“Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.” PGP implements the IETF standard RFC4880. PGP is used by More4apps to create detached digital signatures to sign files without modifying the original file.”
