Unfortunately, apart from Apple Mail, Android currently does not have methods to open P7S files with digital signatures. However, there are many options available for computers. The file can be opened and accessed on a mobile device after it has been sent to the client.
A P7S file is an email message with a digital signature. It can be used to send secure emails that only the intended recipient can view. P7S files verify the origin of the email and ensure that it has not been modified during transit.
To convert a P7M file to PDF, follow these steps:
- Open the software associated with the P7M file to transform it into a PDF file.
- Choose the "Print" option from the File menu.
- To save the document in PDF format, select the "Print to File" option.
You can read files with the P7M extension using appropriate software. Dike is one of the most popular software programs for reading P7M files. If it is not already installed, you can download it for free on your computer.
To access information about the digital signature using Postecert, you need to first access the service’s website. Then, click on the "Select file" button and choose the P7S file to examine through the suggested panel.
To open a notarized P7M file, you need to verify the validity of the signature and then read the content using appropriate programs. Dike, a free and easy-to-use program that allows you to open P7M files and verify their validity, is one of the most commonly used programs.

To use P7M files on Android, you need to download one of the numerous dedicated apps for this purpose, such as "Visualizzatore fattura elettronica."

A message in OpenSSL S/MIME format is known as an Smime file. S/MIME (Secure Multipurpose Internet Mail Extensions) is a convention for encrypting and digitally signing MIME data. Extensions for OpenSSL S/MIME messages include:
- .p7m
- .p7s
- .p7b
- .p7c
- .p7r
- .p7d
The default file manager on Android may not always be able to display XML files. After our tests, we suggest using the "File Manager" application, which can be downloaded from the Play Store.
To download Dike on a computer, visit the official InfoCert website. Look for the "Download GoSign" section and click on the "Download Windows" button.
To view a signed document, launch Dike Gosign and click on the "Verify" button. The system will verify the signature and display the result after selecting the file of interest.
