Default Adobe Acrobat Passwords

When you assign a password to an Adobe Acrobat document, does it encrypt the
document? If not, the data would still be readable using a third party
Acrobat clone that doesn't respect passwords?

It looks like you are wrong. When I assign security to a PDF in PDF Writer
Standard 9.0, it indicates that it is encrypting the entire document with
AES-128.

There's several different passwords and security/encryption options in
PDF documents.

You can set the "Owner Password" that restricts various rights within
the document, ie. opening, printing, copying text, etc. etc.
Or you can do full-blown encryption of the PDF file, or parts of the
PDF file, leaving most of the structure intact.

Since almost nobody wants to force the end-user to type in a complex
password to unencrypt a document, many times people set the "owner
password" beliving it does some sort of encryption, when in fact it
provides almost no protection at all.

So to answer the OP, yes, you can encrypt the document, but you have
to be careful to select the correct mode. Also, encrypted documents
will always require the end user to type in a password to open it.

Why would someone put a password on a document if they didn't want to
force the reader to type it? What's the point?

In Adobe Acrobat Standard 9.0, the Security Settings screen has an option to
encrypt. As long as you select Adobe format 7.0 or later, you get a
minimum of AES-128. No one is going to crack that, and it is encryption.

The weak point is then the password used to encrypt the key. If you select
a four character password, that will get broken by a cracking tool in two
minutes. If you select a 14 character password that is not a dictionary
word or phrase, then unlikely anyone is going to be able to unlock the file.

What does "Tech here" mean in this context? In a previous message you
said "This is Tech", which also made no sense. Is encryption difficult
technology?

YES...

I still don't get it. What is "a Tech" and what does it have to do with
the question about Adobe Acrobat?
