seekrit GitHub Action

Load secrets from seekrit into your GitHub Actions job — resolved, decrypted on the runner, masked in the logs, and injected into $GITHUB_ENV so every subsequent step just sees them as environment variables.

seekrit is end-to-end encrypted: this action decrypts your secrets locally using the private key carried by your service token. The seekrit API never sees plaintext.

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: seekritdev/github-action@v1
        with:
          token: ${{ secrets.SEEKRIT_TOKEN }}

      # Later steps see the secrets as environment variables:
      - run: ./deploy.sh # e.g. $DATABASE_URL, $API_KEY, … are set

Store your service token as an encrypted Actions secret named SEEKRIT_TOKEN. A service token is bound to a single application environment, so there is nothing else to configure — it resolves its own org, app, environment, and composed groups.

Inputs

Input	Default	Description
token	(required)	seekrit service token (skt_…). Pass ${{ secrets.SEEKRIT_TOKEN }}.
api-url	https://api.seekrit.dev	seekrit API base URL.
with	""	Group→environment overrides, one group:env per line (or comma-separated). Mirrors the CLI --with.
export-env	true	Inject each secret into $GITHUB_ENV for subsequent steps.
set-outputs	false	Also expose each secret as a step output (steps.<id>.outputs.<NAME>).
mask	true	Register every value with the runner (::add-mask::) so it is redacted from logs.
prefix	""	String prepended to every injected variable name.
include	""	If set, inject only these names (comma/newline separated).
exclude	""	Names to skip (comma/newline separated).

Outputs

Output	Description
secrets-count	Number of secrets injected.

Examples

Consume secrets in later steps

steps:
  - uses: seekritdev/github-action@v1
    with:
      token: ${{ secrets.SEEKRIT_TOKEN }}
  - run: |
      echo "connecting to the database..."   # $DATABASE_URL is set & masked
      ./migrate.sh

Namespace with a prefix, and filter

- uses: seekritdev/github-action@v1
  with:
    token: ${{ secrets.SEEKRIT_TOKEN }}
    prefix: "SEEKRIT_"          # -> $SEEKRIT_DATABASE_URL, ...
    include: DATABASE_URL, API_KEY

Compose a group at a specific environment

- uses: seekritdev/github-action@v1
  with:
    token: ${{ secrets.SEEKRIT_TOKEN }}
    with: |
      platform:staging
      payments:staging

Read as step outputs instead of env

- id: seekrit
  uses: seekritdev/github-action@v1
  with:
    token: ${{ secrets.SEEKRIT_TOKEN }}
    export-env: "false"
    set-outputs: "true"
- run: echo "count=${{ steps.seekrit.outputs.secrets-count }}"
  # individual values: ${{ steps.seekrit.outputs.DATABASE_URL }}

Prefer masked environment variables (export-env) over step outputs where you can — outputs are stored in the workflow run and are a slightly larger surface than env masking.

How it works

1. The action reads your skt_… service token (which is the private key — it is never sent).
2. It calls GET /v1/resolve, receiving ciphertext only: the ordered secret layers (composed groups → application environment) plus a per-layer data key wrapped to the token's public key.
3. It unwraps each data key and decrypts every secret locally (ECDH P-256 → HKDF-SHA256 → AES-256-GCM), applying the same precedence as seekrit run — the app environment wins over composed groups.
4. Each value is masked (::add-mask::) and written to $GITHUB_ENV / step outputs.

Precedence, formats, and the zero-knowledge model are documented at https://seekrit.dev/docs.

Security

• Zero-knowledge. Decryption happens on the runner. The API only ever holds ciphertext and public keys — never plaintext, private keys, or passphrases.
• Masked by default. Every injected value is registered with the runner so it is redacted from logs (multi-line values are masked line by line). Leave mask on.
• No third-party runtime dependencies. The published dist/ bundle contains only this repo's own code — no node_modules are pulled at action runtime — so the code handling your secrets is small and auditable.
• Scope your token. Grant each token only the environment it needs, and rotate/revoke from the seekrit dashboard. A leaked CI token is contained to a single environment.
• Treat injected environment variables like any other CI secret: they are available to every step in the job, including third-party actions you invoke afterward.

Versioning

Reference a major version so you get non-breaking updates:

- uses: seekritdev/github-action@v1

Pin to an exact release (e.g. @v1.0.0) or a commit SHA if you require immutability.

Development

npm ci
npm run typecheck
npm test          # decrypts golden vectors from @seekrit/crypto (crypto is byte-compatible)
npm run build     # bundles src/ -> dist/index.js (esbuild); commit the result
npm run lint

The bundled dist/index.js is committed and must stay in sync with src/ — CI fails if it drifts. The crypto is a vendored, decrypt-only port of the canonical @seekrit/crypto; the golden-vector test (test/fixtures/vectors.json) is generated by the real implementation and pins byte-for-byte compatibility.
