Aspose function

Dear Sir or Madam,

Greetings!

  1. What do we want to do?

We want to protect some documents, including but not limited to word, excel, mail, pdf, etc.
For example, adding read-only permission to word and the password to open the file, these actions can be done manually by mouse operation, but we need to use the program to achieve automation

  1. Regarding ASPOSE, what functions do we care about?
    a. What types of files can be protected, such as office documents and other document types
    b. We can implement protection types. Different types of document protection may be different. For example, word copy supports setting open passwords and setting read-only; mail (mail everywhere.msg documents) settings do not allow forwarding

Looking forward to hearing from you.

Best Regards,

Josie Li
