They are useful for preventing access to bots, hackers or computer viruses and are available for both Windows and Mac computers, offering the user versatility in their use and the requirements are accessible to all audiences, as they generate keys that the user is the one who decides who to share it with.

To create files in this format, which contain information you need within the reach of limited people, you must first of all have Adobe Acrobat installed on your computer, since it is the program that will allow the user to open them, either on a specific device or network system to which it is connected.

First, we need to know that to create a file in this format we work with what is called a Digital ID, which is a certification similar to a driver's license, which indicates that it contains personal data such as first names, surnames, email address, signature and even expiration date.

When creating a Digital ID, has two keys, public and private, which are the ones that encode and decode the information present in them, and in turn give the necessary formal trust when carrying out online transactions; you don't need a digital ID or a PFX certificate to add notes or edit a PDF.

How to create a PFX file

Creating these certificates is a relatively simple process, but you have to keep in mind that it is impossible to recover a password if you have lost it, so keep it in a safe space where unwanted third parties do not have access; If, on the other hand, it is a third party who has granted you the certificate but you have forgotten your password, please contact us to recover it.

First, run Adobe Acrobat on your computer, and click the button "Advanced", which will show a series of options, and you need to click " Security settings ", Once the section, click" Digital ID " and then" Add digital ID ", After clicking on" ID I want to create now ".

Once you have completed these steps, click on " Forward" and will allow you to choose a location that you feel is safe and convenient to store yours ID, click Next again and choose " New PKCS # 12 digital ID file “, Whose purpose is to save the encryption data in a PFX file, which will allow you to share it later.

Uses and characteristics of a PFX file

Generally, these files are used by small and medium-sized businesses for legal matters that require a signature during transactions of trustworthy and legal matters and have a lifespan of up to five years of validity, so you won't have to worry about creating a new one for now. .

On computers that have a version of Windows, they will be in the format PFX, while on computers Mac OS, they will be in the format .p12, although the transfer between operating systems can be done without problems, as Adobe Acrobat has enough intelligence to identify them both and transform them without further protocol.

Although the most recommended, for security and protocol reasons, is to use Acrobat like this, there are other programs that can open files in PFX, like ad example FileMagic, a universal file viewer that would allow viewing of the file and its subsequent use, for which we emphasize that the use of the PFX is kept suspicious.
