What is P7S file?

P7S files are a file format with data about secure email messages. Such files are encrypted using S/MIME digital signatures. Only the recipient can read such a message, so you can be sure that such files are safe. It also cannot be changed during transmission. Files with the P7S extension will also contain detailed information, including the email source and recipient email.

More information

Most email programs support the P7S format. Examples include Microsoft Outlook, Apple Mail, and Mozilla Thunderbird. However, if your application does not support electronic signatures, the data from the file will be displayed as a standard attachment to the message.

A P7S file can be opened in Microsoft Outlook, Apple Mail, and other email programs. However, you will only be able to see the file's contents if you are the email recipient. You can convert this type only in special file converters that support this format.
