Explanation¶

Understanding-oriented material: what sigillum is, how it is put together, and the reasoning behind those choices.

sigillum is a pure, standalone signing/verification CLI. It owns almost no logic of its own — it wires together upstream modules and ships the signing backends. That thinness is deliberate, and the pages below explain why.

• Components & architecture — the module stack (sigillum → go/signing-cli → go/signing + backends) and how the pieces fit together.
• Concepts — why sigillum exists as a separate tool from gtb, and the build-time backend blank-import model.
