der.ts checks DER byte by byte. cms.ts reads the CMS signature and the RFC
3161 token of spec v0.11 29.10 and 29.11 with the closed table of
algorithms: RSA PKCS 1 and PSS with BigInt, ECDSA with the arithmetic of
@noble/curves, no new package. securitycms.ts gives F1, F2, F5 and F6 with
the signers named, and S1 to S5 with the authority of a valid seal.
evaluateSecurity returns them with their detail, and verdictLines writes the
lines of F6 and S4. The 22 cases of security_cms.json and the fixtures
format3_signed_cms and format3_sealed give the verdicts, the signers and the
seal of the Go reference. testing/cmsbuild.ts builds signatures and tokens
with WebCrypto for the hostile cases ported from the Go tests, and the
pending mechanism of the first sync is gone. npm run verify passes.
