bom-signing
Signs and verifies CycloneDX BOMs using cdxgen's native JSON Signature Format (JSF) implementation via cdx-sign and cdx-verify, supporting granular component, service, and annotation signatures, parallel multi-signatures, and sequential signature chains. Use when asked to sign an SBOM, verify a BOM signature, establish BOM authenticity or non-repudiation, build an approval trail across pipeline stages, or generate signing keys.

# Sign and verify BOMs
cdxgen ships a native JSON Signature Format (JSF) implementation that goes
beyond a single document-level signature. It supports granular signatures over
individual components, services, and annotations; parallel multi-signatures via
`signers`; and sequential signature chains via `chain`.
Read [reference/safety.md](../../reference/safety.md) first.
## Key handling boundary
**Never generate, read, paste, or transcribe private key material yourself, and
never enter a passphrase on the user's behalf.** Run the signing commands with
paths the user provides, and if a key does not exist yet, give the user the
