# `SignCore.CMS.OIDs`
[🔗](https://github.com/utaladriz/pkcs11ex/blob/v0.1.0/lib/sign_core/cms/oids.ex#L1)

Well-known ASN.1 object identifiers used by CMS / PKCS#7 / PKCS#9.

All OIDs are returned as the tuple form OTP's ASN.1 runtime expects
(e.g., `{1, 2, 840, 113549, 1, 7, 2}` for `id-signedData`).

Centralising these prevents mistyping and gives one place to look up
the dotted-decimal form a verifier might log.
