Sigilet – Open Badges Issuer & Digital Certificates

Issue digital badges from the WordPress site you already run. Your recipients get a credential they can add to LinkedIn, download, and show an employer, and anyone can check it on your domain.

Sigilet suits training providers, membership associations, universities and employers who award certificates or recognition and need those awards to be verifiable. No badge platform sits in the middle, there is no fee per badge, and your recipients never create an account.

Badges follow Open Badges 2.0 (OB 2.0), so any conformant wallet or verifier can read them.

How it works

1. Create a badge type: a title, what it is awarded for, and an image.
2. Award it to an email address. Issue it now, email the recipient, or hold it as a draft until launch day.
3. The recipient gets a public verification page on your domain, a LinkedIn share button, and a download.

What you get

Badge types and a three-mode award workflow, hosted verification on your own domain, one-click revoke and un-revoke, optional expiry dates, Badge Issuer and Badge Viewer roles so you can let someone award badges without handing over the rest of WordPress, and a private sharing panel for each recipient. Downloaded badges carry their own proof inside the image file, so they work in any OB 2.0 wallet rather than being just a picture.

Sigilet never stores a recipient’s email address. Each award keeps a one-way hash instead, so two badges held by the same person cannot be linked from the public record.

Screenshots are below. The Sigilet for WordPress page carries the technical detail: the OB 2.0 JSON Sigilet publishes, how badge baking works, how the privacy hashing works, and the server requirements.

Pro

CSV bulk award, which imports a spreadsheet of recipients and sends the awards through a paced background email queue, is a separate Sigilet Pro package and is not part of this download. None of its code ships here. There is no locked screen, no disabled control and no trial, and everything described above is free and does not expire.

External services

The WordPress.org build sends no licensing, analytics or update request to anyone. It takes updates only from WordPress.org.

Sigilet Pro connects to the Sigilet licensing service at licence.sigilet.com to activate a licence, to check once a day that the licence is still current, and to fetch Pro updates. It sends the licence key, a one-way SHA-256 hash of this site’s address, the site URL when a licence is activated, and the plugin version when WordPress checks for updates. It sends no site diagnostics, no administrator details, no list of installed themes or plugins and no badge recipient data, at any time. The licence key and a signed entitlement token are stored in this site’s options table, and the token is checked on this site, so Pro keeps working through a service outage.

Pro checkout runs on Polar, the merchant of record, reached from Sigilet’s pricing page. The plugin does not embed Polar, receive payment details or call Polar’s API. Polar handles the customer account, payment, tax, invoice, refund and subscription data.

No badge recipient data reaches the licensing service, Polar or any other outside service. See Sigilet’s Privacy Policy and Polar’s Privacy Policy.

1. Upload the plugin to wp-content/plugins/, or install it from the Plugins screen, and activate Sigilet.
2. Go to Sigilet → Settings and fill in your organization name, URL, and contact email.
3. If verification URLs return 404, visit Settings → Permalinks and click Save Changes once to flush rewrite rules.

1.6.7

• Renamed so people looking for an Open Badges issuer can find it. The plugin is now listed as “Sigilet – Open Badges Issuer & Digital Certificates” instead of just “Sigilet”. No functional change: same code, same settings, same badges, and the same plugin folder, so nothing needs reconfiguring.

1.6.6

• The free plugin now shows where to buy Pro, and how to get back to a copy already paid for. A Sigilet Pro section on the Badges settings screen links to the pricing page and to your Sigilet account, and the Plugins list gains a Go Pro link on Sigilet’s own row. Both appear only when Pro is not active, and only on Sigilet’s own screens, so nothing is added to the WordPress dashboard at large. A license key does not upgrade the free plugin in place: Pro is a separate download, replacing the free copy.
• Pro only: WordPress can no longer be told the installed plugin is an older version than it is. When the licensing service’s newest release is behind the installed build (a pulled release, or a pre-release tree), the version recorded for the plugin is now floored at the installed one. No site running a current release is affected.

Earlier releases are listed in changelog.txt, bundled with the plugin.
