Changelog

0.1.1

• dart format applied to the whole codebase (no functional changes).
• Added GitHub Actions CI (analyze, format check, tests on Linux/Windows).

0.1.0

• Initial release: PAdES-B-B (/adbe.pkcs7.detached) signing of existing PDFs as an incremental update, pure Dart (pointycastle + pkcs12_parser).
• Reads classic xref tables, xref streams, /Prev chains, hybrid /XRefStm, and object streams; writes the update xref in the original's style.
• RSA + SHA-256, DER-sorted signed attributes, certificate chain embedded, invisible signature field, multiple-signature support.
• Typed error taxonomy (encrypted input, DocMDP P=1, unsupported filters, oversized CMS).
