}

Options for creating a PDF signature.

Fields

signer_name: Option<String>

Signer name to embed in the signature.

reason: Option<String>

Reason for signing.

location: Option<String>

Location of signing.

contact_info: Option<String>

Contact information.

digest_algorithm: DigestAlgorithm

Digest algorithm (default: SHA-256).

timestamp_token: Option<Vec<u8>>

RFC 3161 timestamp token (DER-encoded). Caller is responsible for obtaining this from a TSA server. Use create_timestamp_request() to build the request, send it via HTTP to a TSA, then parse_timestamp_response() to extract the token.

visible: bool

Whether to create a visible signature appearance.

appearance_rect: Option<[f64; 4]>

Rectangle for visible signature [llx, lly, urx, ury] in points. Defaults to [0, 0, 200, 80] if visible=true and rect is None.
