OpenPGP provides cryptographic privacy and authentication, utilizing asymmetric cryptography for secure communication and identity validation.
OpenPGP is an open encryption standard and software implementation that provides cryptographic privacy and authentication for data communication. It uses a combination of symmetric-key and public-key cryptography to provide confidentiality and integrity of data.
OpenPGP is based on the PGP (Pretty Good Privacy) encryption software originally developed by Phil Zimmermann in 1991. It uses asymmetric cryptography to allow people to encrypt and decrypt messages and securely exchange keys with each other. This allows two parties, who have never met in person, to communicate privately and authenticate each other's identities.
Some key features of OpenPGP include:
There are several popular OpenPGP implementations, including GNU Privacy Guard (GnuPG) and other OpenPGP-compliant tools. OpenPGP is most commonly used for signing, encrypting, and decrypting texts, emails, files, directories and partitions.
