Decrypt EPUB File using Owner Password via .NET

Before converting EPUB to FLATOPC, if you want to decrypt your document you can do it by using the API. In order to decrypt the PDF file, you first need to create a Document object and open the EPUB using the owner’s password. After that, you need to call Decrypt method of the Document object. Finally, save the updated file using Save method of the Document object.

Document document = new Document("Decrypt.epub", "password");
// decrypt EPUB
document.Decrypt();
// save the decrypted document as doc 
document.Save("Decrypt_out.doc");

Create ReadOnly FLATOPC- File via .NET

In order to protect your FLATOPC from editing and to prevent other people from editing sensitive and confidential information in your document, you can also set the protection of the document using the API. You can limit the ability to edit a document and only allow certain actions with it. This can be done using Aspose.Words for .NET API. It enables you to control the way you restrict the content using the ProtectionType enumeration parameter. You can set your document to read-only by using the following lines of code.

Document document = new Document("input.doc");
// apply document protection and set protection password
doc.Protect(ProtectionType.ReadOnly, "password");

document.Save("output.flatopc", SaveFormat.FlatOpc);
