Answer 1

You first need to understand the basic structure of a Multipurpose Internet Mail Extensions (MIME) body.
That is what an e-mail is. That is what mail readers create when sending mail. That is what mail readers expects and renders when receiving mail.
A mail attachment cannot be password protected via MIME itself. The MIME specs do not support password protected "boundary pieces" in a MIME body.
A MIME body can however contain multiple attachments and different types of attachment. From text and html to images and video.
It can also include a binary attachment like a zipfile. That zipfile can be protected by a password.
An import point to keep in mind that attaching an binary file to a MIME body (e-mail) means:
a) creating a MIME payload/boundary piece for that file in the mail body
b) reading the contents of that file
c) uu encoding that file (it basically needs to be 7bit ASCII and not 8bit to survive intact across networking infrastructure)
d) writing that encoded text as the attachment piece into the mail body
None of this has however anything to do with SQL or PL/SQL specifically. What is needed is a clear understanding of the mail body (MIME) that your code needs to create.
