What is p7m format

Before taking a look at the best solutions for opening this type of file, it is important to understand what it is. When you find yourself opening a file in .p7m format , you will be opening a file that has been digitally signed. It is often associated with electronic invoices, but you can also find the same format in a text document, a spreadsheet, any computer document, an image or any text in which a digital signature has been affixed.

As you can imagine, a file of this kind does not have the same value as a traditional text document, perhaps written in Word or PDF , but inserts a digital signature inside which certifies its importance, as well as a legal value.

How to open a p7m file

Specifically, the digital signature, when associated with an IT document, has the ability to certify the identity of the person who transcribed the signature, thus ensuring that the text within it has not been modified, effectively highlighting the legal validity. Just like the PEC , which unlike a traditional e-mail is certified, documents in .p7m format also have legal value, a condition which binds you to various duties, but also to many guarantees.

From a technical point of view, although this format is increasingly widespread, you will need to rely on dedicated software to be able to view it on the screen. Unlike many paper documents, the .p7m format is bound to an encrypted system which makes it more secure. Imagine receiving an electronic invoice, you can only open it with software compatible with this format. In practical use, in addition to equipping yourself with the specific program, you won’t have to worry about other specifications. In fact, the software itself will then convert the format into a text file , showing it on the screen as a common Word file or a PDF.

Now that we have a clearer idea of ​​what a .p7m format file is, it is interesting to analyze what are the most efficient software for this operation.

Dike GoSign

One of the most downloaded programs to open files in the .p7m format is Dike , developed by the Infocert company and downloadable completely free of charge, both on the Windows and macOS versions. When you access Dike’s functions, you will not only be able to take a look at the digitally signed text, but you will also be able to affix one or more digital signatures if you need to. Go to the official Infocert website and click on Download , once the procedure is complete you will need to install the software and import the .p7m file you wish to view.

You can also select the program by right clicking on the file and choosing Open with Dike , it will open directly in the software. By clicking on the Report option you can also verify that there are errors in the digital document.

ArubaSign

If you use the Aruba platform for various services, from electronic invoicing to digital signatures, then you would probably love ArubaSign . Although the Aruba site, in most cases, offers you paid services, with ArubaSign you can access files in .p7m format for free. But how to open p7m files with Aruba ?

DigitalSign Reader

Many users, especially those who have a SME (Small and Medium Enterprise), love to use DigitalSign Reader to quickly view their files in p7m format. This program was developed by CompeD and is, as you can tell from the name, a real p7m document reader. Fortunately, however, it is not limited only to reading files in this extension, but can also implement additional functions, such as adding an electronic signature or accessing advanced activities.
