| S/MIME Compressed Message | N/A | Encoded&Encrypted Files |
The .P7Z file extension is an encrypted message created using the S/MIME protocol and compressed with the high-performance compression tool 7-Zip. Developed by Igor Pavlov, 7-Zip is a free and open source compression software for Windows, MacOS and Linux that provides superb compression of files for easy transmission and storage.
S/MIME (Secure Multipurpose Internet Mail Extensions) is a security-enhanced communication protocol that is used to authenticate, encrypt, and digitally sign messages over the Internet. The .P7Z file extension will be created when an S/MIME message is compressed using the 7-Zip utility. Other popular file formats used for encryption and digital signing of emails are .PGP, .GPG, and .P7S.
Security Features of P7Z File Format
The .P7Z file format provides excellent security, as it integrates two different encryption algorithms to protect messages. The S/MIME protocol employs PKCS#7 Protocol for encryption which is considered to be one of the strongest encryption algorithms available and provides industrial-grade authentication. 7-Zip, on the other hand, adds an additional layer of protection with its high-performance compression techniques.
How to Open a P7Z file?
Most email programs such as Microsoft Outlook, Thunderbird, Windows Live Mail, etc. support the viewing of P7Z (S/MIME Compressed Message) files. The user must simply double click on the.P7Z attachment in order to open and view its contents. Alternatively, you can use a dedicated email security program such as OpenPGP or Gpg4win for opening these files as well.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .P7Z) 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 .P7Z 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 .P7Z 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 .P7Z 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 .P7Z extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .P7Z file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .P7Z 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 .P7Z file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .P7Z file) will be extended to the maximum.
It is also good to check
- if the .P7Z file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
