#55: Add GPG_PRIVATE_KEY secret pass-through and remove committed GPG keys

[chetankh239]

Adds GPG_PRIVATE_KEY to the maven-build and maven-publish-to-nexus job secrets, and removes the leaked .github/keys/mosipgpgkey_*.gpg files from tracking (ignored going forward).

Ref: mosip/mosip-labs#55

Summary by CodeRabbit

• Chores
  • Automated builds and publishing now run for changes to the gpg-migration branch.
  • Build and publishing processes securely receive the required signing key.
  • Project ignore rules now preserve relevant settings files while excluding sensitive key files.
  • These updates improve release automation and help prevent accidental inclusion of protected credentials in project changes.

Walkthrough

This PR updates the push workflow for the gpg-migration branch, uses the gpgupdate-masterj21 Maven workflows, passes GPG_PRIVATE_KEY to build and publish jobs, and narrows one .gitignore rule.

Changes

Workflow and repository settings

Layer / File(s)	Summary
Workflow trigger and GPG secret wiring .github/workflows/push-trigger.yml	The workflow now triggers on gpg-migration, uses the gpgupdate-masterj21 build and Nexus publishing workflows, and passes GPG_PRIVATE_KEY to both jobs.
Scoped settings key ignore rule .gitignore	The ignore rule now targets only */.settings/.github/keys/ instead of all */.settings/ directories.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to b4263

This change passes a private GPG key into reusable workflows referenced by a mutable ref, so an upstream workflow change could expose or misuse the secret. Merge should wait for both references to be pinned to trusted commit SHAs or for the risk to be explicitly accepted.

Poem

A new branch starts the flow,
GPG secrets pass where they must go.
Build and publish use the updated way,
Keys stay scoped by ignore rules today.
Small workflow changes mark the day.

23-23: 🔒 Security & Privacy

Verify that gpg-migration is a trusted branch.

If untrusted users can push to or modify workflows on gpg-migration, the new trigger can execute modified workflow code with access to the MOSIP GPG private key. Confirm that branch protection restricts pushes and workflow changes to trusted maintainers. Otherwise, keep secret-bearing jobs behind a trusted branch or approval gate.

36-36: 🗄️ Data Integrity & Integration

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify the reusable-workflow secret contract.

Confirm that both referenced workflows at mosip/kattu@master-java21 declare and consume the exact GPG_PRIVATE_KEY secret. If they expect another name, these jobs will not receive the signing key and the build or publish operation can fail.

⚠️ Unverified finding
Sandbox verification was unavailable.

Ignore the actual GPG key path.

The PR objective names .github/keys/mosipgpgkey_*.gpg, but this rule only matches paths containing .settings/.github/keys/. Git will not ignore a key created directly under .github/keys/.

Add an ignore rule for the exact key path. Otherwise, a future MOSIP private key can be committed and exposed.

Proposed fix

 */.settings/.github/keys/
+.github/keys/mosipgpgkey_*.gpg
