Password-protect and encrypt PDFs

Three parameters control encryption:

• userPassword — the password a reader must enter to open the PDF. Setting it turns encryption on.
• ownerPassword — optional. Grants full access to the document, including the actions that permissions restricts.
• permissions — what a reader who opens the PDF with the user password may do. The default is ["print"].

curl --fail --show-error --output example.pdf --request POST \
  --url https://api.html2pdf.app/v1/generate \
  --header 'Content-Type: application/json' \
  --header 'X-API-Key: <your-api-key>' \
  --data '{
    "html": "https://example.com",
    "userPassword": "user",
    "ownerPassword": "owner",
    "permissions": ["print", "modify", "copy"]
}'

The values permissions accepts are:

• print — printing.
• printbest — high-resolution printing, when print is also allowed.
• modify — modifying the document, signing it and changing form fields.
• copy — copying content.
• edit — commenting.
• fillform — filling in form fields.
• extract — copying content for accessibility.
• assemble — rotating, inserting or deleting pages, and managing bookmarks and thumbnails.

Encryption uses 128-bit AES. See Encryption in the documentation.
