In August 2019 [5] the default key server was switched to hagrid, [6] a new verifying key server located at keys.openpgp.org. This improved the quality of search results for public keys and increased control for users over their public keys stored on the server.
A separate key server, known as the PGP Certificate Server, was developed by PGP, Inc. and was used as the software (through version 2.5.x for the server) for the default key server in PGP through version 8.x (for the client software), keyserver.pgp.com. Network Associates was granted a patent co-authored by Jon Callas (United States Patent 6336186) [3] on the key server concept.
In cryptography, the OpenPGP card [1] is an ISO/IEC 7816-4, -8 compatible smart card [2] that is integrated with many OpenPGP functions. Using this smart card, various cryptographic tasks (encryption, decryption, digital signing/verification, authentication etc.) can be performed. It allows secure storage of secret key material; all versions of ...
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.
In public-key cryptography, a key signing party is an event at which people present their public keys to others in person, who, if they are confident the key actually belongs to the person who claims it, digitally sign the certificate containing that public key and the person's name, etc. [1] Key signing parties are common within the PGP and ...
The primary threat to the security of a fingerprint is a second-preimage attack, where an attacker constructs a key pair whose public key hashes to a fingerprint that matches the victim's fingerprint. The attacker could then present his public key in place of the victim's public key to masquerade as the victim.
OpenKeychain is listed on the official OpenPGP homepage [5] and the well-known developer collective Guardian Project recommends it instead of APG to encrypt emails. [6] TechRepublic published an article about it and conclude that "OpenKeychain happens to be one of the easiest encryption tools available for Android (that also happens to best ...
Autocrypt is a cryptographic protocol for email clients aiming to simplify key exchange and enabling encryption. [citation needed] Version 1.0 of the Autocrypt specification was released in December 2017.
