File extension .P12
|PFX File (Personal Information Exchange)||RSA Laboratories||Web Files|
The P12 (Personal Information Exchange File) file extension is related to a security certificate used for authentication and encryption. The file type stores a private key identified through the X.509 Public Key Infrastructure, which plays an important role in safeguarding data between two parties. In most cases, P12 files will include associated certificates as well as the security key, creating an encrypted package.
The encryption technology used within a P12 file is based on public-key cryptography or asymmetric cryptography. This type of encryption technology creates two keys, enabling each sender and recipient to build an exchange of messages securely and prevents unauthorized users from deciphering the protected data.
In most cases, the P12 Standards body responsible for maintaining these certificates and encryption standards is the International Telecommunications Union (ITU). These files also use associated algorithms such as RSA and DSA.
Usage and Similar File Extensions
P12 files are mainly used to transfer confidential information securely across a network with individuals who have compatible authentication protocols, such as software like Microsoft Internet Explorer or Mozilla Firefox. Additionally, other similar file extensions like .pfx, .pem, and .cer are also used depending on the type of certificate required.
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .P12) 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 .P12 extension.
When choosing the software we can select the system to use this software every time.
Using it for the first time it is good to check whether the .P12 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 .P12 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 .P12 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .P12 file. Sometimes you have to repeat the operation several times.
If none of the programs listed by us to work with the .P12 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 .P12 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .P12 file) will be extended to the maximum.
It is also good to check
- if the .P12 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
