The .P7S file type is a binary file format associated with digital signature creation and verification. Most commonly, P7S files are used for email message file signatures, enabling secure communication over the internet. This file type is also sometimes referred to as Detached Signature (.P7S) or Digitally Signed Email Message (.P7S).
How It Works
The encryption technology of .P7S files is based on Public Key Infrastructure (PKI) functions, which uses two interrelated cryptographic keys to encode and decode digital information. The originator's private key is used to create a signature on the file, which is then associated with a single public key. When other users want to verify the identity of the originator, they use this public key. Cryptography algorithms within Microsoft Outlook, Mozilla Thunderbird, or other compatible programs can be used to read and verify a .P7S file’s digital signature.
The .P7S format can be opened with several applications for reading and outputting digital signatures such as from Xen recognized Viewers, SecureZIP Reader, and powerMime products. Files in the same family as the .P7S format are the .P7M, .VSDX, .VSIX, and VSSIGNATURE.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .P7S) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .P7S extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .P7S file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .P7S extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .P7S extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .P7S file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .P7S file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .P7S file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .P7S file) will be extended to the maximum.
It is also good to check
- if the .P7S file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
