API key

PMAK-prefixed API key: 24 hex bytes, a literal "-", then 34 hex bytes (59-byte body); sent in the X-API-Key header.

redact-secret#310 (product PR #668) landed on the product main after 0.1.0-beta.6; the pinned published package predates it. The provider page documents only the header, so the grammar is tool-corroborated (T2).

New pipelineAuthority

Built from the new pipeline

The new pipeline is the authority for credential qualification. These numbers are read from the qualification view derived from the official credential-eval run of the public-evidence-snapshot population. The regression and policy populations keep their own counts on the qualification pages and are not added in here.

Authority: new
Population: public-evidence-snapshot
Engine: credential-eval 0.1.0-alpha.16
Evidence: snapshot-2026.10.06.4

Authorised for: @redact-secret/core@0.1.0-beta.14

Maintainer-reviewed (independent review pending)

598 fixtures of the 7,041 in evidence release snapshot-2026.10.06.4 carry this label. They are counted in the numbers on this page.

Passed the project’s own verification (source evidence, automated checks, recorded counter-arguments); not yet independently reviewed.

OpenRedaction default (all patterns): not measured in this run (optional)

The default (all-pattern) profile is slow and noisy for credential evaluation: personal data and resource identifiers dominate its findings, and its last official measurement took 7 minutes of scanner time on a population the credential profile scans in seconds (its methods run takes 40+ minutes), so it is a manual measurement and never blocks other scanners or core verification (#763). Its earlier results stay as history with their run identity; the credential profile is a separate scanner, never spliced with it.

Last measurement: policy-corpus@linux-x64 (configuration sha256:2451ce7bf380), public-evidence-snapshot+methods@linux-x64 (configuration sha256:d47d081ce5fb), public-evidence-snapshot@linux-x64 (configuration sha256:2451ce7bf380), regression-corpus@linux-x64 (configuration sha256:2451ce7bf380) · engine 0.1.0-alpha.5 · recorded 2026-10-05 · retained record, no longer listed by the run registry. It stays labelled with that run identity and is never combined with another profile or another run.

OpenRedaction credential profile (33 types): not measured in an official run (local exploratory diagnostics only: see ADR)

The credential profile is the comparison profile chosen in docs/decisions/2026-10-06-choose-the-openredaction-credential-bearing-profile-as-the-comparison-scanner.md. It is optional in the official run class because no pinned engine configuration measures it yet: making it required would refuse every official view until the owner approves the one profile-only run. Its own history starts with that run; nothing of the default's is reused for it.

No earlier measurement of it is recorded. Nothing is shown in its place.

Official measurement: pending: requires owner approval (one profile-only run; see the decision).

Benchmark dossier notes

From the provider dossier, as written. The evidence level above says how well the format is backed; a fact the dossier does not record is not shown.

Shape: PMAK-, 24 lowercase hex characters, a literal -, then 34 lowercase hex characters (59-character body, 64 in all).
Basis: T2. gitleaks (PMAK- + 24 hex + - + 34 hex) and Nosey Parker agree on the structure; trufflehog corroborates only the prefix and a 59-character body. Postman's own Insights Agent redaction config fixes the same structure, which is provider-owned code but not documentation. 31 of 33 public-code candidates matched and none had a 35 to 36 character second segment; one unsourced proposal says 34 to 36. Uppercase hex is outside the benchmark claim.
Issuance: Postman account settings; expiry is set when the key is created. Not attempted.
Contract in core: detector-families.md (postman_api_key, always redacted).

In run order. Counts are what each scanner recorded on this family's fixtures, whichever rules it has; a scanner with no rule for the family has nothing to report on it.

Benchmark dossier questions

Things the sources do not settle. They are listed so nobody reads them as settled.

Open caveat: Postman's docs state no PMAK- grammar (only the header). The 24 + 34 hex structure comes from scanners and Postman's own redaction config; no issued key has been measured.

Looks like it, but isn't

Values the dossier records as resembling this credential without being one.

Collisions: the Insights Agent config also scrubs a bare PMAK- + 24 hex, which is the id part of every full key, so the benchmark keeps that fragment as a near miss and not a credential. PMAT- is a separate credential.

Scanner rules for this family

Mapped by hand (reviewed 2026-09-30) from each scanner's pinned rule file, never from what a scanner found on the fixtures.

Peer scanner rules that target this family
Scanner	Rule	What the rule matches
