How much Poka reads

B2 Broad. The common content of the current and the common older versions is decoded. Some named features or versions are not, and are listed.

Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-shadow/src/main.rs (214 lines) and plugin.json. No unit tests or tests/samples.rs; the corpus has no .shadow, .shadowfile and .etc-shadow sample. Covers .shadow, .shadowfile and .etc-shadow. The table lists every account with user, status (locked, no password, hash), hash algorithm, a redacted hash, and the last-change, minimum, maximum and expiry fields. Judgement: B2: every entry is shown; the gaps are limits, redaction by design and fields left raw.

What Poka does not read

  • Hashes are redacted (by design)
  • The warning, inactive and reserved fields are not shown
  • Day counts are shown raw, not as dates (judgement from the code)
  • Only the first 1,000 accounts are listed

Libraries

Libraries Poka uses or has assessed for this format, with the status, licence and language the registry records.

  • pgs-files (candidate; MIT OR Apache-2.0; Rust; https://docs.rs/pgs-files) — Reads /etc/passwd, /etc/group and /etc/shadow; has a shadow module. Early 0.0.x release depending on libc, so wasm suitability is doubtful.
  • jk_etcpasswd (candidate; Apache-2.0; Python; https://pypi.org/pypi/jk-etcpasswd/json) — Parses and models /etc/passwd, /etc/shadow, /etc/group and /etc/gshadow (v0.2025.6.12). Licence from classifier; metadata licence field empty.
