Signature generation produces integrity signatures for protocol artifacts using SHA256 hashing. Initialize the operational context, execute the signing protocol, and output the signature for inclusion in your build pipeline or deployment process.

Yes. Signature verification validates that artifacts haven't been tampered with by comparing generated signatures against reference values. This ensures authenticity before deployment and maintains auditable provenance records.

Audit trails document signature creation and verification events, establishing a complete chain of custody. Store these records alongside artifacts to create an auditable provenance history for compliance and security investigations.

Integrity signatures cryptographically bind artifacts to their creation context. Validate signatures at deployment checkpoints to confirm artifacts match their original state, preventing unauthorized modifications across environments.

The Skill depends on sha256_hasher.py for signature generation. Provide this dependency and your protocol artifacts; the Skill handles initialization, signing, and validation without additional cryptographic libraries.

Signature verification confirms integrity but requires secure key management and consistent hash algorithm implementation. Signatures validate tampering detection only; they don't authenticate the signer's identity without additional PKI infrastructure.
