File Extension PEM Description:

Part of the WordPerfect program's Editor Macro, the PEM file is part of a library of Open Style settings used to improve document formatting. The PEM file format maintains WordPerfect's streaming-code architecture while allowing control strings to be recorded for later execution. Strings of commands recorded in the PEM files can be edited, saved and moved to other computers to allow users to carry their macros with them. This process is known as the Alt-keystroke facility.

WordPerfect is a venerable word processing platform that was originally developed for personal computers using the Microsoft Disk Operating System (MS DOS). It was designed to create, edit and save text files. The most common tasks performed by WordPerfect (and other early word processor applications) was printing, generally to dot-matrix and later Laser printer. Word perfect was originally a command prompt driven program, using various language based commands in concert with keyboard controls to manipulate a given file. Later versions were redeveloped for graphical interfaces.

WordPerfect was one of the leading word processor applications before the advent of Microsoft Windows. The extra developmental time necessary for the production of a graphical interface for the program, coupled with the difficult in writing for the then novel 32-bit processor architecture of the first fully Windows operating system, delayed the release of several non-Microsoft office utilities. The addition of the Microsoft Office Suite as default in most new Windows installations also displaced WordPerfect and other competing word processors from the top of the market, replacing them with Microsoft Word.

Another use of the PEM format is the Privacy Enhanced Mail program. For PEM, the PEM file contains various security information necessary for execution of secure email communication. The PEM holds public key certificates, which allows PGP encryption to be applied to emails between users who have exchanged key encryptions. One portion of the code encryption is held by the recipient after its exchanged with the sender, while the bulk of the encryption code resides with the message. The private key unlocks the mail only when they various keys match, ensuring that a message can only be unlocked by someone with all the necessary keys.
