Hi Support,
Want to know if Aspose.HTML supports AES256 encryption in PDF.
We have a requirement to use this encryption type in our PDF.
We are afraid that Aspose.HTML cannot be used to encrypt PDF files. It is specialized to process HTML documents. You can please try Aspose.PDF which offers encryption functionality for PDF files. It allows RC4/AES encryption methods with 40, 128, 256 key sizes. Please feel free to let us know in case you need more information.
