This is your secret key that is used to decrypt messages encrypted with your public key and sign messages, proving you are the owner of the key pair.Įven using the default encryption settings in Kleopatra, PGP encryption is considered to be very secure, with no known instances of private keys having been reverse-engineered from public keys. Others can also use your public key to verify messages sent by you signed with the corresponding private key. This is your public-facing key that others can use to encrypt messages to be read only by you. To use PGP for sending, receiving, and signing encrypted messages, you will first need to use Kleopatra to generate a PGP key pair as a certificate stored in the application. The GnuPG software suite, of which Kleopatra is a core application, is free software that was created to help give computer users privacy and advanced control over their computer operations. One of the most commonly used and widely available PC applications for PGP is Kleopatra, a free and open-source program for Windows and Linux. PGP is used not only to encrypt messages for selective viewing by an intended recipient but also to sign messages as a way of proving content was written by a specific individual or entity. The ways in which keys are generated are different but the concept remains the same: the private key is used to verify ownership of the public key. A modern analogy for PGP would be cryptocurrency keys, where a private key is needed to spend coins sent to an address which is ultimately derived from a corresponding public key. What is PGP?Īn encryption program first developed in 1991, PGP is short for “Pretty Good Privacy.” It uses series of cryptographic algorithms and techniques to create a key pair, consisting of a private and public key. This includes creating a key pair, importing certificates & public keys, signing & encrypting messages, decrypting messages, and verifying signed messages. In this guide we explain the basics of what PGP is and everything you need to know to use Kleopatra, one of the most widely used applications for GnuPG.
