Scan incoming commits for secrets with Talisman

Detect secrets with Talisman action

This action uses Talisman to scan the incoming (pushed) range of commits for accidentally added secrets and sensitive information. It mimics a pre-push hook for this, thus it works nicely with a local git hook in tandem, that is as a fallback, last line of defense.

Example usage

steps:
  - name: Detect secrets with Talisman in incoming commits
    uses: carhartl/talisman-secrets-scan-action@v1.4.0

Caveat

When using this along with the actions/checkout@v2 step you'll need to configure it to avoid a too shallow clone:

- uses: actions/checkout@v2
  with:
    fetch-depth: 0

Otherwise you may run into Talisman erroring out while it's trying to execute git with an invalid revision range:
