I am aware words password protection is pretty lame and can be easily circumvented?
How do adobe PDF's password protection options compare?
If both are weak, is there an alternative FREE way to perhaps protect these files before sending them off via email, perhaps utilities built within compression tools?
I need some solution whereby the recipient of the email which contains an attachment of either PDF or docx/xlsx doesnt need to install any special software to open and gain access to it, above and beyond the password.
I am also aware that zip fles may cause issues with mail filters - which may cause an issue?
