File extension.P7MCategoryDocument FileDescriptionP7M is a file format used for digitally signed email messages in the S/MIME (Secure/Multipurpose Internet Mail Extensions) protocol. The format is used to ensure the integrity, authenticity, and confidentiality of email messages, providing a way to protect sensitive information in transit.P7M files contain both the original email message and its digital signature, which is created using a public key infrastructure (PKI) system. The digital signature provides a way to verify the identity of the sender and ensure that the message has not been tampered with during transmission.To open a P7M file, you typically need a software application that supports the S/MIME protocol, such as Microsoft Outlook or Mozilla Thunderbird. These applications can decrypt the P7M file and display the original email message, along with any attachments, in a readable format.Overall, the P7M format is an important tool for ensuring the security and privacy of email communications, particularly for organizations that need to protect sensitive information such as financial data, medical records, or personal information.Associated programsTotal Mail ConverterDeveloped byMIME typeUseful linksPDF FileFile extension.PDFCategoryDocument FileDescriptionAdobe Systems Portable Document Format (PDF) format provides all the contents of a printed document in electronic form, including text and images, as well as technical details like links, scales, graphs, and interactive content.You can open this file in free Acrobat Reader and scroll through the page or the entire document, which is generally one or more pages.
