Description: Digitally sign PDF documents with a 'PKCS#12' keystore and
        verify their signatures. Signing produces a detached 'PKCS#7' /
        'CMS' signature ('adbe.pkcs7.detached') over the document and
        is applied as an incremental update, so existing signatures
        remain valid. The cryptography and PDF manipulation are
        performed by a bundled, pure-'Rust' backend (the 'pdf_signer'
        crate); no Java runtime, 'OpenSSL', or external command-line
        tools are required. Visible signature appearances with custom
        text are supported.
