non-interactively, set GEM_CHECKSUMS_ASSUME_YES=true (SOURCE_DATE_EPOCH is still required).
Usage via Rake (recommended):
```console
bundle exec rake build
bundle exec rake build:generate_checksums
```
Usage via CLI (equivalent):
```console
bin/gem_checksums [pkg/your_gem-1.2.3.gem]
```
### Public API (YARD)
- Module StoneChecksums (primary namespace)
- ::install_tasks() -> void — loads Rake tasks (delegates to GemChecksums.install_tasks)
- ::generate(git_dry_run: Boolean = false) -> void — generate SHA-256/512 checksums and commit (delegates to GemChecksums.generate)
- Error < GemChecksums::Error — error class hierarchy is preserved
- Version::VERSION: String — current gem version
- Module GemChecksums (deprecated, backward-compatible namespace)
- ::install_tasks() -> void — identical behavior
- ::generate(git_dry_run: Boolean = false) -> void — identical behavior
- Error — base error class used internally
- Version::VERSION: String — same as StoneChecksums::Version::VERSION
See the generated YARD docs for full details: [Current release on RubyDoc.info][🚎yard-current].
## 🦷 FLOSS Funding
While galtzo-floss tools are free software and will always be, the project would benefit immensely from some funding.
Raising a monthly budget of... "dollars" would make the project more sustainable.
We welcome both individual and corporate sponsors! We also offer a
wide array of funding channels to account for your preferences
(although currently [Open Collective][🖇osc] is our preferred funding platform).
**If you're working in a company that's making significant use of galtzo-floss tools we'd
appreciate it if you suggest to your company to become a galtzo-floss sponsor.**
You can support the development of galtzo-floss tools via
[GitHub Sponsors][🖇sponsor],
[Liberapay][⛳liberapay],
[PayPal][🖇paypal],
[Open Collective][🖇osc]
and [Tidelift][🏙️entsup-tidelift].
| 📍 NOTE |
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| If doing a sponsorship in the form of donation is problematic for your company
from an accounting standpoint, we'd recommend the use of Tidelift,
where you can get a support-like subscription instead. |

### Another way to support open-source
> How wonderful it is that nobody need wait a single moment before starting to improve the world.
>—Anne Frank
I’m driven by a passion to foster a thriving open-source community – a space where people can tackle complex problems, no matter how small. Revitalizing libraries that have fallen into disrepair, and building new libraries focused on solving real-world challenges, are my passions — totaling 79 hours of FLOSS coding over just the past seven days, a pretty regular week for me. I was recently affected by layoffs, and the tech jobs market is unwelcoming. I’m reaching out here because your support would significantly aid my efforts to provide for my family, and my farm (11 🐔 chickens, 2 🐶 dogs, 3 🐰 rabbits, 8 🐈 cats).
If you work at a company that uses my work, please encourage them to support me as a corporate sponsor. My work on gems you use might show up in `bundle fund`.
I’m developing a new library, [floss_funding][🖇floss-funding-gem], designed to empower open-source developers like myself to get paid for the work we do, in a sustainable way. Please give it a look.

⭐️ Star History
## 📌 Versioning
This Library adheres to [![Semantic Versioning 2.0.0][📌semver-img]][📌semver].
Violations of this scheme should be reported as bugs.
Specifically, if a minor or patch version is released that breaks backward compatibility,
a new version should be immediately released that restores compatibility.
Breaking changes to the public API will only be introduced with new major versions.
> dropping support for a platform is both obviously and objectively a breaking change
>—Jordan Harband ([@ljharb](https://github.com/ljharb), maintainer of SemVer) [in SemVer issue 716][📌semver-breaking]
I understand that policy doesn't work universally ("exceptions to every rule!"),
but it is the policy here.
As such, in many cases it is good to specify a dependency on this library using
the [Pessimistic Version Constraint][📌pvc] with two digits of precision.
For example:
```ruby
spec.add_dependency("stone_checksums", "~> 1.0")
```
📌 Is "Platform Support" part of the public API? More details inside.
SemVer should, IMO, but doesn't explicitly, say that dropping support for specific Platforms
is a *breaking change* to an API.
It is obvious to many, but not all, and since the spec is silent, the bike shedding is endless.
To get a better understanding of how SemVer is intended to work over a project's lifetime,
read this article from the creator of SemVer:

## 🤑 A request for help
Maintainers have teeth, and need to pay their dentists.
After getting laid off in an RIF in March, and filled with many dozens of rejections,
I'm now spending ~80 hours a week building open source tools.
I'm hoping to be able to pay for my kids' health insurance this month,
so if you value the work I am doing, I need your support.
Please consider sponsoring me or the project.
