Parsed CMS SignedData reduced to the fields a PDF signature reader needs.

Fields

version: u64

CMS SignedData version — 1, 3, 4, or 5 (RFC 5652 §5.1).

digest_algorithms: Vec<(Vec<u64>, Vec<u8>)>

digestAlgorithms SET — each entry is (oid_arcs, params_raw_bytes).

encap_content_type: Vec<u64>

encapContentInfo.eContentType OID arcs. For attached PDF signatures this is id-data (1.2.840.113549.1.7.1); for detached PAdES signatures it’s still id-data but the eContent octets are absent — the bytes to verify are the PDF byte ranges in /ByteRange.

encap_content_octets: Option<Vec<u8>>

encapContentInfo.eContent octets — Some(bytes) for attached signatures, None when omitted (typical PAdES / detached). The bytes here are the OCTET STRING body — no DER header, no [0] wrapper.

certs: Vec<Vec<u8>>

certificates[0] IMPLICIT CertificateSet OPTIONAL — each entry is the raw DER bytes of one CertificateChoices alternative (typically an X.509 v3 SEQUENCE; we surface every alternative shape as opaque DER so the caller can dispatch on the outer tag). Empty vec when the field was absent.

crls: Vec<Vec<u8>>

crls[1] IMPLICIT RevocationInfoChoices OPTIONAL — each entry is the raw DER bytes of one RevocationInfoChoices alternative (typically an X.509 CertificateList SEQUENCE). Empty vec when the field was absent.

signer_infos: Vec<SignerInfo>

signerInfos SET OF SignerInfo — typically one entry for a single-signer PDF, but the spec permits multiple.

Trait Implementations
