It might be a slight mistranslation.
1. Open the PDF in Acrobat and check File > Properties. Look at the
Security tab. (Or the translation). Make sure that the security method

thanks for the quick reply. You are actually very correct. The document did not need a password to read but it was still had method of protection set to "password".
Just another question concerning this subject. The problem here is that it is actually an Invoice that a client wants to archive. To archive we transform it to PDF/A. However, we have no control over how the document is protected as we never know where an invoice comes from. The document can be read so I can't understand why we can not transform it to PDF/A?
Is it not possible in this case to transform the PDF to PDF/A ? Any ideas or thoughts you have on the subject is very welcome
A document can be secured for several different operations. For example you can set a password to prevent document changes, and not set one for document opening. This would mean that others can look at the document, but they would not be able to change the document without knowing the password.
Since transforming the document into a PDF/A involves changing the document, you will require the password to make a change.
Besides that, the PDF/A specification insists that documents are unencumbered. PDF security of any kind is not allowed. You will need to completely remove all passwords before you can have a PDF/A compliant document.
If you know the password, you can use the removePDFPasswordSecurity operation in LiveCycle ES to remove the password before you convert it to PDF/A. If you don't know the password you don't have many options.
There is a security point underlying this.
You can have a PDF with password security, and no password to open,
but a password controlling changing settings. This will have security
options set like "no printing".
It would be quite wrong to convert this to a PDF/A file without asking
for the control password, because PDF/A files must have security
removed, and this may violate the intentions of the person who made
the PDF. It must be made very clear to people using or providing for
this service, contractually if necessary, that secure files are NOT
acceptable. This is a very common scenario in many situations (e.g. in
professional printing too).
many thanks for both your replies and for clarifying this for me.
Have a nice weekend
