Overview
What is a PGP file? A PGP file is a security key or digital signature that verifies a user's identity. It is used to decrypt a file encrypted by Pretty Good Privacy software. PGP files ensure that only authorized users can open protected files.
More Information Pretty Good Privacy is an encryption program used to encrypt and decrypt emails, texts, directories, and other files. When encrypting and decrypting files, Pretty Good Privacy uses a variety of public and private security keys. Private keys are saved in PGP files. While Symantec owns Pretty Good Privacy, an open standard version of Pretty Good Privacy, called OpenPGP, is used by other encryption software. Therefore, some PGP files may be created by encryption programs other than Pretty Good Privacy.
