PDF security

Encrypt PDFs with AES-256: an opening password and permissions that block printing, copying and changes.

pdfSecurity encrypts the PDF with AES-256 (PDF 2.0 standard security). With a user password the file asks for it when opened; permissions limit printing, copying and changes in PDF readers. A random owner password is used when you give none.

createViewer(el, {
  definition, data,
  pdfSecurity: {
    userPassword: '1234',                      // asked when the PDF is opened (omit: opens freely)
    permissions: { print: true, copy: false, modify: false },
  },
});
