It is possible to digitally sign and encrypt a PDF file in a manner to be seen by any PDF reader.
But when you try to do it in the available software, you usually face problems such as software that is too complicated to sign and secure, signatures that are not visible or not invisible, few options for signing, low flexibility in positioning the signature on the page, few characters available to define the reasons, only a single mode of "stamping" visible signatures, lack of a company logo option, and so on.
Considering these facts, and since ISO 31000, 32000-1 and 32000-2 set strict standards for encryption and digital signatures, why couldn't OBAKE accomplish this, following the same usability provided in its functions?
Now, you can quickly and easily sign and protect the PDF files in both ADVANCED and BUSINESS versions.
