Talisman "Potential secrets detected" blocks the push in CI

Talisman scans staged changes for secret-like filenames, content patterns, and high entropy. When it finds a match it prints "Potential secrets detected" and exits non-zero, blocking the commit or push.

What this error means

Talisman prints a table of "Potential secrets" with the filename and reason (for example "The file name ... failed checks against the pattern") and fails the step.

Common causes

A secret-like file or content was staged

Talisman matched a filename pattern (such as *_rsa), a content pattern, or a high-entropy string in the staged changes.

A false positive on a fixture or key-shaped value

A test key file or long random token trips a pattern even though it is not a real secret.

How to fix it

Remove a real secret or add a checksum ignore

1. Inspect each flagged file and reason in the report.
2. If it is a real secret, remove it, rotate it, and load it from a secret store.
3. For a verified false positive, add a checksum-pinned entry to .talismanrc.

fileignoreconfig:
  - filename: tests/fixtures/id_rsa
    checksum: 4f1b...pinned-sha256

Generate the ignore entry from Talisman

Let Talisman compute the checksum so the ignore stays valid only for the exact file content you approved.

talisman --checksum='tests/fixtures/id_rsa'

How to prevent it

• Pin ignores by checksum so edited files are re-flagged.
• Rotate any real secret Talisman catches.
• Run Talisman as a pre-push hook so pushes are checked before CI.
