SignCore.CMS.UnsignedAttributes (sign_core v0.1.0)

Copy Markdown View Source

Builders for CMS unsignedAttrs — the optional set on a SignerInfo that carries data computed after signing (signature timestamps, countersignatures, etc.). The values aren't covered by the signature math.

v1 ships only the PAdES B-T / CAdES B-T attribute: id-aa-signatureTimeStampToken (RFC 3161 §3.3.4 / RFC 5126 §6.1.1) — an RFC 3161 TimeStampToken anchoring the SignerInfo's signature field.

Summary

Functions

signature_timestamp(tst_der)

Builds the id-aa-signatureTimeStampToken Attribute with the supplied TimeStampToken DER (a CMS ContentInfo per RFC 3161 §2.4.2). The TST is embedded verbatim inside the Attribute's attrValues SET — no parsing or validation happens here.

Functions

signature_timestamp(tst_der)

@spec signature_timestamp(binary()) ::
  {:Attribute, tuple(), [{:asn1_OPENTYPE, binary()}]}

Builds the id-aa-signatureTimeStampToken Attribute with the supplied TimeStampToken DER (a CMS ContentInfo per RFC 3161 §2.4.2). The TST is embedded verbatim inside the Attribute's attrValues SET — no parsing or validation happens here.
