So are you looking for a way to automate the process so the password doesn't have to be manually entered, or something else?
Thanks for the response George,
The goal automate creating the letter, creating a pdf file from the letter and based on customer number have the last four digits of the SSN used as the password.
You should include more details about how you're generating the PDF. I'm not aware of a way to automate setting password security with Acrobat in the way you want, but there is other software that can.
This isn't really a job for Acrobat, but for some heavy duty software set up by programmers. I have no recommendations, I'm just pretty sure Acrobat is too lightweight for your needs.
It really depends on where the source data is coming from, but this type of workflow is relatively easy to implement with a language such as PHP or Perl - these include libraries for most platforms that will create PDFs and allow security to be applied, and of course they can read from databases.
Thanks everyone for your replies.
We are using an in-house app to create a html smtp email message, due to some regulation changes we will need to secure the letter/document with a password.
We do have Acrobat Pro Xi and were not sure if Adobe had anything that would allow us to do the above.
I thought I would ask the experts for some guidance.
It's worth mentioning that this not how such a problem would normally be solved.
It is also weak, if the regulations require high security. If someone intercepts a PDF, they can try a "dictionary attack" and eventually crack the PDF. If they know it is a 4 digit password, this security is as good as useless, and would be cracked by anyone with motivation in under a second.
The normal way to send secure personal email is to have a web site which operates a secure mailbox for each user, with a password. This can be made much more secure by techniques such as blocking the account after several password failures. You can send an email telling your users that they have a new secure message, and that they can visit for it. Warning: though it is the most obvious thing to do, don't include a link that your customers can follow to login! And tell them you will never do so! This provides protection against phishing.
Probably, if you are looking for security, and you are following regulations and need to be seen to have done so, you should employ a professional security consultant to write a written report.
