Thank you Jonathan,
I was begining to get to the same conclusion after some days of google search. My problem is indeed to get the information from the client system.
Now I must decide if it is better to make the user upload it everytime (user gets annoyed), just upload one time and save on the server the data (unsecure), or upload onetime and hold the file in the html by the use of either session or hidden inputs (site opens slowly).
Anyone has another option I haven't explored to this problem?
If you want to encrypt/decrypt something specific to a user why don't you prompt the user to enter a key, and then use they supplied key to encrypt/decrypt. This will function somewhat like a password - if the user doesn't supply the same key that was used to encrypt the data, the decrypt will not work. Jonathan

Hello Jonathan,
I saw your reply to this message about uploading a file, and I
thought
you could help me. I have a database in my server where people from place information into. Some information is confidential and i would like to encrypt, leaving the key of encription inside the computer of the person who placed the information there.
I was planning in leaving a file (.txt) in the outside computer and when he wants to place a information in my database, I would call a python script to encrypt it, using the key on the .txt file. After when he wants to read it again, i read the txt file and reverse the process.
My problem with the way using a page-template is that i would have to ask the person to open upload the file everytime he wants to see that info....or hold the key in my server what is also not a good idea.
Is there a way to read the file directly from a python script?
If you want to read a file from the server filesystem then you will need an External Method, but this is very easy to do (googling will get you lots of help and you can also find help in the Zope Book).
If the file is on the client system then you will have to ask the user to upload the file each time.
Jonathan
