doca-sha-offload-engine SKILL.md skillA
doca-sha-offload-engine from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use this skill when wiring the DOCA SHA Offload Engine (an OpenSSL ENGINE) into an existing OpenSSL pipeline to offload one-shot SHA-1, SHA-256, or SHA-512 (EVP_Digest) onto DOCA SHA hardware without rewriting against doca-sha. Covers engine load mechanics (`openssl engine dynamic`, `set_pci_addr` ctrl, `-engine_impl`), the SHA-224 negative test that proves offload engaged, the message-size window where offload beats CPU SHA, and engine-vs-library selection. Trigger even when the user does not…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DOCA SHA Offload Engine ## Examples - **“Can I offload SHA in an existing OpenSSL pipeline without rewriting?”** — this is in scope. Load the engine; do not start a new `doca-sha` pipeline here. - **“How do I prove OpenSSL used DOCA SHA, not CPU SHA?”** — use the SHA-224 negative test; do not treat a successful digest as proof of offload. ## Quick answer (answer from this file) 1. **Device gate first.** The DOCA SHA engine exists only on BlueField-2; BlueField-3 has no SHA acceleration engine (public DOCA SHA guide), so there is nothing to offload there: say so and stop. 2. **Load probe:** `openssl engine dynamic -pre NO_VCHECK:1 -pre SO_PATH:<engine .so> -pre LOAD -vvv -t -c`. 3. **Positive test:** `openssl dgst -sha256 -engine <engine .so> -engine_impl <file>` reports the engine was set. 4. **Negative test:** an unsupported digest (`-sha224`) must fail with the engine selected; it must not silently fall back. 5. **Performance:** compare `openssl speed -evp sha256` with and without the engine (add `-async_jobs` for parallelism). Report measured numbers only; never quote numbers from memory. ## Instructions …

How to install
mdr add nvidia/skills/doca-sha-offload-engine@sha256:9f2b3e1343ef3770The line at the top of this page pins the label git:20261028.3d06e7e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
