GnuPG is a hybrid-encryption software program because it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient's public key to encrypt a session key which is used only once. This mode of operation is part of the OpenPGP standard and ...
The smart card daemon, in combination with the supported smart card readers, [6] as implemented in GnuPG, can be used for many cryptographic applications. With gpg-agent in GnuPG 2, an ssh-agent implementation using GnuPG, an OpenPGP card can be used for SSH authentication also.
Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems. [ 5 ] The OpenPGP standard has received criticism for its long-lived keys and steep learning curve, [ 6 ] as well as the Efail security vulnerability that previously arose when select e-mail programs used OpenPGP with S/MIME.
The original creation of Gpg4win was initiated and funded by Germany's Federal Office for Information Security (BSI) in 2005, [2] [3] resulting in the release of Gpg4win 1.0.0 on 6 April 2006; [4] however Gpg4win and all included tools are free and open source software, and it is typically the non-proprietary option for privacy recommended [5] [6] to Windows users.
All OpenPGP-compliant implementations include a certificate vetting scheme to assist with this; its operation has been termed a web of trust. OpenPGP certificates (which include one or more public keys along with owner information) can be digitally signed by other users who, by that act, endorse the association of that public key with the person or entity listed in the certificate.
Stream ciphers are defined as using plain text digits that are combined with a pseudorandom cipher digit stream. Stream ciphers are typically faster than block ciphers and may have lower hardware complexity, but may be more susceptible to attacks.
WinPT represents a collection of user interface tools designed to ease the use of asymmetric encryption software. Based on GnuPG , and OpenPGP -compatible, WinPT is intended for Windows users to use for everyday message signing, verification, encryption and general key management.
