What is PEM file?

PEM file extension is used by certificate files to store and transport cryptographic keys, certificates and other types of data. Binary PEM files are base64-encoded and store data in ASCII text format.

How PEM certificates are used

PEM-encoded certificate files are frequently used on internet servers as they are easy to view using any standard text editor. PEM files are used for authenticating trusted website and are usually imported from a Unix-based Apache webserver. PEM certificates can also be used to send private emails as they guarantee the message has not been tempered with during transport, and that the message comes from legitimate source.

PEM format security

PEM certificate uses digitally-signed public key for security purposes. Authentication process uses public key to identify the owner of the key and confirm they are the person they claim to be.

Limited popularity of PEM format

In short time the PEM format became and IETF standard, although this status did not bring it popularity. PEM has since then been replaced by newer, more secure technologies.

Additional information

  1. PEM files are supported by OpenSSL applications.
  2. Opening PEM file with text editor clearly shows marked headers and footers code sections.

We hope we helped you solve the problem with the PEM file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the PEM file (apart from the lack of the proper application installed).

First - the PEM file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the PEM file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the PEM file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the PEM file has not been completed and it cannot be opened properly).
