native-fips

native-fips is a skill for Claude Code from openshift-eng/ai-helpers. It costs 136 tokens per session (2,119 once invoked), scanned A, original, Apache-2.0.

A configuration workflow for using Go's built-in FIPS 140 cryptography module, a U.S. government standard for validated cryptographic implementations, instead of an OpenSSL-based setup.

In plain words
What is it for?
Use it to enable native FIPS in a new Go project or migrate an existing OpenSSL-based FIPS build, including its build settings and cgo-specific choices.
Why use it?
It helps Go projects move between these FIPS configurations and can remove the OpenSSL runtime dependency for builds that do not use cgo, Go's mechanism for calling C code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

native-fips scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Native FIPS

Configure a Go project to use Go's native FIPS 140 module (GOFIPS140). With CGO_ENABLED=0, this produces static binaries that no longer depend on the openssl RPM. Projects that require cgo should keep CGO_ENABLED=1 and adjust their FIPS setup accordingly. Works for both new projects and migrating existing openssl-based FIPS setups.

Reference

Build-time: GOFIPS140

Tells the Go compiler which FIPS 140 crypto module to embed into the binary.

Value Status ML-KEM ML-DSA Notes
v1.0.0 Validation completed Yes No Validated, stable
v1.26.0 Module In Process (MIP) Yes Yes Adds ML-DSA + better entropy
latest Alias — — Resolves to newest available module
certified Alias — — Resolves to newest FIPS-certified module

Use certified in go build as it automatically resolves to the latest certified module (currently v1.0.0). Both modules support ML-KEM (post-quantum key encapsulation), so post-quantum key exchange is available without the old DEFAULT:PQ crypto-policies stage.

Build-time: GOEXPERIMENT=strictfipsruntime (downstream only)

The downstream golang-fips/go toolchain (used in RHEL/CentOS Go Toolset) provides GOEXPERIMENT=strictfipsruntime, which adds a startup check that panics if the binary's FIPS configuration is incompatible with the host environment. This is separate from GOFIPS140 — it provides fail-closed startup enforcement, not module selection.

When migrating a downstream build from the OpenSSL backend to native FIPS on 1.26+ builders, retain GOEXPERIMENT=strictfipsruntime and add -tags no_openssl to disable the OpenSSL backend. The 1.26+ builders imply GODEBUG=fips140=auto whenever the FIPS module is compiled in, so the binary works on both FIPS and non-FIPS hosts:

CGO_ENABLED=0 GOFIPS140=v1.26.0 GOEXPERIMENT=strictfipsruntime go build -tags no_openssl ...

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

native-fips is a skill published in the GitHub repository openshift-eng/ai-helpers (121 stars, last pushed today), licensed Apache-2.0. It adds 136 tokens to every session and 2,119 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
