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. Phil Zimmermann developed PGP in 1991.[4]

PGP and similar software follow the OpenPGP standard (RFC 4880), an open standard for encrypting and decrypting data. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems.[5]

Despite "Pretty Good" in the PGP name, it (and OpenPGP and all implementations of) has lots of problems and "Cryptography engineers have been tearing their hair out over PGP’s deficiencies for (literally) decades."[6][7] and e.g. Python 3.14 will stop using PGP (and use Sigstore instead, with "short-lived keys"), since it "requires the maintenance and protection of long-lived private keys".[8]
